The Qt Documentation states that a NOTIFY "signal must take one parameter, which must be of the same type as the property" [1]. If there are no good reasons the public classes should follow this pattern:
- Change NOTIFY signals of QmlGraphicsItem to include the changed value of a parameter.
 - Maybe remove the NOTIFY for the properties in QmlComponent that share the "statusChanged" signal.
