public class QGraphicsSceneWheelEvent
extends QGraphicsSceneEvent

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

buttons

public final Qt.MouseButtons buttons()

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

See also:

modifiers().

delta

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).

modifiers

public final Qt.KeyboardModifiers modifiers()

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

See also:

buttons().

orientation

public final Qt.Orientation orientation()

Returns the wheel orientation.

pos

public final QPointF pos()

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

See also:

scenePos(), and screenPos().

scenePos

public final QPointF scenePos()

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

See also:

pos(), and screenPos().

screenPos

public final QPoint screenPos()

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

See also:

pos(), and scenePos().

fromNativePointer

public static QGraphicsSceneWheelEvent fromNativePointer(QNativePointer nativePointer)

This method returns the QGraphicsSceneWheelEvent instance pointed to by nativePointer.

toString

public java.lang.String toString()

Returns a string representation of the this QGraphicsSceneWheelEvent.

Overrides:
