Dear urwid users,
I am starting to take a look at urwid after a quite long brake again...
so I am still a newbie :-)
I am a bit confused about the handling of button-press reactions and
setting focus using keys for different widgets. I attached a small
example. The aim is to show a help text or some more buttons on the
right green 'box' in the inner-frame as soon as I walk through the
buttons. The focused is set to the buttons, but as soon as I press one
of the buttons I would like to focus to the current content of the right
green column.
It would be nice, if anyone has a hint, how to achieve this!?
Thanks!
Fabian
