The QWaylandOutput class represents a displayable area managed by the compositor.
The QWaylandOutput 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 class corresponds to the
wl_output
interface in the Wayland protocol.
This enum type is used to specify the subpixel arrangement of a QWaylandOutput .

This property holds the factor by which the QWaylandCompositor scales surface buffers before they are displayed. This 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).

This property controls whether the size of the QWaylandOutput 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.

Default constructs an instance of QWaylandOutput.
構造 QWaylandOutput in compositor and with the specified window 。 create() function must be called on the compositor before constructing a QWaylandOutput for it.
The QWaylandOutput object is initialized later, in reaction to an event. At this point it is added as an output for the compositor . If it is the first QWaylandOutput object created for this compositor , it becomes the default output .
銷毀 QWaylandOutput .
Adds the mode
mode
to the output and mark it as preferred if
preferred

true
. Please note there can only be one preferred mode.
Returns the compositor for this QWaylandOutput .
注意： getter 函數對於特性 compositor .
Returns the output's size in pixels and refresh rate in mHz. If the current mode is not set it will return an invalid mode.
