Detailed Description

The QDeclarativeCleanup provides a callback when a QDeclarativeEngine is deleted.

Warning

This function is not part of the public interface.

Any object that needs cleanup to occur before the QDeclarativeEngine's QScriptEngine is destroyed should inherit from QDeclarativeCleanup. The clear() virtual method will be called by QDeclarativeEngine just before it deletes the QScriptEngine.
