## Description

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" specification. Implementations of the "tray" side of this specification can be found e.g. in the GNOME and KDE panel applications.

Note that a GtkStatusIcon is not 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.

See `gtk_status_icon_position_menu()` for a more convenient alternative for positioning menus.

Note that some platforms do not allow GTK+ to provide this information, and even on platforms that do allow it, the information is not reliable unless the status icon is embedded in a notification area, see `gtk_status_icon_is_embedded()`.

## Signal Details

### The `"activate"` signal

    void                user_function                      (GtkStatusIcon *status_icon,
                                                            gpointer       user_data)        : Run First / Action

Gets emitted when the user activates the status icon. If and how status icons can activated is platform-dependent.

`status_icon` : | the object which received the signal
`user_data` : | user data set when the signal handler was connected.

Since 2.10

### The `"popup-menu"` signal

    void                user_function                      (GtkStatusIcon *status_icon,
                                                            guint          button,
                                                            guint          activate_time,
                                                            gpointer       user_data)          : Run First / Action

Gets emitted when the user brings up the context menu of the status icon. Whether status icons can have context menus and how these are activated is platform-dependent.

The `button` and `activate_timeout` parameters should be passed as the last to arguments to `gtk_menu_popup()`.

`status_icon` : | the object which received the signal
`button` : | the button that was pressed, or 0 if the signal is not emitted in response to a button press event
`activate_time` : | the timestamp of the event that triggered the signal emission
`user_data` : | user data set when the signal handler was connected.

Since 2.10

### The `"size-changed"` signal

    gboolean            user_function                      (GtkStatusIcon *status_icon,
                                                            gint           size,
                                                            gpointer       user_data)        : Run Last

Gets emitted when the size available for the image changes, e.g. because the notification area got resized.

`status_icon` : | the object which received the signal
`size` : | the new size
`user_data` : | user data set when the signal handler was connected.
Returns : | `TRUE` if the icon was updated for the new size. Otherwise, GTK+ will scale the icon as necessary.

Since 2.10
