Subject: wx.Notebook and button events

Hello,

I happened upon a rather strange behaviour while programming
wxPython using SPE on Linux, using wxPython 2.8.4.0 and Python 2.5.

The example code below creates a simple frame containing a
wx.Notebook with two tabs. Each tab has a button, both with
the same label.

Now, when I klick either one of those buttons, events for
both of them are generated - first the one on the second tab,
then the one on the first.

Is this expexted behaviour? Am I doing something wrong?

Thank you for your answers,

Johannes

if __name__ == "__main__":
     app = wx.PySimpleApp(0)
     wx.InitAllImageHandlers()
     frame_1 = MyFrame(None, -1, "")
     app.SetTopWindow(frame_1)
     frame_1.Show()
     app.MainLoop()

The issue is that you gave both buttons the same id. Use wx.ID_ANY
instead.
