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.

Obtains information about the location of the status icon on screen. This information can be used to e.g. position popups like notification bubbles.

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().

                                                        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,

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

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.
