[pygtk] Drawing widgets in a custom cellrenderer

[F Wolff]

Thanks for your reply, Johan. I'll try to clarify my question more
below...

I see. I don't find .draw_rectangle() anywhere, though. The issue is
that I want the widget (a container) to draw itself (and all its
children) normally, but I'm guessing I need to pass the widget it needs
to draw on, etc.

The reason I mention the parent is just that I assume that the
self.widget I create has to be a child of some widget in order to be
realised, and the cellrenderer where I instantiate it is not a
gtk.Widget.  gtk.CellRendererText displays something like a gtk.Label
(when not editing a cell), so I would like to do something like that -
just with any widget of my liking. I've worked out how to plug in my own
widget for the editing mode (with do_start_editing), but I don't see how
to do that for the default mode.

Thanks for any help.
