OK, seems like my issue is only when style includes wx.CB_READONLY.

This code only prints 0, not 1:

import wx

class MyFrame(wx.Frame):
    def __init__(self):
        wx.Frame.__init__(self, None, title='combo')
        panel = wx.Panel(self)

        choices = ['cat', 'dog', 'pig']
        cb0 = wx.ComboBox(panel, choices=choices)
        cb1 = wx.ComboBox(panel, choices=choices, style=wx.CB_READONLY)
        cb0.Bind(wx.EVT_TEXT, self.onTextChange0)
        cb1.Bind(wx.EVT_TEXT, self.onTextChange1)
        cb0.SetValue('dog')
        cb1.SetValue('dog')
        self.Show()

    def onTextChange0(self, event):
        print '0'

    def onTextChange1(self, event):
        print '1'

if __name__ == '__main__':
    app = wx.App(False)
    frame = MyFrame()
    app.MainLoop()
