I think the problem here is that Text widets are not selectable, so they 
won't become the focus.  You might try something like this:

class ModuleWidget(urwid.WidgetWrap):
     def __init__(self, mod):
         w = urwid.Text(mod)
         w = urwid.AttrWrap(w, 'module', 'focustext')
         urwid.WidgetWrap.__init__(self, w)
     def selectable(self):
         return True

and in your listbox use:
ModuleWidget( mod )

This is a custom widget that is selectable and will appear the way you 
intended.  You can also add a "keypress" method to this class to handle 
input on your widget.
