Detailed Description

A simple wrapper to retrieve the major Wayland objects from the Qt Wayland native interface.

Note

This class requires access to private Qt headers. When processing the libmythui.pro file, qmake will throw out warnings on binary compatibility

our use of the private headers is however limited here, the API has not changed for some time and appears to be stable into Qt6.

Constructor & Destructor Documentation

◆ MythWaylandDevice()

MythWaylandDevice::MythWaylandDevice ( QWidget * Widget )

explicit

Member Function Documentation

◆ IsAvailable()

bool MythWaylandDevice::IsAvailable ( )

static

Check whether we can connect to a Wayland server.

Definition at line 100 of file mythwaylandextras.cpp.

◆ SetOpaqueRegion()

bool MythWaylandDevice::SetOpaqueRegion ( QRect Region ) const

Provide a rendering optimisation hint to the compositor.

This is only a hint and support varies by compositor. As a result we still need to use other workarounds to ensure alpha blending works correctly.
