The QCustomEvent class provides support for custom events.
QCustomEvent has a void * that can be used to store custom data.
In Qt 3, QObject::customEvent() took a QCustomEvent pointer. We found out that this approach was unsatisfactory, because there was often no safe way of deleting the data held in the void *.
In Qt 4, QObject::customEvent() takes a plain QEvent pointer. You can add custom data by subclassing.
