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 ) [virtual protected]

Reimplemented from QAbstractTransition::eventTest().

QPainterPath QMouseEventTransition::hitTestPath () const

Returns the hit test path for this mouse event transition.

See also setHitTestPath().

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

Reimplemented from 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.

See also hitTestPath() and QPainterPath::contains().
