成员函数文档编制

QMouseEventTransition:: QMouseEventTransition ( QState * sourceState = 0)

Constructs a new mouse event transition with the given sourceState .

QMouseEventTransition:: QMouseEventTransition ( QObject * object , QEvent::Type type , Qt::MouseButton button , QState * sourceState = 0)

Constructs a new mouse event transition for events of the given type 为给定 object ，采用给定 button and sourceState .

QMouseEventTransition:: ~QMouseEventTransition ()

Destroys this mouse event transition.

[virtual protected] bool QMouseEventTransition:: eventTest ( QEvent * event )

重实现自 QAbstractTransition::eventTest ().

QPainterPath QMouseEventTransition:: hitTestPath () const

Returns the hit test path for this mouse event transition.

另请参阅 setHitTestPath ().

[virtual protected] void QMouseEventTransition:: onTransition ( QEvent * event )

重实现自 QAbstractTransition::onTransition ().

void QMouseEventTransition:: setHitTestPath (const QPainterPath & path )

Sets the hit test path for this mouse event transition to path . If a valid path has been set, the transition will only trigger if the mouse event position ( QMouseEvent::pos ()) is inside the path.
