ComboBox problems (bug?)

wxPython Users
1

I have this simple example.

Then I try to change the selected value into my combo, on win it "print"
the right value, on linux, it print the preceding value. It's a bug?

And after, on win then this frame is load, there is no values into the
combo, on linux, there is the first load. I think that is better if
there is no values loaded the the frame appear

Thanks,
Michele Petrazzo

import wx

class FramePrev(wx.Frame):
     def __init__(self, parent):
         wx.Frame.__init__(self, parent)
         self.c1 = wx.ComboBox(self, pos=wx.Point(10,10))
         self.c1.Bind(wx.EVT_COMBOBOX, self.oncombo1)
         self.c1.Append('test1')
         self.c1.Append('test2')
         self.c1.Append('test3')

     def oncombo1(self, event):
         print self.c1.GetValue()

class MyApp(wx.App):
     def OnInit(self):
         self.main = FramePrev(None)
         self.main.Show()
         return True

if __name__ == '__main__':
     app = MyApp(0)
     app.MainLoop()

Oopss, "When", not "Then"

Sorry for English,

Which version? I don't see this with the current release, gtk2-unicode build. You could also try to get the new value from the event.GetString() instead.

And after, on win then this frame is load, there is no values into the
combo, on linux, there is the first load. I think that is better if
there is no values loaded the the frame appear

That is just the different ways that the native widgets work. You can make the first value in your list be an empty string and it will work everywhere.

my specific version is:
wx-2.5.3-gtk2-unicode

You could also try to get the new value from the

event.GetString() instead.

I forgot to use this. Thanks

Yes, but after this I see a blank space when I open my combo, and I
don't like this. I'll leave all like now.

Thanks,
