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.

Constructor & Destructor Documentation

◆ QGraphicsSceneHoverEvent()

QGraphicsSceneHoverEvent::QGraphicsSceneHoverEvent ( Type type = None )

explicit

Definition at line 1125 of file qgraphicssceneevent.cpp.

◆ ~QGraphicsSceneHoverEvent()

QGraphicsSceneHoverEvent::~QGraphicsSceneHoverEvent ( )

Destroys the event.

Member Function Documentation

◆ lastPos()

QPointF QGraphicsSceneHoverEvent::lastPos ( ) const

Since: 4.4

Returns the last recorded mouse cursor position in item coordinates.

See also: lastScenePos(), lastScreenPos(), pos()

Definition at line 1219 of file qgraphicssceneevent.cpp.

◆ lastScenePos()

QPointF QGraphicsSceneHoverEvent::lastScenePos ( ) const

Since: 4.4

Returns the last recorded, the scene coordinates of the previous mouse or hover event received by the view, that created the event mouse cursor position in scene coordinates.

See also: lastPos(), lastScreenPos(), scenePos()

Definition at line 1243 of file qgraphicssceneevent.cpp.

Here is the caller graph for this function:

◆ lastScreenPos()

QPoint QGraphicsSceneHoverEvent::lastScreenPos ( ) const

Since: 4.4

Returns the last recorded mouse cursor position in screen coordinates. The last recorded position is the position of the previous mouse or hover event received by the view that created the event.
