What is WaylandView?

114 views Asked by At

I read https://doc.qt.io/qt-5/qml-qtwayland-compositor-waylandview.html#details but still cannot understand what is WaylandView. I tried to see how WaylandView works, but which type cannot be found.

WaylandView is not a type

I also tried WaylandQuickItem which looks like the wrapper class of WaylandView. but cannot understand the difference, why make WaylandView registered in QML but cannot create the instance? What it is used for?

WaylandView is mostly used if you are implementing a compositor in C++. In QML it's mostly an implementation detail, and WaylandQuickItem and ShellSurfaceItem wraps and uses it internally.

If you need to do something really specific that's incompatible with ShellSurfaceItem and WaylandQuickItem it could probably be useful, but otherwise it's safe to ignore it.

The QML cocumentation could probably have been better for that type ;)
