commit 5b3012835745c7979ea0bee486adc9f37c75d778
Author: Kjell Ahlstedt <kjell ahlstedt bredband net>
Date: Tue Nov 25 08:34:51 2014 +0100
Main menu example: Use Gtk::Application to display an app menu
* examples/Makefile.am: Add main_menu/exampleapplication.[h|cc].
* examples/book/menus/main_menu/exampleapplication.[h|cc]: New files.
* examples/book/menus/main_menu/examplewindow.[h|cc]:
* examples/book/menus/main_menu/main.cc: Derive from Gtk::Application and
Gtk::ApplicationWindow, similar to the application/app_and_win_menus example.
Thanks to Jürgen Kleber, who attached similar code to
https://mail.gnome.org/archives/gtkmm-list/2014-November/msg00012.html
