RE: Anygui on Zaurus

Glad to see a fellow Zaurus user :-) I've a few comments below.

That's a good idea, I didn't think of embedded support and I started to use anygui for pretty much the same reason as you :-)

I'm also new to python, so my suggestion below may not be the "best" python approach.

The above change will break QT backends where QT embedded is NOT installed (e.g. Windows boxes and most Linux QT installations). Consider TRYing to import the embedded stuff thusly:

# ----- code -----
try:
    from qtpe import *
    USE_QPE = 1
except:
    USE_QPE = 0
# ----- code -----

Then instead of blanket changing the QApplication references consider:

# ----- code -----
    if USE_QPE == 1 :
        a = QPEApplication(sys.argv)
    else:
        a = QApplication(sys.argv)
# ----- code -----

I would guess this would give you more chance of getting your changes submitted into the AnyGUI codeline.

I use this approach in a QT application I've written (also using Py-sqlite) where anygui wasn't suitable (I really wanted a table field and whilst I was able to "emulate" it using a text view, it didn't work that well).

I'd be careful with these types of changes as if you have a different backend you run the chance of having different behaviours (e.g. what happens if you use the win32 backend or the TK one?) when you move your application.
