Hello,
I am a PyQt newbye and I wanted to do some tests with QToolBar in a
QDialog (Seems multiple QMainWindow use is not recommanded in a
QApplication), so I started coding a simple example (reported below).
The code seems correct but it terminates with a segmentation fault when
the QUIT button is pressed :

I don't understand what happens.
Is there any explanation ?
Thanks a lot,

Salut,
Change these lines:
bye_action = QAction("Bye bye", dialog)
bye_action.triggered.connect(say_bye)
toolbar.addAction(bye_action)
quit_action = QAction("Quit", dialog)
quit_action.triggered.connect(quit)
toolbar.addAction(quit_action)
and this one:
sys.exit(app.exec_())
Cheers
