Detailed Description

\inmodule QtWaylandCompositor

Since
5.8

QWaylandObject is the base class for objects that can contain Wayland extensions.

The QWaylandObject encapsulate extension container functionality. Any QWaylandObject object will automatically be an extension container and QWaylandCompositorExtension object which is a child of this will automatically add itself to its extension list, and remove itself when the extension object is destroyed.
