List of all members.

## Public Member Functions
virtual | ~OverlayElementFactory ()
| Destroy the overlay element factory.
virtual OverlayElement * | createOverlayElement (const String &instanceName)=0
| Creates a new OverlayElement instance with the name supplied.
virtual void | destroyOverlayElement (OverlayElement *pElement)
| Destroys a OverlayElement which this factory created previously.
virtual const String & | getTypeName (void) const =0
| Gets the string uniquely identifying the type of element this factory creates.

## Detailed Description

Defines the interface which all components wishing to supply OverlayElement subclasses must implement.

Remarks:
  To allow the OverlayElement types available for inclusion on overlays to be extended, OGRE allows external apps or plugins to register their ability to create custom OverlayElements with the OverlayManager, using the addOverlayElementFactory method. Classes wanting to do this must implement this interface.

  Each OverlayElementFactory creates a single type of OverlayElement, identified by a 'type name' which must be unique.
