Detailed Description

The QGraphicsSceneHoverEvent class provides hover events in the graphics view framework.

Since

4.2

\inmodule QtWidgets

When a QGraphicsView receives a QHoverEvent event, it translates it into QGraphicsSceneHoverEvent. The event is then forwarded to the QGraphicsScene associated with the view.
