NAME
PerlPanel::MenuBase - a base class for PerlPanel menu applets.
SYNOPSIS
package PerlPanel::Applet::MyMenu;
use base 'PerlPanel::MenuBase';
use strict;
sub create_menu {
my $self = shift;
$self->menu->append($self->menu_item(
'Hello World!',
$icon,
sub { print "Hello World!\n" }
));
return 1;
}
1;
DESCRIPTION
"PerlPanel::MenuBase" 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 "PerlPanel::MenuBase" 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.
USAGE
"PerlPanel::MenuBase" is a base class - that means, you must write a
Perl module that inherits from it. The "use base" line in the example
above is one way you can do this. Then you simply override the
"configure()" and "create_menu()" methods with your own.
STANDARD METHODS
$self->add_control_items;
This method appends the standard set of PerlPanel control options to
the menu. The menu will subsequently look like this:
| |
| ----------------------------- |
| Lock Screen |
| Run Program... |
| Take Screenshot... |
| ----------------------------- |
| Shut Down... |
| Reboot... |
| ----------------------------- |
| Configure... |
| Close Panel |
| Add To Panel > |
| ----------------------------- |
| About... |
+-------------------------------+
my $item = $self->menu_item($label, $icon, $callback);
This returns a ready-prepared Gtk2::ImageMenuItem. This method does a
lot of hard work for you - $label is set as the text label for the
item, and if defined, $callback is connected to the 'activate' signal.
$icon can be either a file, a "Gtk::Gdk::Pixbuf", or a stock ID.
"menu_item" will automagically resize the icon to fit in with the rest
of the menu.
my $icon = $self->get_icon($string, $is_submenu_parent);
This method is deprecated and is no longer available. Use
PerlPanel::lookup_icon() instead.
