 Yeah, allowing to set a child widget would be much nicer to the
programmer. It would also be more powerful; you could easily build a
combo box by setting a GtkButton on it. :) (Nobody is going to do a
regular combo box, but e.g. a browser may want to do a specialized combo
box where you select a search engine.)

 The set_icon() is maybe too specialized. It would require a special
signal for when clicked, and programmers would want to set the hand
mouse cursor on it to indicate it is clickable. Exposing its GdkWindow
could be avoid having methods for these, but...

 Let's settle on the child widget solution? Always better to go for the
superset I think. :)

Cheers,
 Ricardo
