Unable to get wxPython Sizers to work correctly
I am a newbie to Python although I have many years' experience in other languages. The main issues I am having is with Sizers. Using only BoxSizers I have managed to get things working as expected. However when I incorporated a GridBagSizer I found that I could only stretch the Window horizontally and not vertically. I have searched through previous queries but not found anything that exactly matches my problem.
I have been bogged down for over a day so thanks in advance for any responses...
The code for the App and Frame is:-
#!/usr/bin/env python
#Boa:App:BoaApp`enter code here`
import wx
import Frame9
modules ={'Frame9': [1, 'Main frame of Application', 'none://Frame9.py']}
class BoaApp(wx.App):
def OnInit(self):
self.main = Frame9.create(None)
self.main.Show()
self.SetTopWindow(self.main)
return True
def main():
application = BoaApp(0)
application.MainLoop()
if __name__ == '__main__':
main()
#Boa:Frame:Frame9

Change this:
self.boxSizer1.Add(self.gridBagSizer1, 0, wx.ALL|wx.EXPAND)
to:
self.boxSizer1.Add(self.gridBagSizer1, 1, wx.ALL|wx.EXPAND)
Following is an alternative way of doing your layout with wxPython using sized_controls. I really like them as I now adays find it easier to layout screens with them instead of using a UI designer like Boa (which I liked a lot and have used in the past).
A few notes to the code, I used wxversion as I have a few wxPython versions installed on my machine, so needed to select one.
To find out more about: sized controls - http://wiki.wxpython.org/SizedControls WIT - http://wiki.wxpython.org/Widget%20Inspection%20Tool

paneControls.SetSizerProps(expand=True, proportion=1)
