This module implements a TrayManager - an integral part of a Linux system tray widget, though it is not itself a widget. This package exports a single GObject (for use with gtk2hs) that implements the freedesktop.org system tray specification (it handles receiving events and translating them into convenient signals, along with the messy work of dealing with XEMBED).

The basic usage of the object is to:

1. Instantiate the object with trayManagerNew
2. Have it manage a specific screen with trayManagerManageScreen
3. Set up handlers for the events exposed by the tray (e.g., trayIconAdded).

As an example, a functional system tray widget looks something like:

import Graphics.UI.Gtk
import Graphics.UI.Gtk.Misc.TrayManager
systrayNew = do
  box <- hBoxNew False 5
  trayManager <- rayManagerNew
  Just screen <- screenGetDefault
  trayManagerManageScreen trayManager screen
  on trayManager trayIconAdded $ \w -> do
    widgetShowAll w
    boxPackStart box w PackNatural 0

Note that the widgets made available in the event handlers are not shown by default; you need to explicitly show them if you want that (and you probably do).
