QWaylandCompositorExtensionTemplate is a template class which inherits QWaylandCompositorExtension and is convenience for building custom Wayland extensions with Qt.
It provides the connection between Qt Wayland Compositor and the class generated by
qtwaylandscanner, based on the XML description of the extension protocol.
It provides two specific pieces of convenience:
- A reimplementation of QWaylandCompositorExtension::extensionInterface() which returns the
wl_interfacepointer for the qtwaylandscanner-generated base class.
- A static findIn() function which searches for an instance of the extension in a provided container, and returns this if it is found.
Typically, a new extension will dual-inherit QWaylandCompositorExtensionTemplate and the class generated by
QWaylandCompositorExtensionTemplate should be parameterized with the subclass itself:
class MyExtension : public QWaylandCompositorExtensionTemplate<MyExtension> , QtWaylandServer::my_extension
In this example,
MyExtension is an implementation of the generated interface

Member Function Documentation
[static] T *QWaylandCompositorExtensionTemplate::findIn(QWaylandObject *container)
If any instance of the interface has been registered with container, this is returned. Otherwise null is returned. The look-up is based on the generated
interfaceName() which matches the interface name in the protocol description.
