Detailed Description
decoration object for a toplevel surface
The decoration object allows the compositor to toggle server-side window decorations for a toplevel
surface. The client can request to switch to another mode.
The xdg_toplevel_decoration object must be destroyed before its xdg_toplevel.

Member Enumeration Documentation
enum class wayland::proxy_t::wrapper_type [strong], [inherited]
Underlying wl_proxy type and properties of a proxy_t that affect construction, destruction, and event
handling
Enumerator
standard
C pointer is a standard type compatible with wl_proxy*. Events are dispatched and it is destructed
when the proxy_t is destructed. User data is set.
display
C pointer is a wl_display*. No events are dispatched, wl_display_disconnect is called when the
proxy_t is destructed. User data is set.
foreign
C pointer is a standard type compatible with wl_proxy*, but another library owns it and it should
not be touched in a way that could affect the operation of the other library. No events are
dispatched, wl_proxy_destroy is not called when the proxy_t is destructed, user data is not
touched. Consequently, there is no reference counting for the proxy_t. Lifetime of such wrappers
should preferably be short to minimize the chance that the owning library decides to destroy the
wl_proxy.
proxy_wrapper
C pointer is a wl_proxy* that was constructed with wl_proxy_create_wrapper. No events are
dispatched, wl_proxy_wrapper_destroy is called when the proxy_t is destroyed. Reference counting
is active. A reference to the proxy_t creating this proxy wrapper is held to extend its lifetime
until after the proxy wrapper is destroyed.

Member Function Documentation
wl_proxy * wayland::proxy_t::c_ptr () const [inherited]
Get a pointer to the underlying C struct.
Returns
The underlying wl_proxy wrapped by this proxy_t if it exists, otherwise an exception is thrown
std::string wayland::proxy_t::get_class () const [inherited]
Get the interface name (class) of a proxy object.
Returns
The interface name of the object associated with the proxy
uint32_t wayland::proxy_t::get_id () const [inherited]
Get the id of a proxy object.
Returns
The id the object associated with the proxy
uint32_t wayland::proxy_t::get_version () const [inherited]
Get the protocol object version of a proxy object. Gets the protocol object version of a proxy object, or
0 if the proxy was created with unversioned API.
A returned value of 0 means that no version information is available, so the caller must make safe
assumptions about the object's real version.
display_t will always return version 0.
Returns
The protocol object version of the proxy or 0
wrapper_type wayland::proxy_t::get_wrapper_type () const [inline], [inherited]
Get the type of a proxy object.

std::function< void(zxdg_toplevel_decoration_v1_mode)> & zxdg_toplevel_decoration_v1_t::on_configure ()
suggest a surface change
Parameters
mode the decoration mode
The configure event asks the client to change its decoration mode. The configured state should not be
applied immediately. Clients must send an ack_configure in response to this event. See
xdg_surface.configure and xdg_surface.ack_configure for details.
A configure event can be sent at any time. The specified mode must be obeyed by the client.
Definition at line 8908 of file wayland-client-protocol-unstable.cpp.
wayland::proxy_t::operator bool () const [inherited]
Check whether this wrapper actually wraps an object.
Returns
true if there is an underlying object, false if this wrapper is empty
bool wayland::proxy_t::operator!= (const proxy_t & right) const [inherited]
Check whether two wrappers refer to different objects.
bool wayland::proxy_t::operator== (const proxy_t & right) const [inherited]
Check whether two wrappers refer to the same object.
bool wayland::proxy_t::proxy_has_object () const [inherited]
Check whether this wrapper actually wraps an object.
Returns
true if there is an underlying object, false if this wrapper is empty
void wayland::proxy_t::proxy_release () [inherited]
Release the wrapped object (if any), making this an empty wrapper. Note that display_t instances cannot
be released this way. Attempts to do so are ignored.
Examples
foreign_display.cpp.
void zxdg_toplevel_decoration_v1_t::set_mode (zxdg_toplevel_decoration_v1_mode const & mode)
set the decoration mode
Parameters
mode the decoration mode
Set the toplevel surface decoration mode. This informs the compositor that the client prefers the
provided decoration mode.
After requesting a decoration mode, the compositor will respond by emitting an xdg_surface.configure
event. The client should then update its content, drawing it without decorations if the received mode is
server-side decorations. The client must also acknowledge the configure when committing the new content
(see xdg_surface.ack_configure).
The compositor can decide not to use the client's mode and enforce a different mode instead.
Clients whose decoration mode depend on the xdg_toplevel state may send a set_mode request in response to
an xdg_surface.configure event and wait for the next xdg_surface.configure event to prevent unwanted
state. Such clients are responsible for preventing configure loops and must make sure not to send
multiple successive set_mode requests with the same decoration mode.
Definition at line 8896 of file wayland-client-protocol-unstable.cpp.
void wayland::proxy_t::set_queue (event_queue_t queue) [inherited]
Assign a proxy to an event queue.
Parameters
queue The event queue that will handle this proxy
Assign proxy to event queue. Events coming from proxy will be queued in queue instead of the display's
main queue.
See also: display_t::dispatch_queue().
Examples
proxy_wrapper.cpp.
void zxdg_toplevel_decoration_v1_t::unset_mode ()
unset the decoration mode Unset the toplevel surface decoration mode. This informs the compositor that
the client doesn't prefer a particular decoration mode.
This request has the same semantics as set_mode.
