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()
.
Parameters
status_icon |
||
screen |
return location for the screen, or |
[out][transfer none][allow-none] |
area |

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()
.
Since 2.14
Property Details
The “blinking”
property
“blinking” gboolean
Whether or not the status icon is blinking.
GtkStatusIcon:blinking
has been deprecated since version 2.22 and should not be used in newly-written code.
This property will be removed in GTK+ 3
Flags: Read / Write
Default value: FALSE
The “embedded”
property
“embedded” gboolean
TRUE
if the statusicon is embedded in a notification area.
Flags: Read
Default value: FALSE
Since 2.12
The “gicon”
property

The “has-tooltip”
property
“has-tooltip” gboolean
Enables or disables the emission of “query-tooltip” on

“query-tooltip” to determine whether it will provide a
tooltip or not.

to FALSE
again.
Whether this property is respected is platform dependent. For plain text tooltips, use “tooltip-text” in preference.

property
“tooltip-markup” gchar *
Sets the text of tooltip to be the given string, which is marked up
with the gtk_tooltip_set_markup()
.
This is a convenience property which will take care of getting the

“has-tooltip” will automatically be set to TRUE
and
the default handler for the “query-tooltip” signal
will take care of displaying the tooltip.
On some platforms, embedded markup will be ignored.
Flags: Read / Write

Signal Details
The “activate”
signal
void user_function (GtkStatusIcon *status_icon, gpointer user_data)
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.
Parameters
status_icon |
the object which received the signal |
|
user_data |
user data set when the signal handler was connected. |
Flags: Action
Since 2.10
The “button-press-event”
signal
gboolean user_function (GtkStatusIcon *status_icon, GdkEvent *event, gpointer user_data)
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.
Parameters
status_icon |
the object which received the signal |
|
event |
the GdkEventButton 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.
Flags: Run Last
Since 2.14
The “button-release-event”
signal
gboolean user_function (GtkStatusIcon *status_icon, GdkEvent *event, gpointer user_data)
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.
Parameters
status_icon |
the object which received the signal |
|
event |
the GdkEventButton 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.
Flags: Run Last
Since 2.14
The “popup-menu”
signal
void user_function (GtkStatusIcon *status_icon, guint button, guint activate_time, gpointer user_data)
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.
Parameters
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. |
Flags: Action
Since 2.10
The “query-tooltip”
signal
gboolean user_function (GtkStatusIcon *status_icon, gint x, gint y, gboolean keyboard_mode, GtkTooltip *tooltip, gpointer user_data)
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.
Parameters
status_icon |
the object which received the signal |
|
x |
the x coordinate of the cursor position where the request has been
emitted, relative to |
|
y |
the y coordinate of the cursor position where the request has been
emitted, relative to |
|
keyboard_mode |
|
|
tooltip |
||
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
Since 2.16
The “scroll-event”
signal
gboolean user_function (GtkStatusIcon *status_icon, GdkEvent *event, gpointer user_data)
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.
Parameters
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.
Flags: Run Last

Parameters
status_icon |
the object which received the signal |
|
size |
the new size |

user_data |
user data set when the signal handler was connected. |
