- All Implemented Interfaces:

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.
