    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`
