## 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 2 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.

### gtk_status_icon_get_x11_window_id ()

    guint32             gtk_status_icon_get_x11_window_id   (GtkStatusIcon *status_icon);

This function is only useful on the X11/freedesktop.org platform. It returns a window ID for the widget in the underlying status icon implementation. This is useful for the Galago notification service, which can send a window ID in the protocol in order for the server to position notification windows pointing to a status icon reliably.

This function is not intended for other use cases which are more likely to be met by one of the non-X11 specific methods, such as `gtk_status_icon_position_menu()`.

`status_icon` : | a GtkStatusIcon
Returns : | An 32 bit unsigned integer identifier for the underlying X11 Window

Since 2.14

                                                            gpointer       user_data)        : Action

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

Unlike most G_SIGNAL_ACTION signals, this signal is meant to be used by applications and should be wrapped by language bindings.

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

Since 2.10

### The `"button-press-event"` signal

    gboolean            user_function                      (GtkStatusIcon *status_icon,

The ::button-press-event signal will be emitted when a button (typically from a mouse) is pressed.

Whether this event is emitted is platform-dependent. Use the ::activate and ::popup-menu signals in preference.

`status_icon` : | the object which received the signal
`event` : | the GdkEventButton which triggered this signal. [type Gdk.EventButton]
`user_data` : | user data set when the signal handler was connected.
Returns : | `TRUE` to stop other handlers from being invoked for the event. `FALSE` to propagate the event further.

Since 2.14

### The `"button-release-event"` signal

    gboolean            user_function                      (GtkStatusIcon *status_icon,

The ::button-release-event signal will be emitted when a button (typically from a mouse) is released.

Whether this event is emitted is platform-dependent. Use the ::activate and ::popup-menu signals in preference.

`status_icon` : | the object which received the signal
`event` : | the GdkEventButton which triggered this signal. [type Gdk.EventButton]
`user_data` : | user data set when the signal handler was connected.
Returns : | `TRUE` to stop other handlers from being invoked for the event. `FALSE` to propagate the event further.

Since 2.14

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

    void                user_function                      (GtkStatusIcon *status_icon,
                                                            guint          button,
                                                            guint          activate_time,

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_time` parameters should be passed as the last to arguments to `gtk_menu_popup()`.

Unlike most G_SIGNAL_ACTION signals, this signal is meant to be used by applications and should be wrapped by language bindings.

`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 `"query-tooltip"` signal

    gboolean            user_function                      (GtkStatusIcon *status_icon,
                                                            gint           x,
                                                            gint           y,
                                                            gboolean       keyboard_mode,

Emitted when the "gtk-tooltip-timeout" has expired with the cursor hovering above `status_icon`; or emitted when `status_icon` got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for `status_icon`. If this is the case `TRUE` should be returned, `FALSE` otherwise. Note that if `keyboard_mode` is `TRUE`, the values of `x` and `y` are undefined and should not be used.

The signal handler is free to manipulate `tooltip` with the therefore destined function calls.

Whether this signal is emitted is platform-dependent. For plain text tooltips, use "tooltip-text" in preference.

`status_icon` : | the object which received the signal
`x` : | the x coordinate of the cursor position where the request has been emitted, relative to `status_icon`
`y` : | the y coordinate of the cursor position where the request has been emitted, relative to `status_icon`
`keyboard_mode` : | `TRUE` if the tooltip was trigged using the keyboard
`tooltip` : | a GtkTooltip
`user_data` : | user data set when the signal handler was connected.
Returns : | `TRUE` if `tooltip` should be shown right now, `FALSE` otherwise.

Since 2.16

### The `"scroll-event"` signal

    gboolean            user_function                      (GtkStatusIcon *status_icon,

                                                            gpointer       user_data)        : Run Last

The ::scroll-event signal is emitted when a button in the 4 to 7 range is pressed. Wheel mice are usually configured to generate button press events for buttons 4 and 5 when the wheel is turned.

Whether this event is emitted is platform-dependent.

`status_icon` : | the object which received the signal.
`event` : | the GdkEventScroll which triggered this signal. [type Gdk.EventScroll]
`user_data` : | user data set when the signal handler was connected.
Returns : | `TRUE` to stop other handlers from being invoked for the event. `FALSE` to propagate the event further.

Since 2.16

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

    gboolean            user_function                      (GtkStatusIcon *status_icon,

                                                            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
