实例化: | QWaylandQuickItem |
继承者: | ShellSurfaceItem |
Qt Quick-based Wayland compositors can use this type to display a client's contents on an output device. It passes user input to the client.
bufferLocked : bool |
This property holds whether the item's buffer is currently locked. As long as the buffer is locked, it will not be released and returned to the client.
默认为 false。
compositor : WaylandCompositor |
This property holds the compositor for the surface rendered by this WaylandQuickItem .
focusOnClick : bool |
This property specifies whether the WaylandQuickItem should take focus when it is clicked or touched.
默认为
true
.
origin : enum |
This property holds the origin of the QWaylandQuickItem .
paintEnabled : bool |
Returns true if the item is hidden, though the texture is still updated. As opposed to hiding the item by setting
visible
to
false
, setting this property to
false
will not prevent mouse or keyboard input from reaching item.
subsurfaceHandler : object |
This property provides a way to override the default subsurface behavior.
By default, Qt will create a new SurfaceItem as a child of this item, and maintain the correct position.
To override the default, assign a handler object to this property. The handler should implement a handleSubsurfaceAdded( WaylandSurface ) function.
ShellSurfaceItem { subsurfaceHandler: QtObject { function handleSubsurfaceAdded(child) { //create custom surface item, and connect the subsurfacePositionChanged signal } }
此特性的默认值为
null
.
surface : WaylandSurface |
This property holds the surface rendered by this WaylandQuickItem .
touchEventsEnabled : bool |
This property holds
true
if touch events are forwarded to the client surface,
false
否则。
void surfaceDestroyed () |
This signal is emitted when the client has destroyed the
wl_surface
associated with the
WaylandQuickItem
. The handler for this signal is expected to either destroy the
WaylandQuickItem
immediately or start a close animation and then destroy the Item.
If an animation is started, bufferLocked should be set to ensure the item keeps its content until the animation finishes

point
mapFromSurface
(
point
point

|
Maps the given point in the Wayland surfaces's coordinate system to the equivalent point within this item's coordinate system, and returns the mapped coordinate.
This method was introduced in Qt 5.13.
point mapToSurface ( point point ) |
Maps the given point in this item's coordinate system to the equivalent point within the Wayland surface's coordinate system, and returns the mapped coordinate.
setPrimary () |
Makes this WaylandQuickItem the primary view for the surface.
