PyGI GtkStatusIcon Examples

Here is an example on how to build a GtkStatusIcon using PyGI (Python GObject). The code actually implements a libpeas plugin that could be used with any GTK+ project that allows GI plugins. The tray icon could respond to left clicking by toggling the application window like many instant messengers do. On right clicks it presents a menu with the options to toggle the application window or quit the application.
from gi.repository import GObject, Peas, PeasGtk, Gtk

class TrayiconPlugin (GObject.Object, PeasActivatable):
    __gtype_name__ = 'TrayiconPlugin'

    object = (type=GObject.Object)

    def do_activate (self):
        self.staticon = Gtk.StatusIcon ()
	self.staticon.set_from_stock (Gtk.STOCK_ABOUT)
        self.staticon.connect ("activate", self.trayicon_activate)
        self.staticon.connect ("popup_menu", self.trayicon_popup)
        self.staticon.set_visible (True)

    def trayicon_activate (self, widget, data = None):
        print "toggle app window!"

    def trayicon_quit (self, widget, data = None):
        print "quit app!"

    def trayicon_popup (self, widget, button, time, data = None): = Gtk.Menu ()

        menuitem_toggle = Gtk.MenuItem ("Show / Hide")
        menuitem_quit = Gtk.MenuItem ("Quit")

        menuitem_toggle.connect ("activate", self.trayicon_activate)
        menuitem_quit.connect ("activate", self.trayicon_quit) (menuitem_toggle) (menuitem_quit) (), None, lambda w,x: self.staticon.position_menu(, self.staticon), self.staticon, 3, time)

    def do_deactivate (self):
        self.staticon.set_visible (False)
        del self.staticon
