Represents a rectangular area on an output device. More...
Import Statement: | import QtWayland.Compositor |
Since: | Qt 5.8 |
Instantiates: | QWaylandSurface |
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.
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.
bufferSize : size
This property holds the size of the current buffer of this WaylandSurface in pixels, not in surface coordinates.
For the size in surface coordinates, use destinationSize instead.
See also destinationSize and bufferScale.
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.
[since 5.13] destinationSize : size
This property holds the size of this WaylandSurface in surface coordinates.
This property was introduced in Qt 5.13.
See also bufferScale and bufferSize.
hasContent : bool
This property holds whether the WaylandSurface has content.
[since 5.14] inhibitsIdle : bool
This property holds whether this surface is intended to inhibit the idle behavior of the compositor such as screen blanking, locking and screen saving.
This property was introduced in Qt 5.14.
See also IdleInhibitManagerV1.
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:
[since 5.13] sourceGeometry : rect
This property describes the portion of the attached Wayland buffer that should be drawn on the screen. The coordinates are from the corner of the buffer and are scaled by bufferScale.
This property was introduced in Qt 5.13.
See also bufferScale, bufferSize, and destinationSize.
useTextureAlpha : bool
This property specifies whether the surface should use texture alpha.
childAdded(WaylandSurface child)
This signal is emitted when a wl_subsurface, child, has been added to the surface.
Note: The corresponding handler is onChildAdded
.
void dragStarted(WaylandDrag drag)
This signal is emitted when a drag has started from this surface.
Note: The corresponding handler is onDragStarted
.
surfaceDestroyed()
This signal is emitted when the corresponding wl_surface is destroyed.
Note: The corresponding handler is onSurfaceDestroyed
.
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
