Cross-platform issue with wxRadioBox

[gokhvat@gmail.com]

I am experiencing a strange cross-platform issue with my python
program.

I am using wxRadioBox to create radio buttons. When I run the python
code on a mac, everything works perfectly, but not on a pc. On the pc,
no matter what selection I made, the form would think that I was
choosing the 1st (top) option.

I am astounded that everything else could work and something this
simple could have cross-platform issues.

I looked into wxRadioBox online and no one seems to have any similar
errors. I was thinking it might be the installation of the wx module on
the pc, but I somehow doubt it.

Does anyone have any insight as to what is going on here?

Re: Cross-platform issue with wxRadioBox

I have updated my script to use wx.RadioButton instead, which works
perfectly on my mac again, but now the submit button doesn't show up on
the pc and I can't click in the netid field on the pc either. any
ideas?

I modified the __init__() method of class regFrame from your original
posting to create a wx.Panel as a child of self and then made all the
controls be children of this panel. Your app then seemed to work OK on
Windows XP. Using a wx.Panel to hold the content of a frame is a
standard wxPython idiom. I find reading the wxPython demo source is a
very useful way to learn this sort of thing.
