\qmlproperty object QtWayland.Compositor::WaylandQuickItem::subsurfaceHandler
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.
The default value of this property is null

This signal is emitted when the client has destroyed the wl_surface

If an animation is started, bufferLocked should be set to ensure the item keeps its content until the animation finishes

Called on the render thread when it is time to sync the state of the item with the scene graph.
The function is called as a result of QQuickItem::update(), if the user has set the QQuickItem::ItemHasContents flag on the item.
The function should return the root of the scene graph subtree for this item. Most implementations will return a single QSGGeometryNode containing the visual representation of this item. oldNode is the node that was returned the last time the function was called. updatePaintNodeData provides a pointer to the QSGTransformNode associated with this QQuickItem.
The main thread is blocked while this function is executed so it is safe to read values from the QQuickItem instance and other objects in the main thread.
If no call to QQuickItem::updatePaintNode() result in actual scene graph changes, like QSGNode::markDirty() or adding and removing nodes, then the underlying implementation may decide to not render the scene again as the visual outcome is identical.

By default, the item locks the current buffer until a new buffer is available and updatePaintNode() is called.
Set this property to true to allow Qt to release the buffer immediately when the throttling view is no longer using it. This is useful for items that have slow update intervals.
