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().

status_icon

a GtkStatusIcon

 

screen

return location for the screen, or NULL if the information is not needed.

[out][transfer none][allow-none]

area

Parameters

status_icon

a GtkStatusIcon

 

Returns

An 32 bit unsigned integer identifier for the underlying X11 Window

Since: 2.14

Types and Values

struct GtkStatusIcon

struct GtkStatusIcon;

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

Since: 2.14


The “has-tooltip” property

  “has-tooltip”              gboolean

Enables or disables the emission of “query-tooltip” on status_icon . A value of TRUE indicates that status_icon can have a tooltip, in this case the status icon will be queried using “query-tooltip” to determine whether it will provide a tooltip or not.

Note that setting this property to TRUE for the first time will change the event masks of the windows of this status icon to include leave-notify and motion-notify events. This will not be undone when the property is set to FALSE again.

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

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 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.

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


The “size-changed” signal

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

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

Parameters

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.

Flags: Run Last

Since: 2.10
