As I said, I want to add some kind of tooltip to any menu a user
selects. My users don't read manuals and they don't know to look at
the status bar (which is where normally this kind of help is
dsplayed).
So I thought it would be a cool idea to provide this kind of help -
sort of pushing some information onto the user (ok, they'll get the
option of turning it off).

Yes I know, I just thought it would be worth a try.

Well, maybe the situation is not as hopeless then.
Some background info: The app is written in Tcl/Tk and _Tk_ is
handling the menus itself (playing around with GetMenuItemInfo I found
the style 'owner drawn'). I can attach a (Tcl) callback function which
gets activated whenever a menu is posted, and there I can even
retrieve the active item's index - all on the Tcl level. I just cannot
get the coordinates.
Now, if you cannot do something from the Tcl level, you always have
the option of implementing the missing functionality in C (on the Tcl
side this is called an extension) and then call it like any other
command.

So, in my (Tcl) callback function I have access to a - in Tcl speak -
a widget: something I can obtain a hWnd of. I just don't get the
needed positional information from there.

Well, needs some more experiments :(
Thanks and best regards
