public class QGraphicsSceneHelpEvent
The QGraphicsSceneHelpEvent class provides events when a tooltip is requested.
When a QGraphicsView receives a QEvent of type QEvent::ToolTip, it creates a QGraphicsSceneHelpEvent, which is forwarded to the scene. You can set a tooltip on a QGraphicsItem with setToolTip(); by default QGraphicsScene displays the tooltip of the QGraphicsItem with the highest z-value (i.e, the top-most item) under the mouse position.
QGraphicsView does not forward events when "What's This" and status tip help is requested. If you need this, you can reimplement QGraphicsView::viewportEvent() and forward QStatusTipEvent events and QEvents of type QEvent::WhatsThis to the scene.
