Re: Creating toolbar menubuttons via UI Manager

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

It's possible to use Gtk::MenuToolButton with Gtk::UIManager in gtkmm, 
but it's rather messy there, too. It's somewhat easier than in gtk+, 
because it's easier to derive new classes in C++ than it is in C.

See the attached file, where I've changed the book/menus/main_menu 
example in the Gtkmm tutorial
(http://developer.gnome.org/gtkmm-tutorial/stable/sec-menus-examples.html.en).
I've derived the class MenuToolAction from Gtk::Action. Instead of 
changing toolbar_item_type, which is not easily reachable from a gtkmm 
class, I've overridden the virtual function create_tool_item_vfunc().

I'm surprised that there is no GtkMenuToolAction class. (Or should it be 
called GtkToolMenuAction?)
I've found two bugs that discuss this matter.
