[urwid] executing a callback when a widget gets focus

[Robert Urban]

Hello,

in the past I have successfully been using the following construct to have a

self._parent = parent
return self.__super.__init__(walker)
return self.__super._get_focus_position()
self.__super._set_focus_position(item)
self._parent.update_footer()
focus_position = property(_get_focus_position, _set_focus_position,'')

However this stopped working recently, I guess because the internal
implementation changed. I'm using v1.3.0.

How can I get this to work again?

P.S., the entire test program can be found here:

Hello again,

it seems using

urwid.connect_signal(list_walker, "modified", callback)

is the solution.
