/**
 * SECTION:gtkstatusicon
 * @Short_description: Display an icon in the system tray
 * @Title: GtkStatusIcon
 *
 * The "system tray" or notification area is normally used for transient icons
 * that indicate some special state. For example, a system tray icon might
 * appear to tell the user that they have new mail, or have an incoming instant
 * message, or something along those lines. The basic idea is that creating an
 * icon in the notification area is less annoying than popping up a dialog.
 *
 * A #GtkStatusIcon object can be used to display an icon in a "system tray".
 * The icon can have a tooltip, and the user can interact with it by
 * activating it or popping up a context menu. Critical information should
 * not solely be displayed in a #GtkStatusIcon, since it may not be
 * visible (e.g. when the user doesn't have a notification area on his panel).
 * This can be checked with gtk_status_icon_is_embedded().
 *
 * On X11, the implementation follows the freedesktop.org "System Tray"
 * <ulink url="http://www.freedesktop.org/wiki/Specifications/systemtray-spec">specification</ulink>.
 * Implementations of the "tray" side of this specification can
 * be found e.g. in the GNOME 2 and KDE panel applications.
 *
 * Note that a GtkStatusIcon is <emphasis>not</emphasis> a widget, but just
 * a #GObject. Making it a widget would be impractical, since the system tray
 * on Win32 doesn't allow to embed arbitrary widgets.
