# QKeyEventTransition Class Reference ## [[QtGui](index.htm) module] 該QKeyEventTransition類提供了關鍵事件的轉變。[More...](#details) 繼承[QEventTransition](qeventtransition.html)。 ### Methods * `__init__ (self, QState?sourceState?=?None)` * `__init__ (self, QObject?object, QEvent.Type?type, int?key, QState?sourceState?=?None)` * `bool eventTest (self, QEvent?event)` * `int key (self)` * `Qt.KeyboardModifiers modifierMask (self)` * `onTransition (self, QEvent?event)` * `setKey (self, int?key)` * `setModifierMask (self, Qt.KeyboardModifiers?modifiers)` * * * ## Detailed Description 該QKeyEventTransition類提供了關鍵事件的轉變。 QKeyEventTransition是一部分[The State Machine Framework](index.htm)。 * * * ## Method Documentation ``` QKeyEventTransition.__init__ (self, QState?sourceState?=?None) ``` 該_sourceState_的說法，如果不是沒有，原因_self_通過Qt的，而不是PyQt的擁有。 構造具有給定一個新的關鍵事件轉變_sourceState_。 ``` QKeyEventTransition.__init__ (self, QObject?object, QEvent.Type?type, int?key, QState?sourceState?=?None) ``` 該_sourceState_的說法，如果不是沒有，原因_self_通過Qt的，而不是PyQt的擁有。 構造對給定事件的一個新的關鍵事件轉變_type_對于給定的_object_用給定的_key_和_sourceState_。 ``` bool QKeyEventTransition.eventTest (self, QEvent?event) ``` 從重新實現[QAbstractTransition.eventTest](qabstracttransition.html#eventTest)（ ） 。 ``` int QKeyEventTransition.key (self) ``` ``` Qt.KeyboardModifiers QKeyEventTransition.modifierMask (self) ``` [ ``` QKeyEventTransition.onTransition (self, QEvent?event) ``` ](index.htm) [從重新實現](index.htm)[QAbstractTransition.onTransition](qabstracttransition.html#onTransition)（ ） 。 ``` QKeyEventTransition.setKey (self, int?key) ``` ``` QKeyEventTransition.setModifierMask (self, Qt.KeyboardModifiers?modifiers) ```
