<br>
<br>
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). <br>
<br>
The code seems correct but it terminates with a segmentation fault when
the QUIT button is pressed : <br>

I don't understand what happens. <br>
Is there any explanation ? <br>

Thanks a lot, <br>

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