Provides access to a displayable area managed by the compositor. 更多...
import 语句: | import QtWayland.Compositor |
实例化: | QWaylandOutput |
The WaylandOutput manages a rectangular area within bounds of the compositor's geometry, to use it for displaying client content. This could, for instance, be a screen managed by the WaylandCompositor .
The type corresponds to the
wl_output
interface in the Wayland protocol.
注意: If the compositor has multiple Wayland outputs, the Qt::AA_ShareOpenGLContexts attribute must be set before the QGuiApplication object is constructed.
automaticFrameCallback : bool |
This property holds whether the WaylandOutput automatically sends frame callbacks when rendering.
默认为 true。
availableGeometry : rect |
This property holds the geometry of the WaylandOutput available for displaying content. The available geometry is in output coordinates space, starts from 0,0 and it's as big as the output by default.

compositor : WaylandCompositor |
This property holds the compositor displaying content on this WaylandOutput .
注意: This property can be set only once, before the WaylandOutput component is completed.
geometry
:
rect
|
This property holds the geometry of the WaylandOutput .
manufacturer : string |
This property holds a textual description of the manufacturer of this WaylandOutput .
model : string |
This property holds a textual description of the model of this WaylandOutput .
physicalSize : size |
This property holds the physical size of the WaylandOutput in millimeters.
另请参阅 QWaylandOutput::geometry .
position : point |
This property holds the position of this WaylandOutput in the compositor's coordinate system.
scaleFactor : int |
This property holds the factor by which the WaylandCompositor scales surface buffers before they are displayed. It is used on high density output devices where unscaled content would be too small to be practical. The client can in turn set the scale factor of its buffer to match the output if it prefers to provide high resolution content that is suitable for the output device.
The default is 1 (no scaling).
sizeFollowsWindow : bool |
This property controls whether the size of the WaylandOutput matches the size of its window.
If this property is true, all modes previously added are replaced by a mode that matches window size and screen refresh rate.
默认为 false。
subpixel : enum |
This property holds the subpixel arrangement of this WaylandOutput .
默认为 WaylandOutput .SubpixelUnknown.
transform : enum |
This property holds the transformation that the QWaylandCompositor applies to a surface to compensate for the orientation of the QWaylandOutput .
默认为 WaylandOutput .TransformNormal.
window : Window |
This property holds the Window for this WaylandOutput .
注意: This property can be set only once, before the WaylandOutput component is completed.
