NAME

6       Gtk2::MenuItem - wrapper for GtkMenuItem
7

DESCRIPTION

9       If a MenuItem is created with a $label string, or if the "label"
10       property is set later, then it should be destroyed with
11       "$item->destroy".  Just dropping the last Perl ref is not enough
12       because (as of Gtk through to 2.18) there's a circular reference from
13       the child "Gtk2::AccelLabel" back up to the item (the "accel-widget"
14       property).
15
16       When a MenuItem is in a "Gtk2::Menu" a "destroy" happens automatically.
17       Dropping the last ref to a Menu calls "destroy" on its children, as
18       usual for a container.  But if you remove a MenuItem with a label from
19       a menu (or never add it to one) then be sure to "$item->destroy"
20       explicitly.
