Expand description
displays a single surface per output
Displays a single surface per output.
This interface provides a mechanism for a single client to display simple full-screen surfaces. While there technically may be multiple clients bound to this interface, only one of those clients should be shown at a time.
To present a surface, the client uses either the present_surface or present_surface_for_mode requests. Presenting a surface takes effect on the next wl_surface.commit. See the individual requests for details about scaling and mode switches.
The client can have at most one surface per output at any time. Requesting a surface to be presented on an output that already has a surface replaces the previously presented surface. Presenting a null surface removes its content and effectively disables the output. Exactly what happens when an output is “disabled” is compositor-specific. The same surface may be presented on multiple outputs simultaneously.
Once a surface is presented on an output, it stays on that output until either the client removes it or the compositor destroys the output. This way, the client can update the output’s contents by simply attaching a new buffer.
Warning! The protocol described in this file is experimental and backward incompatible changes may be made. Backward compatible changes may be added together with the corresponding interface version bump. Backward incompatible changes are done by bumping the version number in the protocol and interface names and resetting the interface version. Once the protocol is to be declared stable, the ‘z’ prefix and the version number in the protocol and interface names are removed and the interface version number is reset.
See also the Event enum for this interface.

Implementations§
source§impl ZwpFullscreenShellV1
impl ZwpFullscreenShellV1
sourcepub fn release(&self)
pub fn release(&self)
release the wl_fullscreen_shell interface
Release the binding from the wl_fullscreen_shell interface.
This destroys the server-side object and frees this binding. If the client binds to wl_fullscreen_shell multiple times, it may wish to free some of those bindings.
sourcepub fn present_surface(
&self,
surface: Option<&WlSurface>,
method: PresentMethod,
output: Option<&WlOutput>,
)
pub fn present_surface( &self, surface: Option<&WlSurface>, method: PresentMethod, output: Option<&WlOutput>, )
present surface for display
Present a surface on the given output.
If the output is null, the compositor will present the surface on whatever display (or displays) it thinks best. In particular, this may replace any or all surfaces currently presented so it should not be used in combination with placing surfaces on specific outputs.
The method parameter is a hint to the compositor for how the surface is to be presented. In particular, it tells the compositor how to handle a size mismatch between the presented surface and the output. The compositor is free to ignore this parameter.
The “zoom”, “zoom_crop”, and “stretch” methods imply a scaling operation on the surface. This will override any kind of output scaling, so the buffer_scale property of the surface is effectively ignored.
This request gives the surface the role of a fullscreen shell surface. If the surface already has another role, it raises a role protocol error.
sourcepub fn present_surface_for_mode<U: Send + Sync + 'static, D: Dispatch<ZwpFullscreenShellModeFeedbackV1, U> + 'static>(
&self,
surface: &WlSurface,
output: &WlOutput,
framerate: i32,
qh: &QueueHandle<D>,
udata: U,
) -> ZwpFullscreenShellModeFeedbackV1
pub fn present_surface_for_mode<U: Send + Sync + 'static, D: Dispatch<ZwpFullscreenShellModeFeedbackV1, U> + 'static>( &self, surface: &WlSurface, output: &WlOutput, framerate: i32, qh: &QueueHandle<D>, udata: U, ) -> ZwpFullscreenShellModeFeedbackV1
present surface for display at a particular mode
Presents a surface on the given output for a particular mode.
If the current size of the output differs from that of the surface, the compositor will attempt to change the size of the output to match the surface. The result of the mode-switch operation will be returned via the provided wl_fullscreen_shell_mode_feedback object.
If the current output mode matches the one requested or if the compositor successfully switches the mode to match the surface, then the mode_successful event will be sent and the output will contain the contents of the given surface. If the compositor cannot match the output size to the surface size, the mode_failed will be sent and the output will contain the contents of the previously presented surface (if any). If another surface is presented on the given output before either of these has a chance to happen, the present_cancelled event will be sent.
Due to race conditions and other issues unknown to the client, no mode-switch operation is guaranteed to succeed. However, if the mode is one advertised by wl_output.mode or if the compositor advertises the ARBITRARY_MODES capability, then the client should expect that the mode-switch operation will usually succeed.
If the size of the presented surface changes, the resulting output is undefined. The compositor may attempt to change the output mode to compensate. However, there is no guarantee that a suitable mode will be found and the client has no way to be notified of success or failure.
The framerate parameter specifies the desired framerate for the output in mHz. The compositor is free to ignore this parameter. A value of 0 indicates that the client has no preference.
If the value of wl_output.scale differs from wl_surface.buffer_scale, then the compositor may choose a mode that matches either the buffer size or the surface size. In either case, the surface will fill the output.
This request gives the surface the role of a fullscreen shell surface. If the surface already has another role, it raises a role protocol error.
