Re: Tab pressing

["R. Douglas Barbieri" <dooglio gmail com>]

Wouldn't it work to listen to the keypress event in the container
widget of the controls he wants to tab through? Or do the child
widgets grab up the events before you get them?

If that's the case, the child widgets would still have to listen to
their own key_press events, but then pass on tabs to the containing
widget.
