|
A #GtkMenu is a #GtkMenuShell that implements a drop down menu consisting of
|
|
a list of #GtkMenuItem objects which can be navigated and activated by the
|
|
user to perform application functions.
|
|
</para>
|
|
|
|
<para>
|
|
A #GtkMenu is most commonly dropped down by activating a #GtkMenuItem in a
|
|
#GtkMenuBar or popped up by activating a #GtkMenuItem in another #GtkMenu.
|
|
</para>
|
|
|
|
<para>
|
|
A #GtkMenu can also be popped up by activating a #GtkOptionMenu.
|
|
Other composite widgets such as the #GtkNotebook can pop up a #GtkMenu
|
|
as well.
|
|
</para>
|
|
|
|
<para>
|
|
Applications can display a #GtkMenu as a popup menu by calling the
|
|
gtk_menu_popup() function. The example below shows how an application
|
|
can pop up a menu when the 3rd mouse button is pressed.
