成员函数文档编制

QKeyEventTransition:: QKeyEventTransition ( QState * sourceState = Q_NULLPTR)

Constructs a new key event transition with the given sourceState .

QKeyEventTransition:: QKeyEventTransition ( QObject * object , QEvent::Type type , int key , QState * sourceState = Q_NULLPTR)

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

QKeyEventTransition:: ~QKeyEventTransition ()

Destroys this key event transition.

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

重实现自 QAbstractTransition::eventTest ().

int QKeyEventTransition:: key () const

Returns the key that this key event transition checks for.

注意： Getter 函数对于特性 key .

另请参阅 setKey ().

Qt::KeyboardModifiers QKeyEventTransition:: modifierMask () const

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

注意： Getter 函数对于特性 modifierMask .

另请参阅 setModifierMask ().

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

重实现自 QAbstractTransition::onTransition ().

void QKeyEventTransition:: setKey ( int key )

设置 key that this key event transition will check for.

注意： Setter 函数对于特性 key .

另请参阅 key ().

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

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

注意： Setter 函数对于特性 modifierMask .
