	I have a requirement to capture the RETURN key and treat it like
a TAB so that both TAB and RETURN will perform the same function.   I
have a "global" on_keyPress(self, event) defined but need help in
figuring out the syntax of the event to fire:=20

	=20

	def on_keypress(self, event):=20

	=20

	           if event.keyCode =3D=3D wx.WXK_RETURN:=20

	=20

	                event.target.MouseUpEvent=20

	=20

	                # other things I've tried that don't work=20

	=20

	                #self.components.keys(wx.WXK_TAB)=20

	=20

	                #event.m_keyCode =3D wx.WXK_TAB=20

The wxPython 2.5.2.x MigrationGuide.html document has an example using
wx.NavigationKeyEvent, which is new with wxPython 2.5.2. Adapting that
to cause the return key to behave the same as the tab key using
PythonCard event attribute names gives us this example:=20

=20

def on_keyDown(self, event):=20

# wx.WXK_RETURN is 13=20

if event.keyCode =3D=3D wx.WXK_RETURN:=20

if event.shiftDown:=20

flags =3D wx.NavigationKeyEvent.IsBackward=20

else:=20

flags =3D wx.NavigationKeyEvent.IsForward=20

if event.controlDown:=20

flags |=3D wx.NavigationKeyEvent.WinChange=20

event.target.Navigate(flags)=20

else:=20

event.skip()=20

Remember that if you use an on_keyDown event handler, all components
that receive key events that don't have their own keyDown handlers will
end up using that event handler. If you just want it to handle TextField
components you might want to add a test for the class or class name and
call event.skip() if necessary. Here's one possibility:=20

=20

if event.target.__class__.__name__ =3D=3D 'TextField':=20
