multiple widget inheritance

[Rodrigo Moya <rmoya tsai es>]

Hi all!

I am making a library of data-bound widgets, and right now each widget
is a subclass of a different GTK/GNOME widget class (GtkVBox,
GnomeDialog, GtkEntry...). But I would like to have a base class for all
of these widgets for common properties and signals. Is there any way of
having all widget classes subclassing this base class, and then each of
them subclassing another GTK/GNOME class without losing the
object-oriented design? I guess there isn't, but I ask just in case
somebody has found a good way of doing it.

Cheers
