Sure, that works fine for plaintext.  But setting up cut & paste of
other types is much more complicated, since you have to mess with the
GtkTargets and GtkAtoms which are entirely non-trivial to use.

I didn't know about these ones.  But it is still a fair amount of work
to implement cut & paste menus for a window, because you have to hook up
the menu item signals, check which widget has the focus, make sure that
the cut/copy/paste items are appropriately made (in)sensitive (possibly
checking the types in the clipboard), handle type conversions, etc.  So,
a 100% correct implementation is very complicated.

Maybe there should be some kind of clipboard manager object that follows
keyboard focus, updates the menu/toolbar items properly and routes the
cut & paste requests to the right widgets automatically.  I haven't put
much thought into it but it's something that could make apps much easier
to code.

BTW, likewise, some kind of Undo API would be nice too.
