Detailed Description

The QGraphicsSceneWheelEvent class provides wheel events in the graphics view framework.

QWheelEvents received by a QGraphicsView are translated into QGraphicsSceneWheelEvents; it translates the QWheelEvent::globalPos() into item, scene, and screen coordinates (pos(), scenePos(), and screenPos()).

See also QGraphicsSceneMouseEvent, QGraphicsSceneContextMenuEvent, QGraphicsSceneHoverEvent, and QWheelEvent.

Constructor & Destructor Documentation

protected
QtGui.QGraphicsSceneWheelEvent.QGraphicsSceneWheelEvent ( QEvent.Type  type = QEvent.Type.None)

Member Function Documentation

override void QtGui.QGraphicsSceneWheelEvent.CreateProxy ( )
virtual

Reimplemented from QtGui.QGraphicsSceneEvent.

new void QtGui.QGraphicsSceneWheelEvent.Dispose ( )

Property Documentation

new Qt.MouseButton QtGui.QGraphicsSceneWheelEvent.Buttons
getset

Returns the mouse buttons that were pressed when the wheel event occurred.

new int QtGui.QGraphicsSceneWheelEvent.Delta
getset

Returns the distance that the wheel is rotated, in eighths (1/8s) of a degree. A positive value indicates that the wheel was rotated forwards away from the user; a negative value indicates that the wheel was rotated backwards toward the user.

Most mouse types work in steps of 15 degrees, in which case the delta value is a multiple of 120 (== 15 * 8).

new Qt.KeyboardModifier QtGui.QGraphicsSceneWheelEvent.Modifiers
getset

Returns the keyboard modifiers that were active when the wheel event occurred.

new Qt.Orientation QtGui.QGraphicsSceneWheelEvent.Orientation
getset

Returns the wheel orientation.

new QPointF QtGui.QGraphicsSceneWheelEvent.Pos
getset

Returns the position of the cursor in item coordinates when the wheel event occurred.

new QPointF QtGui.QGraphicsSceneWheelEvent.ScenePos
getset

Returns the position of the cursor in scene coordinates when the wheel event occurred.

new QPoint QtGui.QGraphicsSceneWheelEvent.ScreenPos
getset

Returns the position of the cursor in screen coordinates when the wheel event occurred.
