QtGamepad blocks potential plans for a Qt 6 port
Kirogi is the only KDE application that uses QtGamepad in KDE.
The Qt Company says that they are not interested in a release of the module as is.
They have [vague] plans to bring the functionality back as part of a module that would also support VR controllers.
The code for qtgamepad is available on git and should be in a compilable state or very close to make it compile. Patches are welcome.
One suggestion from The Qt Company representatives would be to just copy the files over tp if Kirogi it is ported to Qt6 before the new Qt module is released.
