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

Method Detail |

public final Qt.MouseButtons buttons()
Returns the mouse buttons that were pressed when the wheel event occurred.
public final int delta()
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).
public final Qt.KeyboardModifiers modifiers()
Returns the keyboard modifiers that were active when the wheel event occurred.
public final Qt.Orientation orientation()
Returns the wheel orientation.
public final QPointF pos()
Returns the position of the cursor in item coordinates when the wheel event occurred.
public final QPointF scenePos()
Returns the position of the cursor in item coordinates when the wheel event occurred.
public final QPoint screenPos()
Returns the position of the cursor in screen coordinates when the wheel event occurred.
public final void setButtons(Qt.MouseButton... buttons)
public final void setButtons(Qt.MouseButtons buttons)
public final void setDelta(int delta)

public final void setPos(QPointF pos)
public final void setScenePos(QPointF pos)
public final void setScreenPos(QPoint pos)
public static QGraphicsSceneWheelEvent fromNativePointer(QNativePointer nativePointer)
nativePointer
- the QNativePointer of which object should be returned.
