Sets our main struct and passes it to the parent class
Creates a status icon displaying a stock icon. Sample stock icon names are StockID.OPEN, StockID.QUIT. You can register your own stock icon names, see gtk_icon_factory_add_default() and gtk_icon_factory_add(). Since 2.10
Creates a status icon displaying an icon from the current icon theme. If the current icon theme is changed, the icon will be updated appropriately. Since 2.10
Creates an empty status icon object. Since 2.10
Creates a status icon displaying pixbuf. The image will be scaled down to fit in the available space in the notification area, if necessary. Since 2.10
Creates a status icon displaying a GIcon. If the icon is a themed icon, it will be updated when the theme changes. Since 2.14
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. Since 2.10
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. 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 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. TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further. Since 2.14
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. Since 2.10
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. TRUE if the tooltip was trigged using the keyboard TRUE if tooltip should be shown right now, FALSE otherwise. Since 2.16
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. TRUE to stop other handlers from being invoked for the event. FALSE to propagate the event further.
Gets emitted when the size available for the image changes, e.g. because the notification area got resized. TRUE if the icon was updated for the new size. Otherwise, GTK+ will scale the icon as necessary. Since 2.10
Warning gtk_status_icon_get_blinking has been deprecated since version 2.22 and should not be used in newly-written code. This function will be removed in GTK+ 3 Returns whether the icon is blinking, see gtk_status_icon_set_blinking(). Since 2.10
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(). Since 2.10
Retrieves the GIcon being displayed by the GtkStatusIcon. The storage type of the status icon must be GTK_IMAGE_EMPTY or GTK_IMAGE_GICON (see gtk_status_icon_get_storage_type()). The caller of this function does not own a reference to the returned GIcon. If this function fails, icon is left unchanged; Since 2.14
Returns the current value of the has-tooltip property. See "has-tooltip" for more information. Since 2.16
Gets the name of the icon being displayed by the GtkStatusIcon. The storage type of the status icon must be GTK_IMAGE_EMPTY or GTK_IMAGE_ICON_NAME (see gtk_status_icon_get_storage_type()). The returned string is owned by the GtkStatusIcon and should not be freed or modified. Since 2.10
Gets the GdkPixbuf being displayed by the GtkStatusIcon. The storage type of the status icon must be GTK_IMAGE_EMPTY or GTK_IMAGE_PIXBUF (see gtk_status_icon_get_storage_type()). The caller of this function does not own a reference to the returned pixbuf. Since 2.10
Returns the GdkScreen associated with status_icon. Since 2.12
Gets the size in pixels that is available for the image. Stock icons and named icons adapt their size automatically if the size of the notification area changes. For other storage types, the size-changed signal can be used to react to size changes. Note that the returned size is only meaningful while the status icon is embedded (see gtk_status_icon_is_embedded()). Since 2.10
Gets the id of the stock icon being displayed by the GtkStatusIcon. The storage type of the status icon must be GTK_IMAGE_EMPTY or GTK_IMAGE_STOCK (see gtk_status_icon_get_storage_type()). The returned string is owned by the GtkStatusIcon and should not be freed or modified. Since 2.10
Gets the type of representation being used by the GtkStatusIcon to store image data. If the GtkStatusIcon has no image data, the return value will be GTK_IMAGE_EMPTY. Since 2.10
the main Gtk struct as a void*
Gets the title of this tray icon. See gtk_status_icon_set_title(). Since 2.18
Gets the contents of the tooltip for status_icon. Since 2.16
Gets the contents of the tooltip for status_icon. Since 2.16
Returns whether the status icon is visible or not. Note that being visible does not guarantee that the user can actually see the icon, see also gtk_status_icon_is_embedded(). Since 2.10
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
Returns whether the status icon is embedded in a notification area. Since 2.10
Warning gtk_status_icon_set_blinking has been deprecated since version 2.22 and should not be used in newly-written code. This function will be removed in GTK+ 3 Makes the status icon start or stop blinking. Note that blinking user interface elements may be problematic for some users, and thus may be turned off, in which case this setting has no effect. Since 2.10
Makes status_icon display the file filename. See gtk_status_icon_new_from_file() for details. Since 2.10
Makes status_icon display the GIcon. See gtk_status_icon_new_from_gicon() for details. Since 2.14
Makes status_icon display the icon named icon_name from the current icon theme. See gtk_status_icon_new_from_icon_name() for details. Since 2.10
Makes status_icon display pixbuf. See gtk_status_icon_new_from_pixbuf() for details. Since 2.10
Makes status_icon display the stock icon with the id stock_id. See gtk_status_icon_new_from_stock() for details. Since 2.10
Sets the has-tooltip property on status_icon to has_tooltip. See "has-tooltip" for more information. Since 2.16
Sets the name of this tray icon. This should be a string identifying this icon. It is may be used for sorting the icons in the tray and will not be shown to the user. Since 2.20
Sets the GdkScreen where status_icon is displayed; if the icon is already mapped, it will be unmapped, and then remapped on the new screen. Since 2.12
Sets the title of this tray icon. This should be a short, human-readable, localized string describing the tray icon. It may be used by tools like screen readers to render the tray icon. Since 2.18
Warning gtk_status_icon_set_tooltip has been deprecated since version 2.16 and should not be used in newly-written code. Use gtk_status_icon_set_tooltip_text() instead. Sets the tooltip of the status icon. Since 2.10
Sets markup as the contents of the tooltip, which is marked up with the Pango text markup language. This function will take care of setting "has-tooltip" to TRUE and of the default handler for the "query-tooltip" signal. See also the "tooltip-markup" property and gtk_tooltip_set_markup(). Since 2.16
Sets text as the contents of the tooltip. This function will take care of setting "has-tooltip" to TRUE and of the default handler for the "query-tooltip" signal. See also the "tooltip-text" property and gtk_tooltip_set_text(). Since 2.16
Shows or hides a status icon. Since 2.10
Menu positioning function to use with gtk_menu_popup() to position menu aligned to the status icon user_data. Since 2.10
the main Gtk struct
the main Gtk struct
the main Gtk struct as a void*
Gets a D Object from the objects table of associations.
The notify signal is emitted on an object when one of its properties has been changed. Note that getting this signal doesn't guarantee that the value of the property has actually changed, it may also be emitted when the setter for the property is called to reinstate the previous value. This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the It is important to note that you must use canonical parameter names as detail strings for the notify signal. See Also GParamSpecObject, g_param_spec_object()
Installs a new property. This is usually done in the class initializer. Note that it is possible to redefine a property in a derived class, by installing a property with the same name. This can be useful at times, e.g. to change the range of allowed values or the default value.
Installs new properties from an array of GParamSpecs. This is usually done in the class initializer. The property id of each property is the index of each GParamSpec in the pspecs array. The property id of 0 is treated specially by GObject and it should not be used to store a GParamSpec. This function should be used if you plan to use a static array of GParamSpecs and g_object_notify_by_pspec(). For instance, this Since 2.26
Looks up the GParamSpec for a property of a class.
Get an array of GParamSpec* for all properties of a class.
Registers property_id as referring to a property with the name name in a parent class or in an interface implemented by oclass. This allows this class to override a property implementation in a parent class or to provide the implementation of a property from an interface. Note Internally, overriding is implemented by creating a property of type GParamSpecOverride; generally operations that query the properties of the object class, such as g_object_class_find_property() or g_object_class_list_properties() will return the overridden property. However, in one case, the construct_properties argument of the constructor virtual function, the GParamSpecOverride is passed instead, so that the param_id field of the GParamSpec will be correct. For virtually all uses, this makes no difference. If you need to get the overridden property, you can call g_param_spec_get_redirect_target(). Since 2.4
Add a property to an interface; this is only useful for interfaces that are added to GObject-derived types. Adding a property to an interface forces all objects classes with that interface to have a compatible property. The compatible property could be a newly created GParamSpec, but normally g_object_class_override_property() will be used so that the object class only needs to provide an implementation and inherits the property description, default value, bounds, and so forth from the interface property. This function is meant to be called from the interface's default vtable initialization function (the class_init member of GTypeInfo.) It must not be called after after class_init has been called for any object types implementing this interface. Since 2.4
Find the GParamSpec with the given name for an interface. Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek(). Since 2.4
Lists the properties of an interface.Generally, the interface vtable passed in as g_iface will be the default vtable from g_type_default_interface_ref(), or, if you know the interface has already been loaded, g_type_default_interface_peek(). Since 2.4
Increases the reference count of object.
Decreases the reference count of object. When its reference count drops to 0, the object is finalized (i.e. its memory is freed).
Increase the reference count of object, and possibly remove the floating reference, if object has a floating reference. In other words, if the object is floating, then this call "assumes ownership" of the floating reference, converting it to a normal reference by clearing the floating flag while leaving the reference count unchanged. If the object is not floating, then this call adds a new normal reference increasing the reference count by one. Since 2.10
Clears a reference to a GObject. object_ptr must not be NULL. If the reference is NULL then this function does nothing. Otherwise, the reference count of the object is decreased and the pointer is set to NULL. This function is threadsafe and modifies the pointer atomically, using memory barriers where needed. A macro is also included that allows this function to be used without pointer casts. Since 2.28
Checks whether object has a floating reference. Since 2.10
This function is intended for GObject implementations to re-enforce a floating object reference. Doing this is seldomly required: all GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink(). Since 2.10
Adds a weak reference callback to an object. Weak references are used for notification when an object is finalized. They are called "weak references" because they allow you to safely hold a pointer to an object without calling g_object_ref() (g_object_ref() adds a strong reference, that is, forces the object to stay alive).
Removes a weak reference callback to an object.
Adds a weak reference from weak_pointer to object to indicate that the pointer located at weak_pointer_location is only valid during the lifetime of object. When the object is finalized, weak_pointer will be set to NULL.
Removes a weak reference from object that was previously added using g_object_add_weak_pointer(). The weak_pointer_location has to match the one used with g_object_add_weak_pointer().
Increases the reference count of the object by one and sets a callback to be called when all other references to the object are dropped, or when this is already the last reference to the object and another reference is established. This functionality is intended for binding object to a proxy object managed by another memory manager. This is done with two paired references: the strong reference added by g_object_add_toggle_ref() and a reverse reference to the proxy object which is either a strong reference or weak reference. The setup is that when there are no other references to object, only a weak reference is held in the reverse direction from object to the proxy object, but when there are other references held to object, a strong reference is held. The notify callback is called when the reference from object to the proxy object should be toggled from strong to weak (is_last_ref true) or weak to strong (is_last_ref false). Since a (normal) reference must be held to the object before calling g_object_toggle_ref(), the initial state of the reverse link is always strong. Multiple toggle references may be added to the same gobject, however if there are multiple toggle references to an object, none of them will ever be notified until all but one are removed. For this reason, you should only ever use a toggle reference if there is important state in the proxy object. Since 2.8
Removes a reference added with g_object_add_toggle_ref(). The reference count of the object is decreased by one. Since 2.8
Emits a "notify" signal for the property property_name on object. When possible, eg. when signaling a property change from within the class that registered the property, you should use g_object_notify_by_pspec() instead.
Emits a "notify" signal for the property specified by pspec on object. This function omits the property name lookup, hence it is faster than g_object_notify(). One way to avoid using g_object_notify() from within the class that registered the properties, and using g_object_notify_by_pspec() instead, is to store the GParamSpec used with Since 2.26
Increases the freeze count on object. If the freeze count is non-zero, the emission of "notify" signals on object is stopped. The signals are queued until the freeze count is decreased to zero. This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Reverts the effect of a previous call to g_object_freeze_notify(). The freeze count is decreased on object and when it reaches zero, all queued "notify" signals are emitted. It is an error to call this function when the freeze count is zero.
Gets a named field from the objects table of associations (see g_object_set_data()).
Each object carries around a table of associations from strings to pointers. This function lets you set an association. If the object already had an association with that name, the old association will be destroyed.
Like g_object_set_data() except it adds notification for when the association is destroyed, either by setting it to a different value or when the object is destroyed. Note that the destroy callback is not called if data is NULL.
Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
This function gets back user data pointers stored via g_object_set_qdata().
This sets an opaque, named pointer on an object. The name is specified through a GQuark (retrived e.g. via g_quark_from_static_string()), and the pointer can be gotten back from the object with g_object_get_qdata() until the object is finalized. Setting a previously set user data pointer, overrides (frees) the old pointer set, using NULL as pointer essentially removes the data stored.
This function works like g_object_set_qdata(), but in addition, a void (*destroy) (gpointer) function may be specified which is called with data as argument when the object is finalized, or the data is being overwritten by a call to g_object_set_qdata() with the same quark.
This function gets back user data pointers stored via g_object_set_qdata() and removes the data from object without invoking its destroy() function (if any was set). Usually, calling this function is only required to update
Sets a property on an object.
Gets a property of an object. value must have been initialized to the expected type of the property (or a type to which the expected type can be transformed) using g_value_init(). In general, a copy is made of the property contents and the caller is responsible for freeing the memory by calling g_value_unset(). Note that g_object_get_property() is really intended for language bindings, g_object_get() is much more convenient for C programming.
Sets properties on an object.
Gets properties of an object. In general, a copy is made of the property contents and the caller is responsible for freeing the memory in the appropriate manner for the type, for instance by calling g_free() or g_object_unref(). See g_object_get().
This function essentially limits the life time of the closure to the life time of the object. That is, when the object is finalized, the closure is invalidated by calling g_closure_invalidate() on it, in order to prevent invocations of the closure with a finalized (nonexisting) object. Also, g_object_ref() and g_object_unref() are added as marshal guards to the closure, to ensure that an extra reference count is held on object during invocation of the closure. Usually, this function will be called on closures that use this object as closure data.
Releases all references to other objects. This can be used to break reference cycles. This functions should only be called from object system implementations.
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.
