Problem If you have followed the previous few articles on GtkAction, in particular How to set up toolbar using GtkAction - Part 2 - add accelerators? and How to set up menu using GtkAction - Part 3 - add accelerators with labels? did they get you excited about using GtkAction?
If you think about it, the menu items and toolbars are actually overlapping in functions. Both allow the users to select some functions. They just appear in different forms — one as a menu, the other as tool buttons. Also, the menus are usually more comprehensive, showing the users all the available functions. The toolbar, on the hand, usually only shows the most commonly used functions.
As such, we can conveniently use GtkAction to create menus and toolbars together. This makes the maintenance and new additions of menu and toolbar items much easier as shown below:
Solution We use exactly the same techniques as outlined in How to set up toolbar using GtkAction - Part 2 - add accelerators? and How to set up menu using GtkAction - Part 3 - add accelerators with labels?
