.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`PerlPanel::MenuBase\*(C'\fR is a base class that does as much as possible to
abstract the nuts-and-bolts details of building a PerlPanel menu applet. If you
use \f(CW\*(C`PerlPanel::MenuBase\*(C'\fR to write a menu applet, you don't need to worry
about menu hierarchies or icons \- all that's done for you. Instead to can
concentrate on building your menu backend.
.SH "USAGE"
.IX Header "USAGE"
\&\f(CW\*(C`PerlPanel::MenuBase\*(C'\fR is a base class \- that means, you must write a Perl
module that inherits from it. The \f(CW\*(C`use base\*(C'\fR line in the example above is one
way you can do this. Then you simply override the \f(CW\*(C`configure()\*(C'\fR and
\&\f(CW\*(C`create_menu()\*(C'\fR methods with your own.

This method appends the standard set of PerlPanel control options to the
menu. The menu will subsequently look like this:

.PP
This returns a ready-prepared Gtk2::ImageMenuItem. This method does a lot of
hard work for you \- \f(CW$label\fR is set as the text label for the item, and if
defined, \f(CW$callback\fR is connected to the \f(CW\*(Aqactivate\*(Aq\fR signal.
.PP
\&\f(CW$icon\fR can be either a file, a \f(CW\*(C`Gtk::Gdk::Pixbuf\*(C'\fR, or a stock \s-1ID.
\&\s0\f(CW\*(C`menu_item\*(C'\fR will automagically resize the icon to fit in with the rest of
the menu.

\&        my $icon = $self\->get_icon($string, $is_submenu_parent);
.Ve

This method is deprecated and is no longer available. Use \fIPerlPanel::lookup_icon()\fR instead.
