Detailed Description
When a QGraphicsView receives a QHoverEvent event, it translates it into QGraphicsSceneHoverEvent. The event is then forwarded to the QGraphicsScene associated with the view.
See also QGraphicsSceneMouseEvent, QGraphicsSceneContextMenuEvent, QGraphicsSceneWheelEvent, and QHoverEvent.
Member Function Documentation
[explicit]
QGraphicsSceneHoverEvent::QGraphicsSceneHoverEvent(Type type = None)
\internal
Constructs a graphics scene hover event of the specified type.
[virtual noexcept]
QGraphicsSceneHoverEvent::~QGraphicsSceneHoverEvent()
Destroys the event.
QPointF QGraphicsSceneHoverEvent::lastPos() const
\since
4.4
Returns the last recorded mouse cursor position in item coordinates.
See also setLastPos(), lastScenePos(), lastScreenPos(), and pos().
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 setLastScenePos(), lastPos(), lastScreenPos(), and scenePos().
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.
See also setLastScreenPos(), lastPos(), lastScenePos(), and screenPos().
Qt::KeyboardModifiers QGraphicsSceneHoverEvent::modifiers() const
\since
4.4
Returns the keyboard modifiers at the moment the hover event was sent.
See also setModifiers().
QPointF QGraphicsSceneHoverEvent::pos() const
Returns the position of the mouse cursor in item coordinates at the moment the hover event was sent.
See also setPos(), scenePos(), and screenPos().
QPointF QGraphicsSceneHoverEvent::scenePos() const
Returns the position of the mouse cursor in scene coordinates at the moment the hover event was sent.
See also setScenePos(), pos(), and screenPos().
QPoint QGraphicsSceneHoverEvent::screenPos() const
Returns the position of the mouse cursor in screen coordinates at the moment the hover event was sent.
See also setScreenPos(), pos(), and scenePos().
void QGraphicsSceneHoverEvent::setLastPos(const QPointF &pos)
\internal
See also lastPos().
void QGraphicsSceneHoverEvent::setLastScenePos(const QPointF &pos)
\internal
See also lastScenePos().
void QGraphicsSceneHoverEvent::setLastScreenPos(const QPoint &pos)
\internal
See also lastScreenPos().
void QGraphicsSceneHoverEvent::setModifiers(Qt::KeyboardModifiers modifiers)
\internal
Sets the modifiers for the current hover event to modifiers.
See also modifiers().
void QGraphicsSceneHoverEvent::setPos(const QPointF &point)
\internal
Sets the position associated with the hover event to the given point in item coordinates.
See also pos().
void QGraphicsSceneHoverEvent::setScenePos(const QPointF &point)
\internal
Sets the position associated with the hover event to the given point in scene coordinates.
See also scenePos().
void QGraphicsSceneHoverEvent::setScreenPos(const QPoint &point)
\internal
Sets the position associated with the hover event to the given point in screen coordinates.
See also screenPos().
