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().

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

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 :

user_data :

user data set when the signal handler was connected.

Returns :

TRUE if tooltip should be shown right now, FALSE otherwise.

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

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.
