NAME
ctwm - Claude's Tab Window Manager for the X Window System
SYNTAX
ctwm [-display dpy] [-s] [-cfgchk] [-f initfile] [-v] [-n] [-k] [-K m4file] [-w [win-id]]
DESCRIPTION
ctwm is a window manager for the X Window System. It provides titlebars, shaped windows, virtual screens
(workspaces), several forms of icon management, user-defined macro functions, click-to-type and
pointer-driven keyboard focus, and user-specified key and pointer button bindings. It is actually twm(1)
(Tab Window Manager) from the MIT X11 distribution slightly modified to accommodate the use of several
virtual screens (workspaces). It is heavily inspired from the Hewlett-Packard vuewm window manager. In
addition, ctwm can use coloured, shaped icons and background root pixmaps in XPM format [from Arnaud Le
Hors], any format understood by the imconv package [from the San Diego Supercomputer Center], and xwd
files. ctwm can be compiled to use both, either or none of the above icon/pixmap formats.
This program is usually started by the user's session manager or startup script. When used from xdm(1)
or xinit(1) without a session manager, ctwm is frequently executed in the foreground as the last client.
When run this way, exiting ctwm causes the session to be terminated (i.e. logged out).
By default, application windows are surrounded by a ‘frame’ with a titlebar at the top and a special
border around the window. The titlebar contains the window's name, a rectangle that is lit when the
window is receiving keyboard input, and function boxes known as ‘titlebuttons’ at the left and right
edges of the titlebar.
Pressing pointer Button1 (usually the left-most button unless it has been changed with xmodmap) on a
titlebutton will invoke the function associated with the button. In the default interface, windows are
iconified by clicking (pressing and then immediately releasing) the left titlebutton (which looks like a
Dot). Conversely, windows are deiconified by clicking in the associated icon or entry in the icon
manager (see description of the variable ShowIconManager and of the function f.showiconmgr).
Windows are resized by pressing the right titlebutton (which resembles a group of nested squares),
dragging the pointer over edge that is to be moved, and releasing the pointer when the outline of the
window is the desired size. Similarly, windows are moved by pressing in the title or highlight region,
dragging a window outline to the new location, and then releasing when the outline is in the desired
position. Just clicking in the title or highlight region raises the window without moving it.
When new windows are created, ctwm will honor any size and location information requested by the user
(usually through -geometry command line argument or resources for the individual applications).
Otherwise, an outline of the window's default size, its titlebar, and lines dividing the window into a
3x3 grid that track the pointer are displayed. Clicking pointer Button1 will position the window at the
current position and give it the default size. Pressing pointer Button2 (usually the middle pointer
button) and dragging the outline will give the window its current position but allow the sides to be
resized as described above. Clicking pointer Button3 (usually the right pointer button) will give the
window its current position but attempt to make it long enough to touch the bottom the screen.
OPTIONS
ctwm accepts the following command line options:
-display dpy
This option specifies the X server to use.
-s This option indicates that only the default screen (as specified by -display or by the DISPLAY
environment variable) should be managed. By default, ctwm will attempt to manage all screens on
the display.
-cfgchk This option causes ctwm to only try to parse the config file, and indicate whether errors are
found.
-f filename
This option specifies the name of the startup file to use. ctwm will first try to load
filename.num, where num is the screen number. If it fails, it will try to load filename. By
default, ctwm will look in the user's home directory for files named .ctwmrc.num, .ctwmrc,
.twmrc.num, or .twmrc (where num is a screen number).
-v This option indicates that ctwm should print error messages whenever an unexpected X Error event
is received. This can be useful when debugging applications but can be distracting in regular
use.
-n This option indicates that ctwm should not filter the startup file through m4. Available only if
ctwm is compiled with the USEM4 flag.
-k This option indicates that ctwm should keep the definitions it prepends to your startup file when
filtering through m4 in /tmp. Available only if ctwm is compiled with the USEM4 flag.
-K m4file
This option indicates that ctwm should keep the result of filtering your startup file through m4
in the named file. Available only if ctwm is compiled with the USEM4 flag.
-version
ctwm just prints its version number.
-info ctwm prints its detailed version and compile time options.
-w [win-id]
If -w is specified without a win-id value, ctwm does not take over the whole screen(s), instead
it creates a new window that becomes its root window. if the win-id value is given, it is
considered to be the id of an existing window, in which case, ctwm will try to use this window as
root window. You can run any number of instantiation of ctwm at the same time. You can even have
embedded ctwm instantiations. This is totally useless, but I like it. The f.adoptwindow function
can be used to capture an existing window belonging to another ctwm. A possible use of such mode
can be to test new configuration file without restarting ctwm.
-W This option tells ctwm not to display any welcome when starting.
CUSTOMIZATION
Much of ctwm's appearance and behavior can be controlled by providing a startup file in one of the
following locations (searched in order for each screen being managed when ctwm begins):
$HOME/.ctwmrc.screennumber
The screennumber is a small positive number (e.g. 0, 1, etc.) representing the screen number
(e.g. the last number in the DISPLAY environment variable host:displaynum.screennum) that would
be used to contact that screen of the display. This is intended for displays with multiple
screens of differing visual types.
$HOME/.ctwmrc
This is the usual name for an individual user's startup file.
$HOME/.twmrc.screennumber
$HOME/.twmrc
The users twm startup file.
/usr/lib/X11/twm/system.ctwmrc
If none of the preceding files are found, ctwm will look in this file for a default
configuration. This is often tailored by the site administrator to provide convenient menus or
familiar bindings for novice users.
If no startup files are found, ctwm will use the built-in defaults described above. The only resource
used by ctwm is bitmapFilePath for a colon-separated list of directories to search when looking for
bitmap files (for more information, see the Athena Widgets manual and xrdb(1)).
ctwm startup files are logically broken up into three types of specifications: Variables, Bindings,
Menus. The Variables section must come first and is used to describe the fonts, colors, cursors, border
widths, icon and window placement, highlighting, autoraising, layout of titles, warping, use of the icon
manager. The Bindings section usually comes second and is used to specify the functions that should be
to be invoked when keyboard and pointer buttons are pressed in windows, icons, titles, and frames. The
Menus section gives any user-defined menus (containing functions to be invoked or commands to be
executed).
Variable names and keywords are case-insensitive. Strings must be surrounded by double quote characters
(e.g. ‘blue’) and are case-sensitive. A pound sign (#) outside of a string causes the remainder of the
line in which the character appears to be treated as a comment.
M4 PREPROCESSING
ctwm uses m4(1) to pre-process its setup files. When ctwm starts up, it opens a file for input as
described above. But, it processes that file through m4 before parsing it. So, you can use m4 macros to
perform operations at runtime. This makes it very easy to work when you use many different displays,
with different characteristics. For example, If you want to set the lower right section of the screen to
be your IconRegion, (see below for details on the IconRegion variable) you can use m4 directives and
pre-defined symbols to calculate the region you want. For example:
define(IRegion, translit(eval(WIDTH/3)*eval(HEIGHT/2)+eval(WIDTH-WIDTH/3)-0, *, x))
IconRegion "IRegion" SOUTH EAST 75 25
will define the lower half, and right-hand third of the screen. The above makes use of symbols that are
predefined in m4 by ctwm. The symbols WIDTH and HEIGHT are calculated by ctwm and written into a
temporary file for m4 to use. The following symbols are predefined by ctwm:
SERVERHOST This variable is set to the name of the machine that is running the X server.
CLIENTHOST The machine that is running the clients. (ie, ctwm)
HOSTNAME The canonical hostname running the clients. (ie. a fully-qualified version of
CLIENTHOST)
USER The name of the user running the program. Gotten from the environment.
HOME The user's home directory. Gotten from the environment.
PIXMAP_DIRECTORY
The directory where the ctwm pictures are installed.
VERSION The X major protocol version. As seen by ProtocolVersion(3).
REVISION The X minor protocol revision. As seen by ProtocolRevision(3).
VENDOR The vendor of your X server. For example: MIT X Consortium.
RELEASE The release number of your X server. For MIT X11R5, this is 5.
WIDTH The width of your display in pixels.
HEIGHT The height of your display in pixels.
X_RESOLUTION The X resolution of your display in pixels per meter.
Y_RESOLUTION The Y resolution of your display in pixels per meter.
PLANES The number of bit planes your display supports in the default root window.
BITS_PER_RGB The number of significant bits in an RGB color. (log base 2 of the number of distinct
colors that can be created. This is often different from the number of colors that can
be displayed at once.)
TWM_TYPE Tells which twm offshoot is running. It will always be set to the string ‘ctwm’ in this
program. This is useful for protecting parts of your .twmrc file that ctwm proper won't
understand (like WorkSpaces) so that it is still usable with other twm programs.
TWM_VERSION Tells which ctwm version is running in the form of a floating point number.
CLASS Your visual class. Will return one of StaticGray, GrayScale, StaticColor, PseudoColor,
TrueColor, DirectColor, or, if it cannot determine what you have, NonStandard.
COLOR This will be either ‘Yes’ or ‘No’. This is just a wrapper around the above definition.
Returns ‘Yes’ on *Color, and ‘No’ on StaticGray and GrayScale.
XPM Is defined only if ctwm was compiled with XPM.
JPEG Is defined only if ctwm was compiled with JPEG.
IMCONV Is defined only if ctwm was compiled with IMCONV.
GNOME Is defined only if ctwm was compiled with GNOME.
SOUNDS Is defined only if ctwm was compiled with USE_SOUND.
SESSION Is defined only if ctwm was compiled with USE_SESSION.
I18N Is defined only if ctwm was compiled with I18N.
TWM_CAPTIVE This will be either ‘Yes’ or ‘No’. ‘Yes’ if the current ctwm is captive (flag -w), ‘No’
in the other case.
TWM_CAPTIVE_NAME
Defined only if TWM_CAPTIVE is also defined. Contains the name of the captive ctwm (-name
flag);
You may well find that if you research the m4(1) manual well, and understand the power of m4, this will
be a very useful and powerful tool. But, if you use any of the symbols which are predefined by m4, you
are in severe danger! For example, the Sun m4 predefines shift, so if you use that name in your .ctwmrc,
you are out of luck.
The availability of the m4 preprocessing is subject to the compilation define USEM4.
VARIABLES
Many of the aspects of ctwm's user interface are controlled by variables that may be set in the user's
startup file. Some of the options are enabled or disabled simply by the presence of a particular
keyword. Other options require keywords, numbers, strings, or lists of all of these.
Lists are surrounded by braces and are usually separated by whitespace or a newline. For example:
AutoRaise { "emacs" "XTerm" "Xmh" }
or
AutoRaise
{
"emacs"
"XTerm"
"Xmh"
}
When a variable containing a list of strings representing windows is searched (e.g. to determine whether
or not to enable autoraise as shown above), a string must be an exact, case-sensitive match to the
window's name (given by the WM_NAME window property), resource name or class name (both given by the
WM_CLASS window property). The preceding example would enable autoraise on windows named ‘emacs’ as well
as any xterm (since they are of class ‘XTerm’) or xmh windows (which are of class ‘Xmh’).
String arguments that are interpreted as filenames (see the Pixmaps, Cursors, and IconDirectory below)
will prepend the user's directory (specified by the HOME environment variable) if the first character is
a tilde (~). If, instead, the first character is a colon (:), the name is assumed to refer to one of the
internal bitmaps that are used to create the default titlebars symbols: :xlogo or :iconify (both refer
to the X used for the iconify button), :resize (the nested squares used by the resize button), and
:question (the question mark used for non-existent bitmap files).
The following variables may be specified at the top of a ctwm startup file. Lists of window name prefix
strings are indicated by win-list. Optional arguments are shown in square brackets:
AlwaysOnTop { win-list }
This variable specifies a list of windows (all windows if the list is defaulted) that ctwm will
try its best to maintain on top of others. This doesn't work in all case.
AlwaysShowWindowWhenMovingFromWorkspaceManager
When ReallyMoveInWorkspaceManager is present and the user is moving a window from the
WorkSpaceMap, ctwm display the actual window only if it crosses the current active workspace. If
AlwaysShowWindowWhenMovingFromWorkspaceManager is present, the actual window is always visible
during the move, regardless of whether it crosses the current workspace or not. The Shift key
toggles this behaviour.
AlwaysSqueezeToGravity [{ win-list }]
This variable indicates that ctwm should obey window gravity when squeezing a window even when
the window has a titlebar. Normally, ctwm will always squeeze a window that has a titlebar
toward the north. The optional win-list may be used to control which windows this applies on.
AnimationSpeed speed
The speed argument is a non-negative integer. It determines the number of times a second
animations (if any) are updated. If speed is 0, animations are freezed. The default value is 0.
AutoFocusToTransients
Transient windows get focus automatically when created. Useful with programs that have keyboard
shortcuts that pop up windows.
AutoLower { win-list }
This variable specifies a list of windows (all windows if the list is defaulted) to be
automatically lowered whenever the point leaves a window. This action can be interactively
enabled or disabled on individual windows using the function f.autolower.
AutoOccupy
This variable specifies that clients will automatically change their occupation when their name
or icon name changes. The new occupation will be recalculated from the Occupy and OccupyAll
fields in the .ctwmrc file.
AutoRaise { win-list }
This variable specifies a list of windows (all windows if the list is defaulted) to be
automatically raised whenever the pointer has come to rest in a window for the amount of time
specified by the RaiseDelay variable. This action can be interactively enabled or disabled on
individual windows using the function f.autoraise.
AutoRaiseIcons
Icons are raised when the cursor enters it. Useful with ShrinkIconTitles.
AutoRelativeResize
This variable indicates that dragging out a window size (either when initially sizing the window
with pointer Button2 or when resizing it) should not wait until the pointer has crossed the
window edges. Instead, moving the pointer automatically causes the nearest edge or edges to move
by the same amount. This allows the resizing of windows that extend off the edge of the screen.
If the pointer is in the center of the window, or if the resize is begun by pressing a
titlebutton, ctwm will still wait for the pointer to cross a window edge (to prevent accidents).
This option is particularly useful for people who like the press-drag-release method of sweeping
out window sizes.
AutoSqueeze { win-list }
These windows will be auto-squeezed (see f.squeeze). i.e. automatically unsqueezed when they get
focus, and squeezed when they loose it. Useful for the workspace manager. Not authorized for icon
managers.
BeNiceToColormap
By defaults new colors are allocated for shadows when a 3D look is used, but when you specify
BeNiceToColormap ctwm uses stipling instead of new colors, the effect is less beautiful, but
acceptable. In this case ClearShadowContrast and DarkShadowContrast have no effects.
BorderBottom pixels
This variable specifies the width in pixels of a forbidden zone at the bottom of the screen. All
constrained window functions (f.movepack, f.move with DontMoveOff, etc...) will consider this
zone as offscreen. Default is 0.
BorderColor string [{ wincolorlist }]
This variable specifies the default color of the border to be placed around all non-iconified
windows, and may only be given within a Color or Monochrome list. The optional wincolorlist
specifies a list of window and color name pairs for specifying particular border colors for
different types of windows. For example:
BorderColor "gray50"
{
"XTerm" "red"
"xmh" "green"
}
The default is ‘black’.
BorderLeft pixels
This variable specifies the width in pixels of a forbidden zone at the left of the screen. All
constrained window functions (f.movepack, f.move with DontMoveOff, etc...) will consider this
zone as offscreen. Default is 0.
BorderResizeCursors
This variable specifies that ctwm should use resizing cursors when the pointer is on the window
border. To be used preferably when you have bound a button to f.resize in the frame context.
BorderRight pixels
This variable specifies the width in pixels of a forbidden zone at the right of the screen. All
constrained window functions (f.movepack, f.move with DontMoveOff, etc...) will consider this
zone as offscreen. Default is 0.
BorderShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses for 3D window borders, when
UseThreeDBorders is selected.
BorderTileBackground string [{ wincolorlist }]
This variable specifies the default background color in the gray pattern used in unhighlighted
borders (only if NoHighlight hasn't been set), and may only be given within a Color or Monochrome
list. The optional wincolorlist allows per-window colors to be specified. The default is
‘white’.
BorderTileForeground string [{ wincolorlist }]
This variable specifies the default foreground color in the gray pattern used in unhighlighted
borders (only if NoHighlight hasn't been set), and may only be given within a Color or Monochrome
list. The optional wincolorlist allows per-window colors to be specified. The default is
‘black’.
BorderTop pixels
This variable specifies the width in pixels of a forbidden zone at the top of the screen. All
constrained window functions (f.movepack, f.move with DontMoveOff, etc...) will consider this
zone as offscreen. Default is 0.
BorderWidth pixels
This variable specifies the width in pixels of the border surrounding all client window frames if
ClientBorderWidth has not been specified. This value is also used to set the border size of
windows created by ctwm (such as the icon manager). The default is 2.
ButtonIndent pixels
This variable specifies the amount by which titlebuttons should be indented on all sides.
Positive values cause the buttons to be smaller than the window text and highlight area so that
they stand out. Setting this and the TitleButtonBorderWidth variables to 0 makes titlebuttons be
as tall and wide as possible. The default is 1 if UseThreeDTitles is not set, 0 if it is set.
CenterFeedbackWindow
The moving and resizing information window is centered in the middle of the screen instead of the
top left corner.
ClearShadowContrast contrast
Indicates to ctwm how to calculate the clear shadow color for 3D items. The value is a comprised
between 0 and 100. The formula used is :
clear.{RGB} = (65535 - color.{RGB}) * (contrast / 100).
Has no effect if BeNiceToColormap is active.
ClientBorderWidth
This variable indicates that border width of a window's frame should be set to the initial border
width of the window, rather than to the value of BorderWidth.
Color { colors-list }
This variable specifies a list of color assignments to be made if the default display is capable
of displaying more than simple black and white. The colors-list is made up of the following
color variables and their values: DefaultBackground, DefaultForeground, MenuBackground,
MenuForeground, MenuTitleBackground, MenuTitleForeground, and MenuShadowColor. The following
color variables may also be given a list of window and color name pairs to allow per-window
colors to be specified (see BorderColor for details): BorderColor, IconManagerHighlight,
BorderTileBackground, BorderTileForeground, TitleBackground, TitleForeground, IconBackground,
IconForeground, IconBorderColor, IconManagerBackground, and IconManagerForeground. For example:
Color
{
MenuBackground "gray50"
MenuForeground "blue"
BorderColor "red" { "XTerm" "yellow" }
TitleForeground "yellow"
TitleBackground "blue"
}
All of these color variables may also be specified for the Monochrome variable, allowing the same
initialization file to be used on both color and monochrome displays.
ConstrainedMoveTime milliseconds
This variable specifies the length of time between button clicks needed to begin a constrained
move operation. Double clicking within this amount of time when invoking f.move will cause the
window only be moved in a horizontal or vertical direction. Setting this value to 0 will disable
constrained moves. The default is 400 milliseconds.
Cursors { cursor-list }
This variable specifies the glyphs that ctwm should use for various pointer cursors. Each cursor
may be defined either from the cursor font or from two bitmap files. Shapes from the cursor font
may be specified directly as:
cursorname "string"
where cursorname is one of the cursor names listed below, and string is the name of a glyph as
found in the file /usr/include/X11/cursorfont.h (without the ‘XC_’ prefix). If the cursor is to
be defined from bitmap files, the following syntax is used instead:
cursorname "image" "mask"
The image and mask strings specify the names of files containing the glyph image and mask in
bitmap(1) form. The bitmap files are located in the same manner as icon bitmap files. The
following example shows the default cursor definitions:
Cursors
{
Frame "top_left_arrow"
Title "top_left_arrow"
Icon "top_left_arrow"
IconMgr "top_left_arrow"
Move "fleur"
Resize "fleur"
Menu "sb_left_arrow"
Button "hand2"
Wait "watch"
Select "dot"
Destroy "pirate"
}
DarkShadowContrast contrast
Indicates to ctwm how to calculate the dark shadow color for 3D items. The value is a comprised
between 0 and 100. The formula used is :
dark.{RGB} = color.{RGB} * ((100 - contrast) / 100),
Has no effect if BeNiceToColormap is active.
DecorateTransients
This variable indicates that transient windows (those containing a WM_TRANSIENT_FOR property)
should have titlebars. By default, transients are not reparented.
DefaultBackground string
This variable specifies the background color to be used for sizing and information windows. The
default is ‘white’.
DefaultForeground string
This variable specifies the foreground color to be used for sizing and information windows. The
default is ‘black’.
DontIconifyByUnmapping { win-list }
This variable specifies a list of windows that should not be iconified by simply unmapping the
window (as would be the case if IconifyByUnmapping had been set). This is frequently used to
force some windows to be treated as icons while other windows are handled by the icon manager.
DontMoveOff
This variable indicates that windows should not be allowed to be moved off the screen. It can be
overridden by the f.forcemove function.
DontPaintRootWindow
This variable tells ctwm not to paint the root window, whatever you told in the Workspaces
specification. This is useful to have pixmaps in the Workspace Map but not on the root window.
DontSave { win-list }
These windows won't have their characteristics saved for the session manager.
DontSetInactive { win-list }
These windows won't be set to InactiveState when they become invisible due to a change workspace.
This has been added because some ill-behaved clients (Frame5) don't like this.
DontSqueezeTitle [{ win-list }]
This variable indicates that titlebars should not be squeezed to their minimum size as described
under SqueezeTitle below. If the optional window list is supplied, only those windows will be
prevented from being squeezed.
DontToggleWorkSpaceManagerState
Turns off the feature toggling the workspace manager state to/from map/button state when you
press ctrl and the workspace manager window is in focus.
DontWarpCursorInWMap
Tells ctwm not to warp the cursor to the corresponding actual window when you click in a small
window in the workspace map.
ForceIcons
This variable indicates that icon pixmaps specified in the Icons variable should override any
client-supplied pixmaps.
FramePadding pixels
This variable specifies the distance between the titlebar decorations (the button and text) and
the window frame. The default is 2 pixels if UseThreeDTitles is not set, 0 if it is set.
IconBackground string [{ win-list }]
This variable specifies the background color of icons, and may only be specified inside of a
Color or Monochrome list. The optional win-list is a list of window names and colors so that
per-window colors may be specified. See the BorderColor variable for a complete description of
the win-list. The default is ‘white’.
IconBorderColor string [{ win-list }]
This variable specifies the color of the border used for icon windows, and may only be specified
inside of a Color or Monochrome list. The optional win-list is a list of window names and colors
so that per-window colors may be specified. See the BorderColor variable for a complete
description of the win-list. The default is ‘black’.
IconBorderWidth pixels
This variable specifies the width in pixels of the border surrounding icon windows. The default
is 2.
IconDirectory string
This variable specifies the directory that should be searched if a bitmap file cannot be found in
any of the directories in the bitmapFilePath resource.
IconFont string
This variable specifies the font to be used to display icon names within icons. The default is
‘variable’.
IconForeground string [{ win-list }]
This variable specifies the foreground color to be used when displaying icons, and may only be
specified inside of a Color or Monochrome list. The optional win-list is a list of window names
and colors so that per-window colors may be specified. See the BorderColor variable for a
complete description of the win-list. The default is ‘black’.
IconifyByUnmapping [{ win-list }]
This variable indicates that windows should be iconified by being unmapped without trying to map
any icons. This assumes that the user is will remap the window through the icon manager, the
f.warpto function, or the TwmWindows menu. If the optional win-list is provided, only those
windows will be iconified by simply unmapping. Windows that have both this and the
IconManagerDontShow options set may not be accessible if no binding to the TwmWindows menu is set
in the user's startup file.
IconifyStyle string
Where string is either "normal", "mosaic", "zoomin", "zoomout" or "sweep". Tells ctwm to use some
fancy graphical effects when iconifying windows.
IconJustification string
Where string is either "left", "center" or "right". Tells ctwm how to justify the icon image
against the icon title (if any).
IconManagerBackground string [{ win-list }]
This variable specifies the background color to use for icon manager entries, and may only be
specified inside of a Color or Monochrome list. The optional win-list is a list of window names
and colors so that per-window colors may be specified. See the BorderColor variable for a
complete description of the win-list. The default is ‘white’.
IconManagerDontShow [{ win-list }]
This variable indicates that the icon manager should not display any windows. If the optional
win-list is given, only those windows will not be displayed. This variable is used to prevent
windows that are rarely iconified (such as xclock or xload) from taking up space in the icon
manager.
IconManagerFont string
This variable specifies the font to be used when displaying icon manager entries. The default is
‘variable’.
IconManagerForeground string [{ win-list }]
This variable specifies the foreground color to be used when displaying icon manager entries, and
may only be specified inside of a Color or Monochrome list. The optional win-list is a list of
window names and colors so that per-window colors may be specified. See the BorderColor variable
for a complete description of the win-list. The default is ‘black’.
IconManagerGeometry string [ columns ]
This variable specifies the geometry of the icon manager window. The string argument is standard
geometry specification that indicates the initial full size of the icon manager. The icon
manager window is then broken into columns pieces and scaled according to the number of entries
in the icon manager. Extra entries are wrapped to form additional rows. The default number of
columns is 1.
IconManagerHighlight string [{ win-list }]
This variable specifies the border color to be used when highlighting the icon manager entry that
currently has the focus, and can only be specified inside of a Color or Monochrome list. The
optional win-list is a list of window names and colors so that per-window colors may be
specified. See the BorderColor variable for a complete description of the win-list. The default
is ‘black’.
IconManagers { iconmgr-list }
This variable specifies a list of icon managers to create. Each item in the iconmgr-list has the
following format:
"winname" ["iconname"] "geometry" columns
where winname is the name of the windows that should be put into this icon manager, iconname is
the name of that icon manager window's icon, geometry is a standard geometry specification, and
columns is the number of columns in this icon manager as described in IconManagerGeometry. For
example:
IconManagers
{
"XTerm" "=300x5+800+5" 5
"myhost" "=400x5+100+5" 2
}
Clients whose name or class is ‘XTerm’ will have an entry created in the ‘XTerm’ icon manager.
Clients whose name was ‘myhost’ would be put into the ‘myhost’ icon manager.
IconManagerShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses for 3D IconManager entries, when
UseThreeDIconManagers is selected.
IconManagerShow { win-list }
This variable specifies a list of windows that should appear in the icon manager. When used in
conjunction with the IconManagerDontShow variable, only the windows in this list will be shown in
the icon manager.
IconMenuDontShow { win-list }
Don't show the name of these windows in the TwmIcons menu.
IconRegion geomstring vgrav hgrav gridwidth gridheight [iconjust]
[iconregjust] [iconregalign] [{ win-list }]
This variable specifies an area on the root window in which icons are placed if no specific icon
location is provided by the client. The geomstring is a quoted string containing a standard
geometry specification. If more than one IconRegion lines are given, icons will be put into the
succeeding icon regions when the first is full. The vgrav argument should be either North or
South and is used to control whether icons are first filled in from the top or bottom of the
icon region. Similarly, the hgrav argument should be either East or West and is used to control
whether icons should be filled in from left or from the right. Icons are laid out within the
region in a grid with cells gridwidth pixels wide and gridheight pixels high. The optional
win-list argument tells ctwm that if such a window is iconified, and there is enough room in this
icon region for its icon, then place it here. The optional iconjust, iconregjust and iconregalign
can be used to give specific values of IconJustification, IconRegionJustification and
IconRegionAlignement for this IconRegion.
IconRegionAlignement string
Where string is either "top", "center" "bottom" or "border". Tells ctwm how to align icons
inside their place in the IconRegion. If ‘border’ is given, the justification will be ‘top’ if
the icon region gravity is ‘north’ and ‘bottom’ if the icon region gravity is ‘south’.
IconRegionJustification string
Where string is either "left", "center" "right" or "border". Tells ctwm how to justify icons
inside their place in the IconRegion. If ‘border’ is given, the justification will be ‘left’ if
the icon region gravity is ‘west’ and ‘right’ if the icon region gravity is ‘east’.
Icons { win-list }
This variable specifies a list of window names and the bitmap filenames that should be used as
their icons. For example:
Icons
{
"XTerm" "xterm.icon"
"xfd" "xfd_icon"
}
Windows that match ‘XTerm’ and would not be iconified by unmapping, would try to use the icon
bitmap in the file ‘xterm.icon’.If ForceIcons is specified, this bitmap will be used even if the
client has requested its own icon pixmap.
IgnoreCaseInMenuSelection
Used when moving the pointer inside a menu with the keyboard. When you type a letter, the pointer
goes to the next entry beginning with this letter. If IgnoreCaseInMenuSelection is present, this
selection ignores the case of this first letter.
IgnoreLockModifier
If present, all bindings (buttons and keys) will ignore the LockMask. Useful if you often use
caps lock, and don't want to define twice all your bindings.
IgnoreModifier
All bindings (buttons and keys) will ignore the modifiers you specified. It is useful when you
use caps locks or num locks. You don't need IgnoreLockModifier any more with this option.
IgnoreModifier { lock m2 }
IgnoreTransient
List of windows for which to ignore transients.
IgnoreTransient { "Wine" }
InterpolateMenuColors
This variable indicates that menu entry colors should be interpolated between entry specified
colors. In the example below:
Menu "mymenu"
{
"Title" ("black":"red") f.title
"entry1" f.nop
"entry2" f.nop
"entry3" ("white":"green") f.nop
"entry4" f.nop
"entry5" ("red":"white") f.nop
}
the foreground colors for ‘entry1’ and ‘entry2’ will be interpolated between black and white, and
the background colors between red and green. Similarly, the foreground for ‘entry4’ will be
half-way between white and red, and the background will be half-way between green and white.
MakeTitle { win-list }
This variable specifies a list of windows on which a titlebar should be placed and is used to
request titles on specific windows when NoTitle has been set.
MapWindowBackground color [{ win-list }]
This variable specifies the background colors to use for small windows in the workspace map
window and may only be specified inside of a Color or Monochrome list. The optional win-list is a
list of window names and colors so that per-window colors may be specified. If there is neither
MapWindowBackground, nor MapWindowForeground the window title colors are used.
MapWindowCurrentWorkSpace { border_color [background] [foreground] [bitmap] }
Specify the appearence of the map window corresponding to the current workspace.
MapWindowDefaultWorkSpace { border_color [background] [foreground] [bitmap] }
Specify the appearence of the map window corresponding to the workspaces other than the current
workspace when no root background information has been provided to ctwm in the WorkSpace command.
Not used in others cases.
MapWindowForeground color [{ win-list }]
This variable specifies the foreground colors to use for small windows in the workspace map
window and may only be specified inside of a Color or Monochrome list. The optional win-list is a
list of window names and colors so that per-window colors may be specified. If there is neither
MapWindowBackground, nor MapWindowForeground the window title colors are used.
MaxIconTitleWidth width
The integer argument tells ctwm the maximun width to use for an icon title. If an icon title is
larger than width, it is truncated.
MaxWindowSize string
This variable specifies a geometry in which the width and height give the maximum size for a
given window. This is typically used to restrict windows to the size of the screen. The default
is ‘30000x30000’.
MenuBackground string
This variable specifies the background color used for menus, and can only be specified inside of
a Color or Monochrome list. The default is ‘white’.
MenuFont string
This variable specifies the font to use when displaying menus. The default is ‘variable’.
MenuForeground string
This variable specifies the foreground color used for menus, and can only be specified inside of
a Color or Monochrome list. The default is ‘black’.
MenuShadowColor string
This variable specifies the color of the shadow behind pull-down menus and can only be specified
inside of a Color or Monochrome list. The default is ‘black’.
MenuShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses for 3D menus, when UseThreeDMenus is
selected.
MenuTitleBackground string
This variable specifies the background color for f.title entries in menus, and can only be
specified inside of a Color or Monochrome list. The default is ‘white’.
MenuTitleForeground string
This variable specifies the foreground color for f.title entries in menus and can only be
specified inside of a Color or Monochrome list. The default is ‘black’.
Monochrome { colors }
This variable specifies a list of color assignments that should be made if the screen has a depth
of 1. See the description of Color.
MoveDelta pixels
This variable specifies the number of pixels the pointer must move before the f.move function
starts working. Also see the f.deltastop function. The default is zero pixels.
MovePackResistance pixels
This variable specifies the number of pixels of the movepack and movepush resistance. See
f.movepack and f.movepush.
MoveOffResistance pixels
This variable specifies the number of pixels of the moveoff resistance. If pixels is positive,
DontMoveOff will only prevent you from going off the edge if you're within n pixels off the edge.
If you go further, DontMoveOff gives up and lets you go as far as you wish. f.forcemove still
allows you to totally ignore DontMoveOff. A negative value puts you back into ‘never moveoff’
mode (it's the default).
NoBackingStore
This variable indicates that ctwm's menus should not request backing store to minimize repainting
of menus. This is typically used with servers that can repaint faster than they can handle
backing store.
NoBorder { win-list }
These windows won't have borders. If you want no borders on all windows, use the BorderWidth
keyword.
NoCaseSensitive
This variable indicates that case should be ignored when sorting icon names in an icon manager.
This option is typically used with applications that capitalize the first letter of their icon
name.
NoDefaults
This variable indicates that ctwm should not supply the default titlebuttons and bindings. This
option should only be used if the startup file contains a completely new set of bindings and
definitions.
NoGrabServer
This variable indicates that ctwm should not grab the server when popping up menus and moving
opaque windows.
NoHighlight [{ win-list }]
This variable indicates that borders should not be highlighted to track the location of the
pointer. If the optional win-list is given, highlighting will only be disabled for those
windows. When the border is highlighted, it will be drawn in the current BorderColor. When the
border is not highlighted, it will be stippled with an gray pattern using the current
BorderTileForeground and BorderTileBackground colors.
NoIconTitle [{ win-list }]
This variable indicates that icons should not display the icon name of the client. If the
optional win-list is given, only those clients will not have icon titles.
NoIconManagerFocus
This variable indicates that ctwm will not set the focus on the corresponding window when the
pointer is in an IconManager.
NoIconManagers
This variable indicates that no icon manager should be created.
NoImagesInWorkSpaceManager
This variable turns off displaying of background images in the WorkSpaceMap. Instead only the
colors defined in WorkSpaces will be used as background in the WorkSpaceMap.
NoMenuShadows
This variable indicates that menus should not have drop shadows drawn behind them. This is
typically used with slower servers since it speeds up menu drawing at the expense of making the
menu slightly harder to read.
NoOpaqueMove { window-list }
The counterpart of OpaqueMove. See OpaqueMove.
NoOpaqueResize { window-list }
The counterpart of OpaqueResize. See OpaqueResize.
NoRaiseOnDeiconify
This variable indicates that windows that are deiconified should not be raised.
NoRaiseOnMove
This variable indicates that windows should not be raised when moved. This is typically used to
allow windows to slide underneath each other.
NoRaiseOnResize
This variable indicates that windows should not be raised when resized. This is typically used
to allow windows to be resized underneath each other.
NoRaiseOnWarp
This variable indicates that windows should not be raised when the pointer is warped into them
with the f.warpto function. If this option is set, warping to an occluded window may result in
the pointer ending up in the occluding window instead the desired window (which causes unexpected
behavior with f.warpring).
NoSaveUnders
This variable indicates that menus should not request save-unders to minimize window repainting
following menu selection. It is typically used with displays that can repaint faster than they
can handle save-unders.
NoShowOccupyAll
This variable specifies that OccupyAll windows won't be displayed in the WorkSpaceMap window.
NoStackMode [{ win-list }]
This variable indicates that client window requests to change stacking order should be ignored.
If the optional win-list is given, only requests on those windows will be ignored. This is
typically used to prevent applications from relentlessly popping themselves to the front of the
window stack.
NoTitle [{ win-list }]
This variable indicates that windows should not have titlebars. If the optional win-list is
given, only those windows will not have titlebars. MakeTitle may be used with this option to
force titlebars to be put on specific windows.
NoTitleFocus
This variable indicates that ctwm should not set keyboard input focus to each window as it is
entered. Normally, ctwm sets the focus so that focus and key events from the titlebar and icon
managers are delivered to the application. If the pointer is moved quickly and ctwm is slow to
respond, input can be directed to the old window instead of the new. This option is typically
used to prevent this ‘input lag’ and to work around bugs in older applications that have problems
with focus events.
NoTitleHighlight [{ win-list }]
This variable indicates that the highlight area of the titlebar, which is used to indicate the
window that currently has the input focus, should not be displayed. If the optional win-list is
given, only those windows will not have highlight areas. This and the SqueezeTitle options can
be set to substantially reduce the amount of screen space required by titlebars.
NoWarpToMenuTitle
This variable indicates that the cursor should not be warped to the title of a menu which does
not have room to drop down below the current cursor position.
Occupy { occupy-list }
This variable specifies which windows occupy which workspaces at startup.
occupy-list consists of entries of the form :
[Window] win-name { wpsc1 wspc2 ... }
or Workspace wspc-name {win1 win2 ... }
Example :
Occupy {
"xload" {"all"}
Window "xterm" {"here" "there" "elsewhere"}
"xv" {"images"}
WorkSpace "images" {"xloadimage"}
}
Note : The Occupy declaration should come after the WorkSpaces declaration.
OccupyAll { window-list }
This variable specifies a list of windows that will occupy all workspaces at startup.
window-list is a list of window names.
Example :
OccupyAll
{
"xload"
"xbiff"
"xconsole"
}
Note : The OccupyAll declaration should come after the WorkSpaces declaration.
OpaqueMove { window-list }
This variable indicates that the f.move function should actually move the window instead of just
an outline so that the user can immediately see what the window will look like in the new
position. This option is typically used on fast displays (particularly if NoGrabServer is set).
The optional window list parameter indicates that only windows in this list should actually be
moved in opaque mode. The NoOpaqueMove counterpart is also available.
OpaqueMoveThreshold { threshold }
The integer parameter is a percentage and indicates that only windows (elligible for opaque
moving) with a surface smaller than this percentage of the surface of the screen should actually
be moved in opaque mode.
OpaqueResize { window-list }
The opaque version of resize. Extremely resource intensive, but beautiful with fast
server/client/network. See OpaqueMove. The NoOpaqueResize counterpart is also available.
OpaqueResizeThreshold { threshold }
The resize version of OpaqueMoveThreshold.
OpenWindowTimeout seconds
seconds is an integer representing a number of second. When a window tries to open on an
unattended display, it will be automatically mapped after this number of seconds.
PackNewWindows
Use f.movepack algorithm instead of f.move when opening a new window.
Pixmaps { pixmaps }
This variable specifies a list of pixmaps that define the appearance of various images. Each
entry is a keyword indicating the pixmap to set, followed by a string giving the name of the
bitmap file. The following pixmaps may be specified:
Pixmaps
{
TitleHighlight "gray1"
}
The default for TitleHighlight is to use an even stipple pattern.
PixmapDirectory path
This variable specifies the path where ctwm looks to find non-X11 bitmap files. Whenever you
want to use a image file that is not an X11 bitmap, specify : xpm:filename, for xpm files,
xwd:filename for xwd files, im:filename, for other files supported by the imconv package,
jpeg:file for jpeg file, or ‘|command’ for an on the fly generated xwd file. Use the % character
to specify an animation. path can be a colon separated list of directories. Example :
PixmapDirectory "/usr/lib/X11/twm"
Icons
{
"Axe" "xpm:edit.xpm"
"xterm" "xpm:ball%.xpm"
}
N.B This is only valid if your version of ctwm has been compiled with the right extension (XPM,
JPEG or IMCONV options).
RaiseDelay milliseconds
For windows that are to be automatically raised when the pointer enters (see the AutoRaise
variable and the f.autoraise function) this variable specifies the length of time the pointer
should rest in the window before it is raised. The default is 0 milliseconds.
RaiseOnClick
If present a window will be raised on top of others when clicked on, and the ButtonPress event
will be correctly forwarded to the client that owns this window (if it asked to). See
RaiseOnClickButton.
RaiseOnClickButton button_number
Where button_number is a valid button number (generally 1 to 3). Specify the button to use for
RaiseOnClick.
RaiseWhenAutoUnSqueeze
Windows are raised when auto-unsqueezed (See AutoSqueeze).
RandomPlacement [ string ]
Where string is either ‘on’, ‘off’, ‘all’ or ‘unmapped’. This variable indicates that windows
with no specified geometry should be placed in a pseudo-random location instead of having the
user drag out an outline. The argument ‘on’ or ‘all’ tells ctwm do do this for all such windows,
‘off’, not to do this, and ‘unmapped’, only for unmapped windows, e.g. iconified or not visible
in the current workspace.
ReallyMoveInWorkspaceManager
This keyword tells ctwm to move the actual window when the user is moving the small windows in
the WorkSpaceMap window. If not present the WorkSpaceMap can be used only to modify the
occupation of a window.
ResizeFont string
This variable specifies the font to be used for in the dimensions window when resizing windows.
The default is ‘fixed’.
RestartPreviousState
This variable indicates that ctwm should attempt to use the WM_STATE property on client windows
to tell which windows should be iconified and which should be left visible. This is typically
used to try to regenerate the state that the screen was in before the previous window manager was
shutdown.
ReverseCurrentWorkspace string
This variable tells ctwm to reverse the background and foreground colors in the small windows in
the workspace map for the current workspace.
SaveColor { colors-list }
This variable indicates a list of color assignments to be stored as pixel values in the root
window property _MIT_PRIORITY_COLORS. Clients may elect to preserve these values when installing
their own colormap. Note that use of this mechanism is a way for an application to avoid the
‘technicolor’ problem, whereby useful screen objects such as window borders and titlebars
disappear when a program's custom colors are installed by the window manager. For example:
SaveColor
{
BorderColor
TitleBackground
TitleForeground
"red"
"green"
"blue"
}
This would place on the root window 3 pixel values for borders and titlebars, as well as the
three color strings, all taken from the default colormap.
ShrinkIconTitles
A la Motif shrinking of icon titles, and expansion when mouse is inside icon. The old incorrect
spelling SchrinkIconTitles is also still accepted.
ShortAllWindowsMenus
Don't show WorkSpaceManager and IconManagers in the TwmWindows and TwmAllWindows menus.
ShowIconManager
This variable indicates that the icon manager window should be displayed when ctwm is started.
It can always be brought up using the f.showiconmgr function.
ShowWorkSpaceManager
This variable specifies that the WorkSpaceManager should be visible.
SloppyFocus
Use sloppy focus.
SortIconManager
This variable indicates that entries in the icon manager should be sorted alphabetically rather
than by simply appending new windows to the end.
SoundHost
The host on which sounds should be played. See the SOUNDS section.
SqueezeTitle [{ squeeze-list }]
This variable indicates that ctwm should attempt to use the SHAPE extension to make titlebars
occupy only as much screen space as they need, rather than extending all the way across the top
of the window. The optional squeeze-list may be used to control the location of the squeezed
titlebar along the top of the window. It contains entries of the form:
"name" justification num denom
where name is a window name, justification is either left, center, or right, and num and denom
are numbers specifying a ratio giving the relative position about which the titlebar is
justified. The ratio is measured from left to right if the numerator is positive, and right to
left if negative. A denominator of 0 indicates that the numerator should be measured in pixels.
For convenience, the ratio 0/0 is the same as 1/2 for center and -1/1 for right. For example:
SqueezeTitle
{
"XTerm" left 0 0
"xterm1" left 1 3
"xterm2" left 2 3
"oclock" center 0 0
"emacs" right 0 0
}
The DontSqueezeTitle list can be used to turn off squeezing on certain titles.
StartIconified [{ win-list }]
This variable indicates that client windows should initially be left as icons until explicitly
deiconified by the user. If the optional win-list is given, only those windows will be started
iconic. This is useful for programs that do not support an -iconic command line option or
resource.
StartInMapState
This variable specifies that the WorkSpaceManager should be started in its map form when created.
StartSqueezed { win-list }
These windows will first show up squeezed (see f.squeeze).
StayUpMenus
Tells ctwm to use stayup menus. These menus will stay on the screen when ButtonUp, if either the
menu has not yet been entered by the pointer, or the current item is a f.title.
SunkFocusWindowTitle
This variable specifies that the title of the focus window (if exists) should be sunken instead
of raised. Only valid if UseThreeDTitles is set.
ThreeDBorderWidth pixels
The width of the 3D border in pixels, if any.
TitleBackground string [{ win-list }]
This variable specifies the background color used in titlebars, and may only be specified inside
of a Color or Monochrome list. The optional win-list is a list of window names and colors so
that per-window colors may be specified. The default is ‘white’.
TitleButtonBorderWidth pixels
This variable specifies the width in pixels of the border surrounding titlebuttons. This is
typically set to 0 to allow titlebuttons to take up as much space as possible and to not have a
border. The default is 1 if UseThreeDTitles is not set, 0 if it is set.
TitleButtonShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses for 3D title buttons, when
UseThreeDTitles is selected.
TitleFont string
This variable specifies the font used for displaying window names in titlebars. The default is
‘variable’.
TitleForeground string [{ win-list }]
This variable specifies the foreground color used in titlebars, and may only be specified inside
of a Color or Monochrome list. The optional win-list is a list of window names and colors so
that per-window colors may be specified. The default is ‘black’.
TitleJustification string
This keyword needs a string value. The acceptable values are : ‘left’, ‘center’ and ‘right’. The
window titles will be justified according to this in the title window.
TitlePadding pixels
This variable specifies the distance between the various buttons, text, and highlight areas in
the titlebar. The default is 8 pixels if UseThreeDTitles is not set, 0 if it is set.
TitleShadowDepth pixels
This variable specifies the depth of the shadow ctwm uses for 3D titles, when UseThreeDTitles is
selected.
TransientHasOccupation
This variable specifies that transient-for and non-group leader windows can have their own
occupation potentially different from their leader window. The default case is that these windows
follow their leader, use this keyword if the default action doesn't please you.
TransientOnTop percentage
The parameter (required) is a percentage and tells ctwm to put transient (and non-group leader)
windows always on top of their leader if and only if their surface is smaller than this fraction
of the surface of their leader. The surface of a window is its width times its weight.
UnknownIcon string
This variable specifies the filename of a bitmap file to be used as the default icon. This
bitmap will be used as the icon of all clients which do not provide an icon bitmap and are not
listed in the Icons list.
UnmapByMovingFarAway [{ win-list }]
These windows will be moved out of the screen instead of being unmapped when they become
invisible due to a change workspace. This has been added because some ill-behaved clients
(Frame5) don't like to be unmapped.
UsePPosition string
This variable specifies whether or not ctwm should honor program-requested locations (given by
the PPosition flag in the WM_NORMAL_HINTS property) in the absence of a user-specified position.
The argument string may have one of three values: "off" (the default) indicating that ctwm
should ignore the program-supplied position, "on" indicating that the position should be used,
and "non-zero" indicating that the position should used if it is other than (0,0). The latter
option is for working around a bug in older toolkits.
UseSunkTitlePixmap
This makes it so the shadows are inversed for title pixmaps when focus is lost. This is similar
to having the SunkFocusWindowTitle, but it makes your xbm or 3d XPM (if any) sink instead of just
the whole bar.
UseThreeDBorders
Tells ctwm to use 3D-looking window borders. The width ot the 3D borders is ThreeDBorderWidth.
The color of the 3D border is BorderTileBackground, and if NoHighlight is not selected, the
border of the Focus window is BorderColor.
UseThreeDIconManagers
Tells ctwm to use 3D-looking IconManagers if any.
UseThreeDMenus
Tells ctwm to use 3D-looking menus.
UseThreeDTitles
Tells ctwm to use 3D-looking windows titles. In which case the default values of
TitleButtonBorderWidth, FramePadding, TitlePadding and ButtonIndent are set to 0. There are
plenty of built-in scalable pixmaps for buttons, :xpm:menu, :xpm:dot, :xpm:cross, :xpm:bar,
:xpm:vbar, :xpm:iconify, :xpm:resize, :xmp:sunkresize and :xpm:box. There are several built-in
scalable animations for buttons : %xpm:resize, %xpm:menu-up, %xpm:menu-down, %xpm:resize-out-top,
%xpm:resize-in-top, %xpm:resize-out-bot, %xpm:resize-in-bot, %xpm:maze-out, %xpm:maze-in,
%xpm:zoom-out, %xpm:zoom-in and %xpm:zoom-inout. Try them to see what they look like.
UseThreeDWMap
Tells ctwm to use 3D for the small windows in the workspace map.
VirtualScreens { geometries-list }
This variable specifies a list of geometries for virtual screens. Virtual screens are designed to
be used when you have several physical screens bound together with the Xinerama X extension.
geometries-list is a list of valid geometry strings, that correspond to your actual physical
screens.
Example :
VirtualScreens
{
"1280x1024+0+0"
"1600x1200+1280+0"
}
WarpCursor [{ win-list }]
This variable indicates that the pointer should be warped into windows when they are deiconified.
If the optional win-list is given, the pointer will only be warped when those windows are
deiconified.
WindowBox [{ win-list }]
creates a new window called a box, where all the client windows that match the windows list are
opened in, instead of the root window. This is useful to group small windows in the same box
(xload for instance)
WindowBox "xloadbox" "320x100+0-0" {
"xload"
}
WindowGeometries [{ win-list }]
Used to give a default geometry to some clients :
WindowGeometries {
"Mozilla*" "1000x800+10+10"
"jpilot*" "800x600-0-0"
}
WindowRing [{ win-list }]
This variable specifies a list of windows along which the f.warpring function cycles. If no
argument is given, all the windows are in the ring.
WarpRingOnScreen
Tells ctwm that f.warpring warps pointer only to windows visible in the current workspace.
WarpToDefaultMenuEntry
(Useful only with StayUpMenus) When using StayUpMenus, and a menu does stays up, the pointer is
warped to the default entry of the menu.
WarpUnmapped
This variable indicates that that the f.warpto function should deiconify any iconified windows it
encounters. This is typically used to make a key binding that will pop a particular window (such
as xmh), no matter where it is. The default is for f.warpto to ignore iconified windows.
WindowRingExclude [{ win-list }]
All listed windows will be excluded from the WarpRing.
WMgrButtonShadowDepth depth
Control the depth of the shadow of the workspace manager buttons.
WMgrHorizButtonIndent nb_pixels
Specifies the horizontal space, in pixel, between the buttons of the workspace manager (in button
mode).
WMgrVertButtonIndent nb_pixels
Specifies the vertical space, in pixel, between the buttons of the workspace manager (in button
mode).
WorkSpaceFont string
This allows you to specify the font to use for the small windows in the workspace manager map.
(Try ‘-adobe-times-*-r-*--10-*-*-*-*-*-*-*’).
WorkSpaceManagerGeometry string [ columns ]
This variable specifies the geometry of the workspace manager window. The string argument is
standard geometry specification that indicates the initial full size of the workspace manager.
The columns argument indicates the number of columns to use for the workspace manager window.
WorkSpaceManagerGeometry "360x60+60-0" 8
WorkSpaces { workspace-list }
This variable specifies a list of workspaces that are created at startup, Where workspace-list is
:
name [{bg-button [fg-button] [bg-root] [fg-root] [pixmap-root]}]
With :
bg-button:
background color of the corresponding button in the workspace manager.
fg-button:
foreground color of the corresponding button in the workspace manager.
bg-root:
background color of the corresponding root screen.
fg-root:
foreground color of the corresponding root screen.
pixmap-root:
pixmap to display on the corresponding root screen, either the name of a bitmap,
xpm:xpmfile, xwd:xwdfile, jpeg:jpgfile, im:imfile or |command_that generate_xwd.
Example :
WorkSpaces
{
"One" {"#686B9F" "white" "DeepSkyBlue3" "white" "jpeg:shark.jpg"}
"Two" {"#619AAE" "white" "firebrick"}
"Three" {"#727786" "white" "MidnightBlue" "white" "xpm:ball%.xpm"}

"Five" {"#727786" "white" "DeepSkyBlue3" "white" "plaid"}
"Six" {"#619AAE" "white" "DeepSkyBlue3" "white" "xpm:background1"}
"Seven" {"#8C5b7A" "white" "chartreuse4"}
"Eight" {"#686B9F" "white" "MidnightBlue"}
}
The WorkSpaces declaration should come before the Occupy or OccupyAll declarations. The maximum
number of workspaces is 32.
XMoveGrid number
This variable specifies the value to use to constrain window movement. When moving windows
around, the x coordinate will always be a multiple of this variable. Default is 1. f.forcemove
ignores this variable.
XorValue number
This variable specifies the value to use when drawing window outlines for moving and resizing.
This should be set to a value that will result in a variety of distinguishable colors when
exclusive-or'ed with the contents of the user's typical screen. Setting this variable to 1 often
gives nice results if adjacent colors in the default colormap are distinct. By default, ctwm
will attempt to cause temporary lines to appear at the opposite end of the colormap from the
graphics.
YMoveGrid number
This variable specifies the value to use to constrain window movement. When moving windows
around, the y coordinate will always be a multiple of this variable. Default is 1. f.forcemove
ignores this variable.
Zoom [ count ]
This variable indicates that outlines suggesting movement of a window to and from its iconified
state should be displayed whenever a window is iconified or deiconified. The optional count
argument specifies the number of outlines to be drawn. The default count is 8.
The following variables must be set after the fonts have been assigned, so it is usually best to put them
at the end of the variables or beginning of the bindings sections:
ChangeWorkspaceFunction function
This variable specifies the function to be executed when the user change the current workspace
(zap).
DefaultFunction function
This variable specifies the function to be executed when a key or button event is received for
which no binding is provided. This is typically bound to f.nop, f.beep, or a menu containing
window operations.
DeIconifyFunction function
This variable specifies the function to be executed when a window is deiconified.
IconifyFunction function
This variable specifies the function to be executed when a window is iconified.
WindowFunction function
This variable specifies the function to execute when a window is selected from the TwmWindows
menu. If this variable is not set, the window will be deiconified and raised.
BINDINGS
After the desired variables have been set, functions may be attached to titlebuttons and key and pointer
buttons. Titlebuttons may be added from the left or right side and appear in the titlebar from
left-to-right according to the order in which they are specified. Key and pointer button bindings may be
given in any order.
Titlebuttons specifications must include the name of the pixmap to use in the button box and the function
to be invoked when a pointer button is pressed within them:
LeftTitleButton "bitmapname" = function
or
LeftTitleButton "bitmapname" {
Buttoni : function
...
Buttonj : function
}
or
RightTitleButton "bitmapname" = function
or
RightTitleButton "bitmapname" {
Buttoni : function
...
Buttonj : function
}
The bitmapname may refer to one of the built-in bitmaps (which are scaled to match TitleFont) by using
the appropriate colon-prefixed name described above.
Key and pointer button specifications must give the modifiers that must be pressed, over which parts of
the screen the pointer must be, and what function is to be invoked. Keys are given as strings containing
the appropriate keysym name; buttons are given as the keywords Button1-Button5:
"FP1" = modlist : context : function
Button1 = modlist : context : function
The modlist is any combination of the modifier names shift, control, lock, meta, mod1, mod2, mod3, mod4,
or mod5 (which may be abbreviated as s, c, l, m, m1, m2, m3, m4, m5, respectively) separated by a
vertical bar (|). Similarly, the context is any combination of window, title, icon, root, frame,
workspace, iconmgr, their first letters (iconmgr abbreviation is m), or all, separated by a vertical bar.
The function is any of the f. keywords described below. For example, the default startup file contains
the following bindings:
Button1 = : root : f.menu "TwmWindows"
Button1 = m : window | icon : f.function "move-or-lower"
Button2 = m : window | icon : f.iconify
Button3 = m : window | icon : f.function "move-or-raise"
Button1 = : title : f.function "move-or-raise"
Button2 = : title : f.raiselower
Button1 = : icon : f.function "move-or-iconify"
Button2 = : icon : f.iconify
Button1 = : iconmgr : f.iconify
Button2 = : iconmgr : f.iconify
A user who wanted to be able to manipulate windows from the keyboard could use the following bindings:
"F1" = : all : f.iconify
"F2" = : all : f.raiselower
"F3" = : all : f.warpring "next"
"F4" = : all : f.warpto "xmh"
"F5" = : all : f.warpto "emacs"
"F6" = : all : f.colormap "next"
"F7" = : all : f.colormap "default"
"F20" = : all : f.warptoscreen "next"
"Left" = m : all : f.backiconmgr
"Right" = m | s : all : f.forwiconmgr
"Up" = m : all : f.upiconmgr
"Down" = m | s : all : f.downiconmgr
ctwm provides many more window manipulation primitives than can be conveniently stored in a titlebar,
menu, or set of key bindings. Although a small set of defaults are supplied (unless the NoDefaults is
specified), most users will want to have their most common operations bound to key and button strokes.
To do this, ctwm associates names with each of the primitives and provides user-defined functions for
building higher level primitives and menus for interactively selecting among groups of functions.
User-defined functions contain the name by which they are referenced in calls to f.function and a list of
other functions to execute. For example:
Function "move-or-lower" { f.move f.deltastop f.lower }
Function "move-or-raise" { f.move f.deltastop f.raise }
Function "move-or-iconify" { f.move f.deltastop f.iconify }
Function "restore-colormap" { f.colormap "default" f.lower }
The function name must be used in f.function exactly as it appears in the function specification.
In the descriptions below, if the function is said to operate on the selected window, but is invoked from
a root menu, the cursor will be changed to the Select cursor and the next window to receive a button
press will be chosen:
! string
This is an abbreviation for f.exec string.
f.addtoworkspace string
This function adds the selected window to the workspace whose name is string.
f.adoptwindow
This function asks for the user to select a window with the mouse, and then adopt this window if
it doesn't belong to the current ctwm. Useful only with the -w flag.
f.altcontext
Set the alternate context. The next key or button event ctwm reveives will be interpreted using
the alternate context. To define bindings in the alternate context, use the keyword alter in the
context field of the binding command. For example:
"Return"= m : all : f.altcontext
"n" = : alter : f.nextworkspace
"p" = : alter : f.prevworkspace
f.altkeymap number
Set the alternate keymap number, where number is an integer between 1 and 5 included. The next
key or button event ctwm reveives will be interpreted using this alternate keymap. To define
bindings in an alternate keymap, use the keyword a followed by number in the modifier field of
the binding command. For example:
"Return"= c : all : f.altkeymap "1"
"i" = a1 : window|icon|iconmgr : f.iconify
"z" = a1 : window : f.zoom
"d" = a1 : window|icon : f.delete
"o" = a1 : window|icon : f.occupy
"r" = a1 : window|icon : f.refresh
When using an alternate keymaps, only the root, window, icon and iconmgr contexts are allowed.
f.autolower
This function toggles whether or not the selected window is lowered whenever the pointer leaves
it. See the description of the variable AutoLower.
f.autoraise
This function toggles whether or not the selected window is raised whenever entered by the
pointer. See the description of the variable AutoRaise.
f.backmapiconmgr
This function warps the pointer in the same manner as f.backiconmgr but only stops at windows
that are mapped.
f.backiconmgr
This function warps the pointer to the previous column in the current icon manager, wrapping back
to the previous row if necessary.
f.beep This function sounds the keyboard bell.
f.bottomzoom
This function is similar to the f.fullzoom function, but resizes the window to fill only the
bottom half of the screen.
f.changesize string
This function allows you to change the size of the focused window. The format of the string must
be either "<border> <+|-><sizechange>" (where border must be one of Top, Bottom, Left or Right)
or "<x size>x<y size>" (where the size is the requested new window size). The height of the
window can never be set/changed to less than the title height + 1 (or 1 if the window has no
title) and the width can never be set/changed to less than 1.
"Right" = c|s: all : f.changesize "right +10"
"Left" = c|s: all : f.changesize "right -10"
"Down" = c|s: all : f.changesize "bottom +10"
"Up" = c|s: all : f.changesize "bottom -10"
"F1" = c|s: all : f.changesize "640x480"
"F2" = c|s: all : f.changesize "800x600"
"F3" = c|s: all : f.changesize "1024x768"
f.circledown
This function lowers the top-most window that occludes another window.
f.circleup
This function raises the bottom-most window that is occluded by another window.
f.colormap string
This function rotates the colormaps (obtained from the WM_COLORMAP_WINDOWS property on the
window) that ctwm will display when the pointer is in this window. The argument string may have
one of the following values: "next", "prev", and "default". It should be noted here that in
general, the installed colormap is determined by keyboard focus. A pointer driven keyboard focus
will install a private colormap upon entry of the window owning the colormap. Using the click to
type model, private colormaps will not be installed until the user presses a mouse button on the
target window.
f.deiconify
This function deiconifies the selected window. If the window is not an icon, this function does
nothing.
f.delete
This function sends the WM_DELETE_WINDOW message to the selected window if the client application
has requested it through the WM_PROTOCOLS window property. The application is supposed to
respond to the message by removing the indicated window. If the window has not requested
WM_DELETE_WINDOW messages, the keyboard bell will be rung indicating that the user should choose
an alternative method. Note this is very different from f.destroy. The intent here is to delete
a single window, not necessarily the entire application.
f.deleteordestroy
First tries to delete the window (send it WM_DELETE_WINDOW message), or kills it, if the client
doesn't accept such message.
f.deltastop
This function allows a user-defined function to be aborted if the pointer has been moved more
than MoveDelta pixels. See the example definition given for Function "move-or-raise" at the
beginning of the section.
f.destroy
This function instructs the X server to close the display connection of the client that created
the selected window. This should only be used as a last resort for shutting down runaway
clients. See also f.delete.
f.downiconmgr
This function warps the pointer to the next row in the current icon manger, wrapping to the
beginning of the next column if necessary.
f.downworkspace
Goto the workspace immediately underneath the current workspace in the workspace manager. If the
current workspace is the bottom one, goto the top one in the same column. The result depends on
the layout of the workspace manager.
f.exec string
This function passes the argument string to /bin/sh for execution. In multiscreen mode, if
string starts a new X client without giving a display argument, the client will appear on the
screen from which this function was invoked. If the string ‘$currentworkspace’ is present inside
the string argument, it will be substituted with the current workspace name.
f.fill string
Where string is either : ‘right’, ‘left’, ‘top’, ‘bottom’ or ‘vertical’. The current window is
resized in the specified direction until it reaches an obstacle (either another window, or the
screen border). f.fill ‘vertical’ sets the window status to ‘zoomed’ and toggles, ie calling it
again will reset the previous window size.
f.fittocontent
Can be used only with window boxes. The result is to have the box have the minimal size that
contains all its children windows.
f.focus This function toggles the keyboard focus of the server to the selected window, changing the focus
rule from pointer-driven if necessary. If the selected window already was focused, this function
executes an f.unfocus.
f.forcemove
This function is like f.move except that it ignores the DontMoveOff variable.
f.forwiconmgr
This function warps the pointer to the next column in the current icon manager, wrapping to the
beginning of the next row if necessary.
f.forwmapiconmgr
This function warps the pointer in the same manner as f.forwiconmgr but only stops at windows
that are mapped.
f.fullzoom
This function resizes the selected window to the full size of the display or else restores the
original size if the window was already zoomed.
f.function string
This function executes the user-defined function whose name is specified by the argument string.
f.gotoworkspace workspace_name
This function warps you to the workspace whose name is workspace_name.
f.hbzoom
This function is a synonym for f.bottomzoom.
f.hideiconmgr
This function unmaps the current icon manager.
f.hideworkspacemgr
Unmap the WorkSpace manager.
f.horizoom
This variable is similar to the f.zoom function except that the selected window is resized to the
full width of the display.
f.htzoom
This function is a synonym for f.topzoom.
f.hypermove
Use this function to ‘move’ a window between 2 captives ctwm (or between a captive and the root
ctwm). Of course 2 ctwms are completely different universes. You have to go in hyperspace to
achieve this, hence the name.
f.hzoom This function is a synonym for f.horizoom.
f.iconify
This function iconifies or deiconifies the selected window or icon, respectively.
f.identify
This function displays a summary of the name and geometry of the selected window. Clicking the
pointer or pressing a key in the window will dismiss it.
f.initsize
This function resets a window to its initial size given by the WM_NORMAL_HINTS hints.
f.jumpdown step
This function is designed to be bound to a key, it moves the current window (step *
{X,Y}MoveGrid) pixels downward. stopping if the window encounters another window or the screen
border (ala f.pack).
f.jumpleft step
Leftward equivalent of f.jumpdown.
f.jumpright step
Rightward equivalent of f.jumpdown.
f.jumpup step
Upward equivalent of f.jumpdown.
f.lefticonmgr
This function similar to f.backiconmgr except that wrapping does not change rows.
f.leftworkspace
Goto the workspace immediately on the left of the current workspace in the workspace manager. If
the current workspace is the leftest one, goto the rightest one in the same row. The result
depends on the layout of the workspace manager.
f.leftzoom
This variable is similar to the f.bottomzoom function but causes the selected window is only
resized to the left half of the display.
f.lower This function lowers the selected window.
f.menu string
This function invokes the menu specified by the argument string. Cascaded menus may be built by
nesting calls to f.menu. When a menu is popped up, you can use the arrow keys to move the cursor
around it. ‘Down’ or space goes down, ‘Up’ goes up, ‘Left’ pops down the menu, and ‘Right’
activates the current entry. The first letter of an entry name activates this entry (the first
one if several entries match). If the first letter is ~ then Meta-the-second-letter activates it,
if this first letter is ^ then Control-the-second-letter activates it, and if this first letter
is space, then the second letter activates it.
f.move This function drags an outline of the selected window (or the window itself if the OpaqueMove
variable is set) until the invoking pointer button is released. Double clicking within the
number of milliseconds given by ConstrainedMoveTime warps the pointer to the center of the window
and constrains the move to be either horizontal or vertical depending on which grid line is
crossed. To abort a move, press another button before releasing the first button.
f.movepack
This function is like f.move except that it tries to avoid overlapping of windows. When the
moving window begin to overlap with another window, the move is stopped. If you go too far over
the other window (more that MovePackResistance pixels), the move is resumed and the moving window
can overlap with the other window. Useful to pack windows closely.
f.movepush
This function is like f.move except that it tries to avoid overlapping of windows. When the
moving window begins to overlap with another window, the other window is pushed. If you go too
far over the other window (more that MovePackResistance pixels), there is no push and the moving
window can overlap with the other window. Only available if OpaqueMove is active.
f.moveresize geometry
Takes one string argument which is a geometry with the standard X geometry syntax (e.g.
200x300+150-0). Sets the current window to the specified geometry. The width and height are to be
given in pixel, no base size or resize increment are used.
f.movetonextworkspace
Move the window to the next workspace.
f.movetoprevworkspace
Move the window to the previous workspace.
f.movetonextworkspaceandfollow
Move the window to the next workspace and go to that workspace.
f.movetoprevworkspaceandfollow
Move the window to the previous workspace and go to that workspace.
f.nexticonmgr
This function warps the pointer to the next icon manager containing any windows on the current or
any succeeding screen.
f.nextworkspace
Goto the next workspace in the list, using the order given in the .ctwmrc file.
f.nop This function does nothing and is typically used with the DefaultFunction or WindowFunction
variables or to introduce blank lines in menus.
f.occupy
This function pops up a window for the user to choose which workspaces a window belongs to.
f.occupyall
This function makes the specified window occupy all the workspaces.
f.pack string
Where string is either : ‘right’, ‘left’, ‘top’ or ‘bottom’ The current window is moved in the
specified direction until it reaches an obstacle (either another window, or the screen border).
The pointer follows the window.
f.previconmgr
This function warps the pointer to the previous icon manager containing any windows on the
current or preceding screens.
f.prevworkspace
Goto the previous workspace in the list, using the order given in the .ctwmrc file.
f.pin Valid only in a root menu. Make a menu permanent on the screen. This is a toggle function, if you
select it while the menu is already permanent, it becomes non-permanent.
f.quit This function causes ctwm to restore the window's borders and exit. If ctwm is the first client
invoked from xdm, this will result in a server reset.
f.raiseicons
This function raises all the icons in the current workspace.
f.raise This function raises the selected window.
f.raiselower
This function raises the selected window to the top of the stacking order if it is occluded by
any windows, otherwise the window will be lowered.
f.removefromworkspace string
This function removes the selected window from the workspace whose name is string.
f.refresh
This function causes all windows to be refreshed.
f.rereadsounds
This function causes the .ctwm-sounds file to be re-read. See the SOUNDS section.
f.resize
This function displays an outline of the selected window. Crossing a border (or setting
AutoRelativeResize) will cause the outline to begin to rubber band until the invoking button is
released. To abort a resize, press another button before releasing the first button.
f.restart
This function kills and restarts ctwm.
f.restoregeometry
Restore the current window geometry to what was saved in the last call to f.savegeometry.
f.righticonmgr
This function is similar to f.nexticonmgr except that wrapping does not change rows.
f.rightworkspace
Goto the workspace immediately on the right of the current workspace in the workspace manager. If
the current workspace is the rightest one, goto the leftest one in the same row. The result
depends on the layout of the workspace manager.
f.rightzoom
This variable is similar to the f.bottomzoom function except that the selected window is only
resized to the right half of the display.
f.ring Selects a window and adds it to the WarpRing, or removes it if it was already in the ring. This
command makes f.warpring much more useful, by making its configuration dynamic.
f.savegeometry
The geometry of the current window is saved. The next call to f.restoregeometry will restore this
window to this geometry.
f.saveyourself
This function sends a WM_SAVEYOURSELF message to the selected window if it has requested the
message in its WM_PROTOCOLS window property. Clients that accept this message are supposed to
checkpoint all state associated with the window and update the WM_COMMAND property as specified
in the ICCCM. If the selected window has not selected for this message, the keyboard bell will
be rung.
f.separator
Valid only in menus. The effect is to add a line separator between the previous and the following
entry. The name selector part in the menu is not used (but must be present).
f.setbuttonsstate
Set the WorkSpace manager in button state.
f.setmapstate
Set the WorkSpace manager in map state.
f.showiconmgr
This function maps the current icon manager.
f.sorticonmgr
This function sorts the entries in the current icon manager alphabetically. See the variable
SortIconManager.
f.showbackground
This function unmaps all windows in the current workspace. This is a toggle function, if all
windows are unmapped, they are all remapped. Better bind this function in the root context.
f.showworkspacemgr
Map the WorkSpace manager.
f.slowdownanimation
Decrease AnimationSpeed by 1.
f.speedupanimation
Increase AnimationSpeed by 1.
f.squeeze
f.squeeze squeezes a window to a null vertical size. Works only for windows with either a title,
or a 3D border (in order to have something left on the screen). If the window is already
squeezed, it is unsqueezed.
f.startanimation
Restart freezed animations (if any).
f.stopanimation
Freeze animations (if any).
f.title This function provides a centered, unselectable item in a menu definition. It should not be used
in any other context.
f.toggleoccupation string
This function adds the selected window to the workspace whose name is string if it doesn't
already belongs to it, and removes it from this workspace if not.
f.togglesound
Toggle sound on/off. See the SOUNDS section.
f.togglestate
Toggle the state of the WorkSpace manager.
f.toggleworkspacemgr
Toggle the presence of the WorkSpaceManager. If it is mapped, it will be unmapped and vice versa.
f.topzoom
This variable is similar to the f.bottomzoom function except that the selected window is only
resized to the top half of the display.
f.unfocus
This function resets the focus back to pointer-driven. This should be used when a focused window
is no longer desired.
f.upiconmgr
This function warps the pointer to the previous row in the current icon manager, wrapping to the
last row in the same column if necessary.
f.upworkspace
Goto the workspace immediately above the current workspace in the workspace manager. If the
current workspace is the top one, goto the bottom one in the same column. The result depends on
the layout of the workspace manager.
f.vanish
The specified window vanishes from the current workspace if it occupies at least one other
WorkSpace. Do nothing in the others cases.
f.vlzoom
This function is a synonym for f.leftzoom.
f.vrzoom
This function is a synonym for f.rightzoom.
f.warphere win_name
This function adds the window which has a name or class that matches string to the current
workspace and warps the pointer to it. If the window is iconified, it will be deiconified if the
variable WarpUnmapped is set or else ignored.
f.warpring string
This function warps the pointer to the next or previous window (as indicated by the argument
string, which may be "next" or "prev") specified in the WindowRing variable.
f.warpto string
This function warps the pointer to the window which has a name or class that matches string. If
the window is iconified, it will be deiconified if the variable WarpUnmapped is set or else
ignored.
f.warptoiconmgr string
This function warps the pointer to the icon manager entry associated with the window containing
the pointer in the icon manager specified by the argument string. If string is empty (i.e. ""),
the current icon manager is chosen.
f.warptoscreen string
This function warps the pointer to the screen specified by the argument string. String may be a
number (e.g. "0" or "1"), the word "next" (indicating the current screen plus 1, skipping over
any unmanaged screens), the word "back" (indicating the current screen minus 1, skipping over any
unmanaged screens), or the word "prev" (indicating the last screen visited.
f.winrefresh
This function is similar to the f.refresh function except that only the selected window is
refreshed.
f.zoom This function is similar to the f.fullzoom function, except that the only the height of the
selected window is changed.
MENUS
Functions may be grouped and interactively selected using pop-up (when bound to a pointer button) or
pull-down (when associated with a titlebutton) menus. Each menu specification contains the name of the
menu as it will be referred to by f.menu, optional default foreground and background colors, the list of
item names and the functions they should invoke, and optional foreground and background colors for
individual items:
Menu "menuname" [ ("deffore":"defback") ]
{
string1 [ ("fore1":"backn")] function1
string2 [ ("fore2":"backn")] function2
.
.
.
stringN [ ("foreN":"backN")] functionN
}
The menuname is case-sensitive. The optional deffore and defback arguments specify the foreground and
background colors used on a color display to highlight menu entries. The string portion of each menu
entry will be the text which will appear in the menu. The optional fore and back arguments specify the
foreground and background colors of the menu entry when the pointer is not in the entry. These colors
will only be used on a color display. The default is to use the colors specified by the MenuForeground
and MenuBackground variables. The function portion of the menu entry is one of the functions, including
any user-defined functions, or additional menus.
There are 3 special menus. TwmWindows contains the names of all of the client and ctwm-supplied windows
in the current workspace. Selecting an entry will cause the WindowFunction to be executed on that
window. If WindowFunction hasn't been set, the window will be deiconified and raised. TwmWorkspaces
contains the names of your workspaces, selecting an entry goto this workspace. In addition, these entries
have submenus containing the names of all windows occupying this workspace, selecting such an entry
executes f.warpto on this window. And finally, TwmAllWindows contains the names of all the windows ctwm
manages. Selecting an entry executes f.warpto on this window.
If an entry name begins with a ‘*’ (star), this star won't be displayed and the corresponding entry will
be the default entry for this menu. When a menu has a default entry and is used as a submenu of another
menu, this default entry action will be executed automatically when this submenu is selected without
being displayed. It's hard to explain, but easy to understand.
ICONS
ctwm supports several different ways of manipulating iconified windows. The common pixmap-and-text style
may be laid out by hand or automatically arranged as described by the IconRegion variable. In addition,
a terse grid of icon names, called an icon manager, provides a more efficient use of screen space as well
as the ability to navigate among windows from the keyboard.
An icon manager is a window that contains names of selected or all windows currently on the display. In
addition to the window name, a small button using the default iconify symbol will be displayed to the
left of the name when the window is iconified. By default, clicking on an entry in the icon manager
performs f.iconify. To change the actions taken in the icon manager, use the the iconmgr context when
specifying button and keyboard bindings.
Moving the pointer into the icon manager also directs keyboard focus to the indicated window (setting the
focus explicitly or else sending synthetic events NoTitleFocus is set). Using the f.upiconmgr,
f.downiconmgr f.lefticonmgr, and f.righticonmgr functions, the input focus can be changed between windows
directly from the keyboard.
SOUNDS
If compiled with the USE_SOUND flag, ctwm is able to play sounds for any X event. ctwm will look for the
file .ctwm-sounds in the user's home directory to map every X event to a sound file to be played.
Each line in .ctwm-sounds has the following syntax:
{X event}: {sound file}
The currently known X events that can be given are:
KeyPress
KeyRelease
ButtonPress
ButtonRelease
MotionNotify
EnterNotify
LeaveNotify
FocusIn
FocusOut
KeymapNotify
Expose
GraphicsExpose
NoExpose
VisibilityNotify
CreateNotify
DestroyNotify
UnmapNotify
MapNotify
MapRequest
ReparentNotify
ConfigureNotify
ConfigureRequest
GravityNotify
ResizeRequest
CirculateNotify
CirculateRequest
PropertyNotify
SelectionClear
SelectionRequest
SelectionNotify
ColormapNotify
ClientMessage
MappingNotify
Additionally, the following two are recognised, and represent the time when ctwm is started or shut down:
Startup
Shutdown
BUGS
The resource manager should have been used instead of all of the window lists.
The IconRegion variable should take a list.
Double clicking very fast to get the constrained move function will sometimes cause the window to move,
even though the pointer is not moved.
If IconifyByUnmapping is on and windows are listed in IconManagerDontShow but not in
DontIconifyByUnmapping, they may be lost if they are iconified and no bindings to f.menu "TwmWindows" or
f.warpto are setup.
FILES
$HOME/.ctwmrc.<screen number>
$HOME/.ctwmrc

ENVIRONMENT VARIABLES
DISPLAY This variable is used to determine which X server to use. It is also set during f.exec so that
programs come up on the proper screen.
HOME This variable is used as the prefix for files that begin with a tilde and for locating the ctwm
startup file.
