WaylandSurface QML Type▲
-
Import Statement: import QtWayland.Compositor 1.3
-
Since: Qt 5.8
Detailed Description▲
This type encapsulates a rectangular area of pixels that is displayed on an output device. It corresponds to the interface wl_surface in the Wayland protocol.
Property Documentation▲
bufferScale : size▲
This property holds the WaylandSurface's buffer scale. The buffer scale lets a client supply higher resolution buffer data for use on high resolution outputs.
client : WaylandClient▲
This property holds the client using this WaylandSurface.
contentOrientation : enum▲
This property holds the orientation of the WaylandSurface's contents.

See also WaylandOutput.transform
cursorSurface : bool▲
This property holds whether the WaylandSurface is a cursor surface.
hasContent : bool▲
This property holds whether the WaylandSurface has content.
origin : enum▲
This property holds the origin of the WaylandSurface's buffer, or WaylandSurface.OriginTopLeft if the surface has no buffer.
It can have the following values:
-
WaylandSurface.OriginTopLeft The origin is the top left corner of the buffer.
-
WaylandSurface.OriginBottomLeft The origin is the bottom left corner of the buffer.
size : size▲
This property holds the WaylandSurface's size in pixels.
useTextureAlpha : bool▲
This property specifies whether the surface should use texture alpha.
Signal Documentation▲
childAdded(WaylandSurface child)▲
This signal is emitted when a wl_subsurface, child, has been added to the surface.
The corresponding handler is onChildAdded.
void dragStarted(WaylandDrag drag)▲
This signal is emitted when a drag has started from this surface.
The corresponding handler is onDragStarted.
surfaceDestroyed()▲
This signal is emitted when the corresponding wl_surface is destroyed.
The corresponding handler is onSurfaceDestroyed.
Method Documentation▲
void destroy()▲
Destroys the WaylandSurface.
void initialize(WaylandCompositor compositor, WaylandClient client, int id, int version)▲
Initializes the WaylandSurface with the given compositor and client, and with the given id and version.
bool isDestroyed()▲
Returns true if the WaylandSurface has been destroyed. Otherwise returns false.
Obsolete Members for WaylandSurface▲
The following members of QML type WaylandSurface are deprecated. We strongly advise against using them in new code.
Obsolete Property Documentation▲
clientRenderingEnabled : bool▲
This property is deprecated. We strongly advise against using it in new code.
This property used to specify whether client rendering was enabled for the surface. It depended on a Wayland extension that was part of the private API. The surface extension is not used anymore, so this property does nothing.
