/**
 * Java wrapper for Qt class QPropertyNotifier
 * The QPropertyNotifier class controls the lifecycle of change callback installed on a {@link QProperty}.
 * 
 * QPropertyNotifier is created when registering a callback on a QProperty to listen to changes to the property's value,
 * using {@link QProperty#addNotifier(Runnable)}.
 * As long as the notifier is alive i.e. as long as a reference to the QPropertyNotifier instance exists, the callback remains installed.
