|
|
* in the case where you want the name of a child property to be

|
* 'overriden'. A good example of where it is usefull is the

* GESTitleSource where we have a videotestsrc which has a

|
* 'foreground-color' property that is used in the TitleSource to
|
|
* set the background color of the title, in that case, this method
|
|
* has been overriden so that we tweak the name passed has parametter
|
|
* to rename "background" to "foreground-backend" making our API
|
|
* understandable.
|
|
* Deprecated: use GESTimelineElement.lookup_child instead
|
|
*
|
|
* Subclasses can override the @create_gnl_object method to override what type
|
|
* of GNonLin object will be created.
