Yep.  This is my goal really.  I was thinking of a list in each widget
section of all the important signals you can use with it, including ones
not in the example..

Yeah.. oh well :)  So long as the info is there somewhere really.. I spose
the idea of confusing beginners is a definite possibility.

I was wondering why I couldn't see how the menuitem emits the "clicked"
signal.. is it inhereted somehow ?

Hmm.. perhaps for now.. I think the best thing really would be a list of
all signals emitted by a given widget in that widgets section.
