abstract class for QEvent handlers

Author

Marco Vignati

QHandle is the abstract class for accessing QEvent QObject's in read (ReadHandle) and write (WriteHandle) mode. Each handle corresponds to a single QObject, and attempts to use the same handle for different QObject's will throw an exception.
