The wxPython 2.5.2.x MigrationGuide.html document has an example using=20=

wx.NavigationKeyEvent, which is new with wxPython 2.5.2. Adapting that=20=

to cause the return key to behave the same as the tab key using=20
PythonCard event attribute names gives us this example:

     def on_keyDown(self, event):
         # wx.WXK_RETURN is 13
         if event.keyCode =3D=3D wx.WXK_RETURN:
             if event.shiftDown:
                 flags =3D wx.NavigationKeyEvent.IsBackward
             else:
                 flags =3D wx.NavigationKeyEvent.IsForward
             if event.controlDown:
                 flags |=3D wx.NavigationKeyEvent.WinChange
             event.target.Navigate(flags)
         else:
             event.skip()

Remember that if you use an on_keyDown event handler, all components=20
that receive key events that don't have their own keyDown handlers will=20=

end up using that event handler. If you just want it to handle=20
TextField components you might want to add a test for the class or=20
class name and call event.skip() if necessary. Here's one possibility:

     if event.target.__class__.__name__ =3D=3D 'TextField':
     ...
