It looks pretty good, but I wonder if there is a way to do it in a more
Instead of isinstance() perhaps we could check for a size_hint attribute
and use it if it's there. That way people that know they are only using
"my_widget" in one container could just do something like:
my_widget.size_hint = 'weight'
my_widget.size_hint_weight = 5
I would prefer to name the classes FlowHint, WeightHint and FixedHint
and make them part of the urwid namespace (not a separate submodule), so
the same thing as above without modifying my_widget would be:
my_hinted_widget = urwid.WeightHint(my_widget, 5)
The hint classes could inherit from a new base class I'm planning to add
"DecoratorWidget". See: http://excess.org/urwid/wiki/NewBaseClasses
