%TRUE if the statusicon is embedded in a notification area.
The #GIcon displayed in the #GtkStatusIcon. For themed icons, the image will be updated automatically if the theme changes.
Enables or disables the emission of #GtkStatusIcon::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
#GtkStatusIcon::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 #GtkStatusIcon:tooltip-text in preference.
The orientation of the tray in which the statusicon is embedded.
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.
Sets the text of tooltip to be the given string, which is marked up with the [Pango text markup language][PangoMarkupFormat]. Also see gtk_tooltip_set_markup().
This is a convenience property which will take care of getting the tooltip shown if the given string is not %NULL. #GtkStatusIcon:has-tooltip will automatically be set to %TRUE and the default handler for the #GtkStatusIcon::query-tooltip signal will take care of displaying the tooltip.
On some platforms, embedded markup will be ignored.
Sets the text of tooltip to be the given string.
Also see gtk_tooltip_set_text().
This is a convenience property which will take care of getting the tooltip shown if the given string is not %NULL. #GtkStatusIcon:has-tooltip will automatically be set to %TRUE and the default handler for the #GtkStatusIcon::query-tooltip signal will take care of displaying the tooltip.
Note that some platforms have limitations on the length of tooltips that they allow on status icons, e.g. Windows only shows the first 64 characters.
Creates a binding between source_property on source and target_property
on target.
Whenever the source_property is changed the target_property is
updated using the same value. For instance:
g_object_bind_property (action, "active", widget, "sensitive", 0);
Will result in the "sensitive" property of the widget #GObject instance to be updated with the same value of the "active" property of the action #GObject instance.
If flags contains %G_BINDING_BIDIRECTIONAL then the binding will be mutual:
if target_property on target changes then the source_property on source
will be updated as well.
The binding will automatically be removed when either the source or the
target instances are finalized. To remove the binding without affecting the
source and the target you can just call g_object_unref() on the returned
#GBinding instance.
Removing the binding by calling g_object_unref() on it must only be done if
the binding, source and target are only used from a single thread and it
is clear that both source and target outlive the binding. Especially it
is not safe to rely on this if the binding, source or target can be
finalized from different threads. Keep another reference to the binding and
use g_binding_unbind() instead to be on the safe side.
A #GObject can have multiple bindings.

Creates a binding between source_property on source and target_property
on target, allowing you to set the transformation functions to be used by
the binding.

This function is intended for #GObject implementations to re-enforce a [floating][floating-ref] object reference. Doing this is seldom required: all #GInitiallyUnowneds are created with a floating reference which usually just needs to be sunken by calling g_object_ref_sink().
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. Duplicate notifications are squashed so that at most one
#GObject::notify signal is emitted for each property modified while the
object is frozen.
This is necessary for accessors that modify multiple properties to prevent premature notification while the object is still being modified.
Gets a named field from the objects table of associations (see g_object_set_data()).
name of the key for that association
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().
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;
Returns the current value of the has-tooltip property. See #GtkStatusIcon:has-tooltip for more information.
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.
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.
Gets a property of an object.
The value can be:
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.
the name of the property to get
return location for the property value
This function gets back user data pointers stored via g_object_set_qdata().
A #GQuark, naming the user data pointer
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()).
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.
Gets the title of this tray icon. See gtk_status_icon_set_title().
Gets the contents of the tooltip for status_icon.
Gets the contents of the tooltip for status_icon.
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().
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().
Gets n_properties properties for an object.
Obtained properties will be set to values. All properties must be valid.
Warnings will be emitted and undefined behaviour may result if invalid
properties are passed in.
the names of each property to get

Returns whether the status icon is embedded in a notification area.
Checks whether object has a [floating][floating-ref] reference.
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.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.
the name of a property installed on the class of object.
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 g_object_class_install_property() inside a static array, e.g.:
enum
{
PROP_0,
PROP_FOO,
PROP_LAST
};
static GParamSpec *properties[PROP_LAST];
static void
my_object_class_init (MyObjectClass *klass)
{
properties[PROP_FOO] = g_param_spec_int ("foo", "Foo", "The foo",
0, 100,
50,
G_PARAM_READWRITE);
g_object_class_install_property (gobject_class,
PROP_FOO,
properties[PROP_FOO]);
}
and then notify a change on the "foo" property with:
g_object_notify_by_pspec (self, properties[PROP_FOO]);
the #GParamSpec of a property installed on the class of object.
Increase the reference count of object, and possibly remove the
[floating][floating-ref] 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 GLib 2.56, the type of object will be propagated to the return type
under the same conditions as for g_object_ref().
Releases all references to other objects. This can be used to break reference cycles.
This function should only be called from object system implementations.
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.
Internally, the key is converted to a #GQuark using g_quark_from_string().
This means a copy of key is kept permanently (even after object has been
finalized) — so it is recommended to only use a small, bounded set of values
for key in your program, to avoid the #GQuark storage growing unbounded.

Remove a specified datum from the object's data associations, without invoking the association's destroy handler.
name of the key
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
user data pointers with a destroy notifier, for example:
void
object_add_to_user_list (GObject *object,
const gchar *new_string)
{
// the quark, naming the object data
GQuark quark_string_list = g_quark_from_static_string ("my-string-list");
// retrieve the old string list
GList *list = g_object_steal_qdata (object, quark_string_list);
// prepend new string
list = g_list_prepend (list, g_strdup (new_string));
// this changed 'list', so we need to set it again
g_object_set_qdata_full (object, quark_string_list, list, free_string_list);
}
static void
free_string_list (gpointer data)
{
GList *node, *list = data;
for (node = list; node; node = node->next)
g_free (node->data);
g_list_free (list);
}
Using g_object_get_qdata() in the above example, instead of g_object_steal_qdata() would have left the destroy function set, and thus the partial string list would have been freed upon g_object_set_qdata_full().
A #GQuark, naming the user data pointer
Reverts the effect of a previous call to
g_object_freeze_notify(). The freeze count is decreased on object
and when it reaches zero, queued "notify" signals are emitted.
Duplicate notifications for each property are squashed so that at most one #GObject::notify signal is emitted for each property, in the reverse order in which they have been queued.
It is an error to call this function when the freeze count is zero.
Decreases the reference count of object. When its reference count
drops to 0, the object is finalized (i.e. its memory is freed).
If the pointer to the #GObject may be reused in future (for example, if it is an instance variable of another object), it is recommended to clear the pointer to %NULL rather than retain a dangling pointer to a potentially invalid #GObject instance. Use g_clear_object() for this.
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.
Note that emission of the notify signal may be blocked with g_object_freeze_notify(). In this case, the signal emissions are queued and will be emitted (in reverse order) when g_object_thaw_notify() is called.
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.

name of a property to look up.
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.
If pspec is a floating reference, it will be consumed.
