The QWaylandSurface class represents a rectangular area on an output device.
This class encapsulates a rectangular area of pixels that is displayed on an output device. It corresponds to the interface
wl_surface
in the Wayland protocol.
This enum type is used to specify the origin of a QWaylandSurface 's buffer.
| 常量 | 值 | 描述 |
|---|---|---|
QWaylandSurface::OriginTopLeft
|
0
|
The origin is the top left corner of the buffer. |
QWaylandSurface::OriginBottomLeft
|
1
|
The origin is the bottom left corner of the buffer. |
此特性保持 QWaylandSurface 's buffer scale. The buffer scale lets a client supply higher resolution buffer data for use on high resolution outputs.
访问函数：
| int | bufferScale () const |
通知程序信号：
| void | bufferScaleChanged () |
This property holds the client using this QWaylandSurface .
访问函数：
| QWaylandClient * | client () const |
This property holds the orientation of the QWaylandSurface 's contents.
访问函数：
| Qt::ScreenOrientation | contentOrientation () const |
通知程序信号：
| void | contentOrientationChanged () |
另请参阅 QWaylandOutput::transform .
This property holds whether the QWaylandSurface is a cursor surface.
访问函数：
| bool | isCursorSurface () const |
| void | markAsCursorSurface (bool cursorSurface ) |
通知程序信号：
| void | cursorSurfaceChanged () |
This property holds whether the QWaylandSurface has content.
访问函数：
| bool | hasContent () const |
通知程序信号：
| void | hasContentChanged () |
This property holds the origin of the QWaylandSurface 's buffer, or QWaylandSurface::OriginTopLeft if the surface has no buffer.
访问函数：
| Origin | origin () const |
通知程序信号：
| void | originChanged () |
此特性保持 QWaylandSurface 's size in pixels.
访问函数：
| QSize | size () const |
通知程序信号：
| void | sizeChanged () |

若
QWaylandSurface

[signal]
void
QWaylandSurface::
redraw
()
Sends pending frame callbacks.
设置此 QWaylandSurface 's primary view to view , in case there are multiple views of this surface. The primary view is the view that governs the client's refresh rate. It takes care of discarding buffer references when QWaylandView::advance () is called. See the documentation for QWaylandView::advance () 了解更多细节。
In shell surface integrations, such as QWaylandWlShellIntegration and QWaylandXdgShellV5Integration, maximize and fullscreen requests from the client will only have an effect if the integration has the primary view of the surface.

updateSelection
()
Updates the surface with the compositor's retained clipboard selection. Although this is done automatically when the surface receives keyboard focus, this function is useful for updating clients which do not have keyboard focus.
Returns the views for this QWaylandSurface .
