PyQt: Can't show PY variable in QT filedialog as initially parameter

Hi,

I use PyQt 3.8 non-commercial version in win32. I get a big question.
I Can't show PY variable in QT filedialog as initially parameter.

Code sample is following:
~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~ ~~~~~~~~~
fileName="test. avi"

def saveSomething(a String):
dl = QFileDialog.get SaveFileName(aS tring, "*.*", self, "FileDialog ")
or
dl = QFileDialog.get SaveFileName(QS tring(aString), "*.*",
self, "FileDialog ")
~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~ ~~~~~~~~~~~~~~~ ~~~~~~~~
these code can't show corrent string.

If I use string constant.
dl = QFileDialog.get SaveFileName("t est.avi", "*.*", self, "FileDialog ")

Dialog show it correctly.

Thanks.

Maybe try:

dl = QFileDialog.get SaveFileName(st r(aString), "*.*", self, "FileDialog ")

Above code is a example. I do a little application for free.
main form will arrive 1XXX line. So I can't post it all.

BTW: I can't show getExistingDire ctory Dialog in a python thread.
it's will halt whole program.

Hello, I wanted to take a look at the qtext module which has been advertised on the PyQT overview page, but am unable to get it. How am I supposed to do this? I installed Python v2.3 from www.python.org (using the self-installing executable), QT non-commercial edition 2.3.0 and then PyQT non-commercial edition 3.8.0 using the self-installing executable PyQT-win-nc-3.8.exe from riverbankcomputing.co.uk.

Still trying to learn PyQt from a book about several Python GUI toolkits, I seem to learn first what doesn't work.

I will now die. I am too ignorant to make it work. 10.2.setEventCB.py segfaults for me. It is almost there, but it is not there. SoQt.init returns a string, which I can't use as the parent widget of my PyQt derived class. SoQt.show and mainLoop need a string as a parameter, so my PyQt derived class can't go there.
