[PyQt] QtQuick ApplicationWindow

[Fabien Castan]

Oops... Thanks!

Now, I have 2 strange things:

1) If I put all the code into a function, the application stay stuck when I
try to close it.

https://github.com/buttleofx/testsQml/tree/qmlApplicationWindow
> python3 testQmlApplicationWindow.py
A
B
C
D
E
F
<Here the application is created, I can use it>
<Now I close the application>
Z
<But it stays stuck here... I have to kill it.>

The 'print("End")' is never called.
If I create the QGuiApplication outside of the function, it works fine.
Something like:
"

if __name__ == '__main__':
    app = TestApp(sys.argv)
    main(sys.argv, app)
    app.exec_()
"


2) The second problem is that I can't override the notify function of the
QGuiApplication.
In my sample code there: https://github.com/buttleofx/testsQml/tree/
qmlApplicationWindow, the code is commented...
If I uncomment the notify function:
> python3 testQmlApplicationWindow.py
A
B
C
<It stays stuck here... I have to kill it.>

So it stays stuck on the "component.loadUrl()"

Fabien
