I think your problem is this:
self.statusBar = self.CreateStatusBar()
self.SetStatusBar(self.statusBar)
Unless you want to create a custom status bar, you should
just
do:
self.CreateStatusBar()
I think doing it the way you did creates two status bars 2nd
to the
panel.
Also you don't need this class:
class SetStatusBarText(wx.StatusBar):
You aren't creating a custom status bar so even if you
wanted to use it it
shouldn't inherit from wx.StatusBar.
just do parent.SetStatusText(text) where you want to change
statusbar contents (or self.SetStatusText(text) if you are
in
the frame object).
This creates your second statusBar on the panel:
self.statusBar = SetStatusBarText(self.frame, "Radio
button 2 is activated")
Change it to the following (not tested but pretty sure):
parent.SetStatusText("Radio button 2 is
activated", 0)
