public class QGraphicsSceneMouseEvent
extends QGraphicsSceneEvent

The QGraphicsSceneMouseEvent class provides mouse events in the graphics view framework. When a QGraphicsView receives a QMouseEvent, it translates it to a QGraphicsSceneMouseEvent. The event is then forwarded to the QGraphicsScene associated with the view.

In addition to containing the item, scene, and screen coordinates of the event (as pos(), scenePos(), and screenPos()), mouse events also contain the coordinates of the previous mouse event received by the view. These can be retrieved with lastPos(), lastScreenPos(), and lastScenePos().

QGraphicsSceneContextMenuEvent, QGraphicsSceneHoverEvent, QGraphicsSceneWheelEvent, and QMouseEvent.

Returns the mouse cursor position in item coordinates where the specified button was clicked.

See also:

buttonDownScenePos(), buttonDownScreenPos(), and pos().

buttonDownScenePos

public final QPointF buttonDownScenePos(Qt.MouseButton button)

Returns the mouse cursor position in scene coordinates where the specified button was clicked.

See also:

buttonDownPos(), buttonDownScreenPos(), and scenePos().

buttonDownScreenPos

public final QPoint buttonDownScreenPos(Qt.MouseButton button)

Returns the mouse cursor position in screen coordinates where the specified button was clicked.

See also:

screenPos(), buttonDownPos(), and buttonDownScenePos().

buttons
