Member Function Documentation
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 for the given object, with the given button and sourceState.
QMouseEventTransition::~QMouseEventTransition()
Destroys this mouse event transition.
bool QMouseEventTransition::eventTest(QEvent * event) [protected]
QPainterPath QMouseEventTransition::hitTestPath() const
Returns the hit test path for this mouse event transition.
See also setHitTestPath().
void QMouseEventTransition::onTransition(QEvent * event) [protected]
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.
See also hitTestPath() and QPainterPath::contains().
