I think this makes a ton of sense. In all the cases I had considered, =20=

there was no way the widget would be able to display something =20
reasonable with the invalid data. Your example of a graph-like widget =20=

made a lot of sense, as well as the notion of extracting as much =20
worthwhile information as possible and putting it up for display. So, =20=

in light of that, I'd propose add a view concept API to something like:

	void singleton(const model_type& value);

We might also want to have a nullary singleton function for the case =20
when the widget is asked to display something it can't decipher. For =20
example, an edit text field being asked to display an icon:

	void singleton();

Thoughts?

Blessings,
Foster
