NAME

Gtk2::TrayManager - Perl bindings for EggTrayManager

SYNOPSIS

         use Gtk2 -init;
         use Gtk2::TrayManager;
 
         my $screen = Gtk2::Gdk::Screen->get_default;
 
         if (Gtk2::TrayManager->check_running($screen)) {
                 print STDERR "A tray manager is already running, sorry!\n";
                 exit 256;
         }
 
         my $tray = Gtk2::TrayManager->new;
         $tray->manage_screen($screen);
         $tray->set_orientation('vertical');
 
         $tray->signal_connect('tray_icon_added', sub {
                 # $_[1] is a Gtk2::Socket
         });
 
         $tray->signal_connect('tray_icon_removed', sub {
                 # $_[1] is a Gtk2::Socket
         });
 
 

ABSTRACT

The EggTrayManager library is used internally by GNOME to implement the server-side of the Notification Area (or system tray) protocol. Gtk2::TrayManager allows you to create notification area applications using Gtk2-Perl.

METHODS

         $running = Gtk2::TrayManager->check_running($screen);
 
 

This method returns a boolean value indicating whether another program is already managing notifications for the given Gtk2::Gdk::Screen. If this method returns a false value, then you should give way to the application that is already running.

         $tray = Gtk2::TrayManager->new;
 
 

This creates a tray manager object.

         $tray->manage_screen($screen);
 
 

This tells the tray to manage notifications for the Gtk2::Gdk::Screen referenced by $screen.

         $tray->set_orientation($orientation);
 
 

This method tells the tray whether icons are to be arranged vertically or horizontally. $orientation may be either '"vertical"' or '"horizontal"'.

         $title = $tray->get_child_title($child);
 
 

This method returns a string containing the title of the icon defined by $child.

SIGNALS

"tray_icon_added"

Emitted when a client plug (eg one created by Gtk2::TrayIcon) wants to connect. For callbacks connected to this signal, @_ will have the form

         @_ = (
                 bless( {}, 'Gtk2::TrayManager' ),
                 bless( {}, 'Gtk2::Socket' )
         );
 
 

"tray_icon_added"

Emitted when a client plug has disconnected. For callbacks connected to this signal, @_ will have the form

         @_ = (
                 bless( {}, 'Gtk2::TrayManager' ),
                 bless( {}, 'Gtk2::Socket' )
         );
 
 

"message_sent", "message_removed"

The Freedesktop.org specification includes support for ``balloon messages'', but these are not currently implemented in EggTrayManager.

"lost_selection"

As a rule, compliant applications should check to for an already running manager, and give way to it if it finds one. However, it is possible that your application might have its X selection forcibly removed; this signal is emitted if this should happen.
