成員函數文檔編製

QMouseEventTransition:: QMouseEventTransition ( QState * sourceState = Q_NULLPTR)

Constructs a new mouse event transition with the given sourceState .

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

Constructs a new mouse event transition for events of the given type 為給定 object ，采用給定 button and sourceState .

QMouseEventTransition:: ~QMouseEventTransition ()

Destroys this mouse event transition.

Qt::MouseButton QMouseEventTransition:: button () const

Returns the button that this mouse event transition checks for.

注意： getter 函數對於特性 button .

另請參閱 setButton ().

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

重實現自 QAbstractTransition::eventTest ().

QPainterPath QMouseEventTransition:: hitTestPath () const

Returns the hit test path for this mouse event transition.

另請參閱 setHitTestPath ().

Qt::KeyboardModifiers QMouseEventTransition:: modifierMask () const

Returns the keyboard modifier mask that this mouse event transition checks for.

注意： getter 函數對於特性 modifierMask .

另請參閱 setModifierMask ().

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

重實現自 QAbstractTransition::onTransition ().

void QMouseEventTransition:: setButton ( Qt::MouseButton button )

設置 button that this mouse event transition will check for.

注意： setter 函數對於特性 button .

另請參閱 button ().

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.

另請參閱 hitTestPath () 和 QPainterPath::contains ().

void QMouseEventTransition:: setModifierMask ( Qt::KeyboardModifiers modifierMask )

Sets the keyboard modifier mask that this mouse event transition will check for to modifierMask .

注意： setter 函數對於特性 modifierMask .

另請參閱 modifierMask ().
