^{[QtGui module]}

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

Inherits QGraphicsSceneEvent.

Methods

• Qt.MouseButtons buttons (self)
• int delta (self)
• Qt.KeyboardModifiers modifiers (self)
• Qt.Orientation orientation (self)
• QPointF pos (self)
• QPointF scenePos (self)
• QPoint screenPos (self)

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 Documentation

Qt.MouseButtons QGraphicsSceneWheelEvent.buttons (self)

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

See also modifiers().

int QGraphicsSceneWheelEvent.delta (self)

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.

Qt.KeyboardModifiers QGraphicsSceneWheelEvent.modifiers (self)

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

See also buttons().

Qt.Orientation QGraphicsSceneWheelEvent.orientation (self)

Returns the wheel orientation.

QPointF QGraphicsSceneWheelEvent.pos (self)

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

See also scenePos() and screenPos().

QPointF QGraphicsSceneWheelEvent.scenePos (self)

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

See also pos() and screenPos().

QPoint QGraphicsSceneWheelEvent.screenPos (self)

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

See also pos() and scenePos().
