    public class QGraphicsSceneHelpEvent

extends QGraphicsSceneEvent

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.

  `QEvent`.
