Re: problem with custom menu

[John Taber <jtaber johntaber net>]

Huh?  I'm simply trying to build a simple menu and "::attach" with the table 
coordinates is exactly what is in the gtkmm API documentation (under 
widgets/menu) and what compiles (menu->append will not compile for me). I 
don't want to use actions for several reasons related to what other widgets I 
want on a toolbar and besides, simple menus should be just as little coding 
as using all the action statements and xml descriptions.  I got the feeling 
that the ::attach with table coordinates was new in 2.4 but I am not trying 
to debate that - I simply cannot attach/append, whatever, sub items to my 
file menu and there are no examples with attach so I would appreciate any 
help trying to get this to work.  Yes, it should not be difficult, I am not 
trying to do anything strange here.
