You will begin this chapter by learning how to create a pop-up menu. A pop-up menu is a Gtk::Menu widget that is displayed to the user when the right mouse button is clicked when hovering above certain widgets. Some widgets such as Gtk::Entry and Gtk::TextView, already have a pop-up menus built into the widget by default.
If you want to change the pop-up menu of a widget that offers one by default, you should edit the supplied Gtk::Menu widget in the pop-up callback proc or method. For example, both Gtk::Entry and Gtk::TextView have a ((*populate-popoup*)) signal, which receives the Gtk::Menu that is going to be displayed. You can edit this menu in any way you see fit before displaying it to the user.
