特性文档编制

[bindable] key : int

注意： 此特性支持 QProperty 绑定。

This property holds the key that this key event transition is associated with

[bindable] modifierMask : Qt::KeyboardModifiers

注意： 此特性支持 QProperty 绑定。

This property holds the keyboard modifier mask that this key event transition checks for

成员函数文档编制

QKeyEventTransition:: QKeyEventTransition ( QState * sourceState = nullptr)

Constructs a new key event transition with the given sourceState .

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

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

[virtual noexcept] QKeyEventTransition:: ~QKeyEventTransition ()

Destroys this key event transition.

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

重实现： QEventTransition::eventTest (QEvent *event).

int QKeyEventTransition:: key () const

Returns the key that this key event transition checks for.

注意： Getter function for property 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 function for property modifierMask.

另请参阅 setModifierMask ().

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

重实现： QEventTransition::onTransition (QEvent *event).

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 .

另请参阅 modifierMask ().
