This is a manual test of QWindow::requestActivate() and how it interacts with implicit activation from the window system. Written in order to test QtWayland, but hopefully also useful for testing on other platforms. Task-number: QTBUG-91542 Change-Id: Id18dc6d146d213a7c730cff343d9fc25f6c42514 Reviewed-by: Eskil Abrahamsen Blomfeldt <eskil.abrahamsen-blomfeldt@qt.io>
