◆ initialize()

void QWaylandTextureSharingExtension::initialize ( )

overridevirtual

Initializes the QWaylandCompositorExtension.

The default implementation adopts the parent object as extension container if none has been set, and if the parent inherits from QWaylandObject. The default implementation also adds the QWaylandCompositorExtension to the list of extensions managed by the extension container.

Override this function in subclasses to provide custom initialization code.

Reimplemented from QWaylandCompositorExtension.
