Now that menubar and menu are containers with internal structure, we need to be careful about doing the right thing in forall and dispose.

|
||
* @Title: GtkMenu
|
||
*
|
||
* 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.
|
||
*
|
||
* A #GtkMenu is most commonly dropped down by activating a
|
||
* #GtkMenuItem in a #GtkMenuBar or popped up by activating a
|
||
* #GtkMenuItem in another #GtkMenu.
|
||
*
|
||
* A #GtkMenu can also be popped up by activating a #GtkComboBox.
|
||
* Other composite widgets such as the #GtkNotebook can pop up a
|
||
* #GtkMenu as well.
|
||
*
|
||
* Applications can display a #GtkMenu as a popup menu by calling one of the
|
||
* gtk_menu_popup_*() function. The example below shows how an application can
|
||
* pop up a menu when the 3rd mouse button is pressed.
|
||
*
