//: A drop down menu widget.
//- A {\class Gtk::Menu} is a {\class Gtk::MenuShell} that implements a drop
//- down menu consisting of a list of {\class Gtk::MenuItem} objects which
//- can be navigated and activated by the user to perform application functions.
//-
//- A {\class Gtk::Menu} is most commonly dropped down by activating a
//- {\class Gtk::MenuItem} in a {\class Gtk::MenuBar} or popped up by activating
//- a {\class Gtk::MenuItem} in another {\class Gtk::Menu}.
//-
//- A {\class Gtk::Menu} can also be popped up by activating a
//- {\class Gtk::OptionMenu}. Other composite widgets such as the
//- {\class Gtk::Notebook} can pop up a {\class Gtk::Menu} as well.
//-
//- Applications can display a {\class Gtk::Menu} as a popup menu by calling
//- the {menu_popup()} function.
