§Properties

§linked

Readable

Object
§name

Readable | Writeable | Construct

§parent

The parent of the object. Please note, that when changing the ‘parent’ property, we don’t emit notify and deep-notify signals due to locking issues. In some cases one can use GstBin::element-added or GstBin::element-removed signals on the parent to achieve a similar effect.

Readable | Writeable

§Implements

gst::prelude::ObjectExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.
