How does an object register itself in this registry?

I'm pretty pragmatic about these things. There has to be a way for the
app to get a pointer to a function that knows about menus. Whichever
way you get it the object must know about menus, so i feel the already
existing way is more natural. This is quite like the way the
properties dialog works now (with get_properties and apply_properties).

All hardware? Isn't that a little hard. Kinda hard doing software
without any. Programming turing machines isn't all that fun.

Ok, i think i agree with you. Middle button is the object specific
menu.Right button the general. I don't know if there should be any
default items in the object menu though. If there were, say
move-to-front, should it work on that object only, or (as the one int
the right menu) on all selected objects.

I feel that keyboard shortcuts in the object menu, which changes with
time and mouse-position, would be confusing. Better to not have any.
Dia isn't really usable without mouse anyway.

Agreed, non-changing right button menu.
