After some trickery, this works, sort of:
http://pastebin.com/m4acd9d33
It's inelegant though.
What I'm doing is having the widget paint itself, but putting it in a stack
that handles all events. This makes widgets sort of pointless, but it does
work.
Notable points: the explicit width and height args on the stack are
required. If you don't put them in there, then the widget still draws but
none of the events get passed through.
Also, setting left and top on the stack doesn't change the mouse coords of
the click.
Anyway, I think I'll avoid using widgets for the time being, and just do
everything some other way.
