SetMaxLength for ComboBox

wxPython Users

Thank you Robin, that works well:

     def OnTextValue(self, evt):
         """User has inserted text into combo box;
         check that maximum length is not exceeded
         """
         wnd = evt.GetEventObject()
         s = wnd.GetValue()
         over = len(s) - self.valueLength
         if over > 0:
             n = wnd.GetInsertionPoint()
             m = n - over
             wnd.SetValue(s[:m] + s[n:])
             wnd.SetInsertionPoint(m)

Hi all,
I want to limit the number of characters typed into the text field of a CB_DROPDOWN ComboBox. I thought I had seen a way of getting the TextCtrl so I can apply SetMaxLength(), but can't find any references to it in the archives.

Unfortunately there isn't a built-in way to do tha with a combobox. You'll have to catch events (EVT_CHAR and/or maybe EVT_TEXT) and impose the limit yourself.
