No, QTimer should work in the main thread as well, at least if you started the QApplication via QApplication._exec() Andreas -- You may worry about your hair-do today, but tomorrow much peanut butter will be sold. _______________________________________________ PyQt mailing list [email protected] http://www.riverbankcomputing.com/mailman/listinfo/pyqt
