We need to let the QGuiApplication determine whether quitting is appropriate based on whether there are visible top level QWindows after the last top-level QWidget was closed. This solves the issue raised here: http://thread.gmane.org/gmane.comp.lib.qt.user/1880 The transientParent is the QWindow equivalent of parentWidget on QWidget, so the test in QGuiApplication::shouldQuit is similar to the one in QApplication::shouldQuit.
