问题描述:

I'm learning wx.Python and i write a small example in Windows XP and run perfect, but the same code in ubuntu Jaunty don't work well.

The fonts of wx.Choice appear desfased and the options are barely visible, when you chosee one, the Label is always empty.

self.button1.Label='MULT'

event.Skip()

if __name__ == '__main__':

app = wx.PySimpleApp()

frame = create(None)

frame.Show()

app.MainLoop()

The print self.choice1.Label always print EMPTY in ubuntu, and in Windows print suma, resta or mul, one of the options of the wx.choice, how expected.

It's an error to use self.choice1.Label; replace it throughout your code with self.choice1.StringSelection and your code works!
