    public class QGraphicsSceneWheelEvent

extends QGraphicsSceneEvent

The QGraphicsSceneWheelEvent class provides wheel events in the graphics view framework. he QGraphicsSceneWheelEvent class provides wheel events in the graphics view framework. `QWheelEvent`s received by a `QGraphicsView` are translated into QGraphicsSceneWheelEvents; it translates the `QWheelEvent::globalPos()` into item, scene, and screen coordinates (`pos()`, `scenePos()`, and `screenPos()`).

  `QGraphicsSceneMouseEvent`, `QGraphicsSceneContextMenuEvent`, `QGraphicsSceneHoverEvent`, and `QWheelEvent`.

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()`.

### setButtons

    public final void setButtons(Qt.MouseButton[] buttons)

### setModifiers

    public final void setModifiers(Qt.KeyboardModifier[] modifiers)

### toString

    public java.lang.String toString()

  Returns a string representation of the `this QGraphicsSceneWheelEvent`.

  Overrides:
    `toString` in class `QGraphicsSceneEvent`
