NAME

App::Chart::Gtk2::Ex::MenuItem::EmptyInsensitive -- menu item insensitive when submenu empty

SYNOPSIS

 use App::Chart::Gtk2::Ex::MenuItem::EmptyInsensitive;

 my $item = Gtk2::MenuItem->new;
 App::Chart::Gtk2::Ex::MenuItem::EmptyInsensitive->setup ($item);

DESCRIPTION

App::Chart::Gtk2::Ex::MenuItem::EmptyInsensitive sets up a Gtk2::MenuItem so that it's insensitive if its submenu is empty, or all the items are hidden, or there's no submenu set at all.

Sensitivity updates with items added or removed from the submenu, or made hidden or visible. In Gtk 2.12 and the sensitivity is updated for a new submenu, ie. set_submenu, but in prior versions there's no signal when that happens and you must call setup below again.

FUNCTIONS

App::Chart::Gtk2::Ex::MenuItem::EmptyInsensitive->setup ($item)

Setup $item to be insensitive if its submenu is empty.
