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.

voidzxdg_toplevel_v6_t::move(seat_tconst&seat,uint32_tserial)
start an interactive move
Parametersseat the wl_seat of the user event
serial the serial of the user event
Start an interactive, user-driven move of the surface.
This request must be used in response to some sort of user action like a button press, key press, or
touch down event. The passed serial is used to determine the type of interactive move (touch, pointer,
etc).
The server may ignore move requests depending on the state of the surface (e.g. fullscreen or maximized),
or if the passed serial is no longer valid.
If triggered, the surface will lose the focus of the device (wl_pointer, wl_touch, etc) used for the
move. It is up to the compositor to visually indicate that the move is taking place, such as updating a
pointer cursor, during the move. There is no guarantee that the device focus will return when the move is
completed.

std::function<void()>&zxdg_toplevel_v6_t::on_close()
surface wants to be closed The close event is sent by the compositor when the user wants the surface to
be closed. This should be equivalent to the user clicking the close button in client-side decorations, if
your application has any.
This is only a request that the user intends to close the window. The client may choose to ignore this
request, or show a dialog to ask the user to save their data, etc.

std::function<void(int32_t,int32_t,array_t)>&zxdg_toplevel_v6_t::on_configure()
suggest a surface change
Parameterswidthheightstates
This configure event asks the client to resize its toplevel surface or to change its state. The
configured state should not be applied immediately. See xdg_surface.configure for details.
The width and height arguments specify a hint to the window about how its surface should be resized in
window geometry coordinates. See set_window_geometry.
If the width or height arguments are zero, it means the client should decide its own window dimension.
This may happen when the compositor needs to configure the state of the surface but doesn't have any
information about any previous or expected dimension.
The states listed in the event specify how the width/height arguments should be interpreted, and possibly
how it should be drawn.
Clients must send an ack_configure in response to this event. See xdg_surface.configure and
xdg_surface.ack_configure for details.

wayland::proxy_t::operatorbool()const[inherited]
Check whether this wrapper actually wraps an object.
Returns
true if there is an underlying object, false if this wrapper is empty
boolwayland::proxy_t::operator!=(constproxy_t&right)const[inherited]
Check whether two wrappers refer to different objects.
boolwayland::proxy_t::operator==(constproxy_t&right)const[inherited]
Check whether two wrappers refer to the same object.
boolwayland::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
voidwayland::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.

voidzxdg_toplevel_v6_t::resize(seat_tconst&seat,uint32_tserial,zxdg_toplevel_v6_resize_edgeconst&edges)
start an interactive resize
Parametersseat the wl_seat of the user event
serial the serial of the user event
edges which edge or corner is being dragged
Start a user-driven, interactive resize of the surface.
This request must be used in response to some sort of user action like a button press, key press, or
touch down event. The passed serial is used to determine the type of interactive resize (touch, pointer,
etc).
The server may ignore resize requests depending on the state of the surface (e.g. fullscreen or
maximized).
If triggered, the client will receive configure events with the 'resize' state enum value and the
expected sizes. See the 'resize' enum value for more details about what is required. The client must also
acknowledge configure events using 'ack_configure'. After the resize is completed, the client will
receive another 'configure' event without the resize state.
If triggered, the surface also will lose the focus of the device (wl_pointer, wl_touch, etc) used for the
resize. It is up to the compositor to visually indicate that the resize is taking place, such as updating
a pointer cursor, during the resize. There is no guarantee that the device focus will return when the
resize is completed.
The edges parameter specifies how the surface should be resized, and is one of the values of the
resize_edge enum. The compositor may use this information to update the surface position for example when
dragging the top left corner. The compositor may also use this information to adapt its behavior, e.g.
choose an appropriate cursor image.

voidzxdg_toplevel_v6_t::set_app_id(std::stringconst&app_id)
set application ID
Parametersapp_id
Set an application identifier for the surface.
The app ID identifies the general class of applications to which the surface belongs. The compositor can
use this to group multiple surfaces together, or to determine how to launch a new application.
For D-Bus activatable applications, the app ID is used as the D-Bus service name.
The compositor shell will try to group application surfaces together by their app ID. As a best practice,
it is suggested to select app ID's that match the basename of the application's .desktop file. For
example, 'org.freedesktop.FooViewer' where the .desktop file is 'org.freedesktop.FooViewer.desktop'.
See the desktop-entry specification [0] for more details on application identifiers and how they relate
to well-known D-Bus names and .desktop files.

voidzxdg_toplevel_v6_t::set_fullscreen(output_tconst&output)
set the window as fullscreen on a monitor
Parametersoutput
Make the surface fullscreen.
You can specify an output that you would prefer to be fullscreen. If this value is NULL, it's up to the
compositor to choose which display will be used to map this surface.
If the surface doesn't cover the whole output, the compositor will position the surface in the center of
the output and compensate with black borders filling the rest of the output.

voidzxdg_toplevel_v6_t::set_max_size(int32_twidth,int32_theight)
set the maximum size
Parameterswidthheight
Set a maximum size for the window.
The client can specify a maximum size so that the compositor does not try to configure the window beyond
this size.
The width and height arguments are in window geometry coordinates. See xdg_surface.set_window_geometry.
Values set in this way are double-buffered. They will get applied on the next commit.
The compositor can use this information to allow or disallow different states like maximize or fullscreen
and draw accurate animations.
Similarly, a tiling window manager may use this information to place and resize client windows in a more
effective way.
The client should not rely on the compositor to obey the maximum size. The compositor may decide to
ignore the values set by the client and request a larger size.
If never set, or a value of zero in the request, means that the client has no expected maximum size in
the given dimension. As a result, a client wishing to reset the maximum size to an unspecified state can
use zero for width and height in the request.
Requesting a maximum size to be smaller than the minimum size of a surface is illegal and will result in
a protocol error.
The width and height must be greater than or equal to zero. Using strictly negative values for width and
height will result in a protocol error.

voidzxdg_toplevel_v6_t::set_maximized()
maximize the window Maximize the surface.
After requesting that the surface should be maximized, the compositor will respond by emitting a
configure event with the 'maximized' state and the required window geometry. The client should then
update its content, drawing it in a maximized state, i.e. without shadow or other decoration outside of
the window geometry. The client must also acknowledge the configure when committing the new content (see
ack_configure).
It is up to the compositor to decide how and where to maximize the surface, for example which output and
what region of the screen should be used.
If the surface was already maximized, the compositor will still emit a configure event with the
'maximized' state.
Definition at line 10024 of file wayland-client-protocol-unstable.cpp.
voidzxdg_toplevel_v6_t::set_min_size(int32_twidth,int32_theight)

this size.
The width and height arguments are in window geometry coordinates. See xdg_surface.set_window_geometry.
Values set in this way are double-buffered. They will get applied on the next commit.

voidzxdg_toplevel_v6_t::set_minimized()
set the window as minimized Request that the compositor minimize your surface. There is no way to know if
the surface is currently minimized, nor is there any way to unset minimization on this surface.
If you are looking to throttle redrawing when minimized, please instead use the wl_surface.frame event
for this, as this will also work with live previews on windows in Alt-Tab, Expose or similar compositor
features.

voidzxdg_toplevel_v6_t::set_parent(zxdg_toplevel_v6_tconst&parent)
set the parent of this surface
Parametersparent
Set the 'parent' of this surface. This window should be stacked above a parent. The parent surface must
be mapped as long as this surface is mapped.
Parent windows should be set on dialogs, toolboxes, or other 'auxiliary' surfaces, so that the parent is
raised when the dialog is raised.

voidwayland::proxy_t::set_queue(event_queue_tqueue)[inherited]
Assign a proxy to an event queue.
Parametersqueue 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().
Examplesproxy_wrapper.cpp.
voidzxdg_toplevel_v6_t::set_title(std::stringconst&title)
set surface title
Parameterstitle
Set a short title for the surface.
This string may be used to identify the surface in a task bar, window list, or other user interface
elements provided by the compositor.
The string must be encoded in UTF-8.

voidzxdg_toplevel_v6_t::show_window_menu(seat_tconst&seat,uint32_tserial,int32_tx,int32_ty)
show the window menu
Parametersseat the wl_seat of the user event
serial the serial of the user event
x the x position to pop up the window menu at
y the y position to pop up the window menu at
Clients implementing client-side decorations might want to show a context menu when right-clicking on the
decorations, giving the user a menu that they can use to maximize or minimize the window.
This request asks the compositor to pop up such a window menu at the given position, relative to the
local surface coordinates of the parent surface. There are no guarantees as to what menu items the window
menu contains.
This request must be used in response to some sort of user action like a button press, key press, or
touch down event.
Definition at line 9994 of file wayland-client-protocol-unstable.cpp.
voidzxdg_toplevel_v6_t::unset_maximized()
unmaximize the window Unmaximize the surface.
After requesting that the surface should be unmaximized, the compositor will respond by emitting a
configure event without the 'maximized' state. If available, the compositor will include the window
geometry dimensions the window had prior to being maximized in the configure request. The client must
then update its content, drawing it in a regular state, i.e. potentially with shadow, etc. The client
must also acknowledge the configure when committing the new content (see ack_configure).
It is up to the compositor to position the surface after it was unmaximized; usually the position the
surface had before maximizing, if applicable.
If the surface was already not maximized, the compositor will still emit a configure event without the
'maximized' state.
