You don't need to call QApplication::exec to have an event loop. A local event loop is created automatically whenever you call QMenu::exec, QDialog::exec or one of the static QMessageBox methods. You still need a QApplication of course. Try this to see from PyQt4 import QtGui import sys app = QtGui.QApplication(sys.argv) QMessageBox.critical(None,"Hello","World") control returns to the caller after the message box is closed.
