Properties

"control-binding-added": (arg0: Gst.ControlBinding) => void

This is emitted when a control binding is added to a child property of the track element.

"control-binding-removed": (arg0: Gst.ControlBinding) => void

This is emitted when a control binding is removed from a child property of the track element.

Properties - Inherited from GES.TimelineElement.SignalSignatures

"child-property-added": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when the element has a new child property registered. See ges_timeline_element_add_child_property().

Note that some GES elements will be automatically created with pre-registered children properties. You can use ges_timeline_element_list_children_properties() to list these.

1.18

"child-property-removed": (
    arg0: GObject.Object,
    arg1: GObject.ParamSpec,
) => void

Emitted when the element has a child property unregistered. See ges_timeline_element_remove_child_property().

1.18

"deep-notify": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::duration": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::in-point": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::max-duration": (
    arg0: GObject.Object,
    arg1: GObject.ParamSpec,
) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::name": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::parent": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::priority": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::serialize": (
    arg0: GObject.Object,
    arg1: GObject.ParamSpec,
) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::start": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

"deep-notify::timeline": (arg0: GObject.Object, arg1: GObject.ParamSpec) => void

Emitted when a child of the element has one of its registered properties set. See ges_timeline_element_add_child_property(). Note that unlike GObject.Object::notify, a child property name can not be used as a signal detail.

notify: (arg0: GObject.ParamSpec) => void

The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.

Note that getting this signal doesn’t itself guarantee that the value of the property has actually changed. When it is emitted is determined by the derived GObject class. If the implementor did not create the property with GObject.ParamFlags.EXPLICIT_NOTIFY, then any call to g_object_set_property() results in ::notify being emitted, even if the new value is the same as the old. If they did pass GObject.ParamFlags.EXPLICIT_NOTIFY, then this signal is emitted only when they explicitly call g_object_notify() or g_object_notify_by_pspec(), and common practice is to do that only when the value has actually changed.

This signal is typically used to obtain change notification for a single property, by specifying the property name as a detail in the g_signal_connect() call, like this:

g_signal_connect (text_view->buffer, "notify::paste-target-list",
                  G_CALLBACK (gtk_text_view_target_list_notify),
                  text_view)

It is important to note that you must use [canonical parameter names][class@GObject.ParamSpec#parameter-names] as detail strings for the notify signal.
