Ok, now I've got a serious problem. Whats wrong with the following code?
When executing it i always get the following message:
Help? 
Code:
import sys
from PyQt4 import QtCore, QtGui
class SlmListView( QtGui.QWidget ):
def __init( self, parent = None, core = None ):
QtGui.QWidget.__init__( self, parent )
self.myLayout = QtGui.QVBoxLayout()
self.setLayout( self.myLayout )
def populate( self ):
for i in [1, 2, 3]:
self.myLayout.addWidget( QtGui.QPushButton( str( i ) ) )
class SlmMainView( QtGui.QMainWindow ):
def __init__( self, parent = None ):
QtGui.QWidget.__init__( self, parent )
self.slmListView = SlmListView()
self.slmListView.populate()
self.setCentralWidget( self.slmListView )
if __name__ == "__main__":
app = QtGui.QApplication( sys.argv )
slmMainView = SlmMainView()
slmMainView.show()
sys.exit( app.exec_() )
When executing it i always get the following message:
Code:
C:\develop\Python>python app.py
Traceback (most recent call last):
File "app.py", line 26, in <module>
slmMainView = SlmMainView()
File "app.py", line 20, in __init__
self.slmListView.populate()
File "app.py", line 12, in populate
self.myLayout.addWidget( QtGui.QPushButton( str( i ) ) )
AttributeError: myLayout

Let me do a quick check. I should be able to figure out your problem when I get back to my main computer.

In line five you have the following:
You forgot the two trailing underscores after "init". It should be:
When you add them, the program displays a window with three buttons stacked vertically.
The error message was "AttributeError". It says that it could not find the attribute "myLayout" in the SlmListView. What happened was that the __init creator never got called, because it has the wrong name. So the myLayout never got created. So it could not be found.
How did I find the error? I figured there was something wrong with the myLayout. So I put in lines "print myLayout" when it was created and before it was used in populate(). The print in the constructor never happened. That's when I realize the constructor was never being called. And that led me to discover that it was mis-named.

Wow, thanks, you're a genius! I had nearly given up on it. Forgetting stuff like underscores, dots, commas etc) is typical for me *g* Thank you!

I'm currently developping a panohead driving application in PyGTK, and start to have serious troubles (I got some seg. fault on some OS, not on others...). That's a long time I plan to switch to PyQt, as I also use it in my every-day job.
The question is: is it planned to have a PyQt version for OS2007? Some users of my app. are running it on 770s, and I don't want them to be excluded from futur devs...

I downloaded an old favourite of mine, Treeline...
It ran without problems

I try PyQt for Diablo and get segmentation fault
Should PyQt works in scratchbox?

PyQt most certainly works on Diablo. Can you post some code that demostrates the crash ? Most of the time segfaults happen when objects get destructed 'behind' PyQt's back and then you try to reference them.

@Nyrath:
The flickr-pics only show the application in windowed mode. Do you know if there's support for the hardware keys and fullscreen integrated?
