Re: multiple widget inheritance

Currently the GtkObject system does not handle multiple inheritence very
well.  There have been a number of hacks, such as the activate interface
and the set_scroll_adjustments interface though.

You may be able to do this by creating a few signals for each widget, and
making a few functions that simply call gtk_signal_emit_by_name to make up
the common interface.
