##### Properties inherited from GstObject (2)

###### Gst.Object:name

No description available.

###### Gst.Object:parent

The parent of the object. Please note, that when changing the ‘parent’ property, we don’t emit `GObject::notify` and `GstObject::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.

#### Signals

##### Signals inherited from GstObject (1)

###### GstObject::deep-notify

The deep notify signal is used to be notified of property changes. It is typically attached to the toplevel bin to receive notifications from all the elements contained in that bin.

##### Signals inherited from GObject (1)

###### GObject::notify

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.

##### Signals inherited from GListModel (1)

###### GListModel::items-changed

This signal is emitted whenever items were added to or removed from `list`. At `position`, `removed` items were removed and `added` items were added in their place.
