[PyQt] Help with QStateMachine and animations

[Demetrius Cassidy]

Actually I found out you can add this to a QAbstractTransition, but it does
not make a difference. It seems that the animation which moves widgets
off-screen does not play. I only see the widgets moving on-screen.

slightly modified code:

def _createAnimations(self):
        self._stateProceeding = QState()
        self._stateReleased = QState()
        self._stateMachine = QStateMachine()
        
        self._rtpAnimation = QPropertyAnimation(self.pageRTP, "pos")
        self._queueAnimation = QPropertyAnimation(self.pageQueue, "pos")
        self._rtpAnimation.setEasingCurve(QtCore.QEasingCurve.InOutCubic)
        self._queueAnimation.setEasingCurve(QtCore.QEasingCurve.InOutCubic) 
        
        self._rtpAnimation.setDuration(600)
        self._queueAnimation.setDuration(self._rtpAnimation.duration())
        
        transition = self._stateProceeding.addTransition(self.callReleased,
self._stateReleased)
        transition.addAnimation(self._queueAnimation) #move off-screen
        transition.addAnimation(self._rtpAnimation)     #move on-screen
(works)
        
        transition = self._stateReleased.addTransition(self.callProceeding,
self._stateProceeding)
        transition.addAnimation(self._rtpAnimation)     #move off-screen
        transition.addAnimation(self._queueAnimation) #move on-screen
(works)

                
        #start at 0,0 and move offscreen towards the right
        self._stateProceeding.assignProperty(self.pageQueue, "pos",
QPoint(self.pageQueue.width(), self.pageQueue.y()))
        
        #set QStackedWidget index
        self._stateProceeding.assignProperty(self.stackedWidget,
"currentIndex", self.stackedWidget.indexOf(self.pageRTP))
        
        #start offscreen from the left and move towards center
        self._stateProceeding.assignProperty(self.pageRTP, "pos",
QPoint(0,0))
        

        #start offscreen from the right and move towards center
        self._stateReleased.assignProperty(self.pageRTP, "pos",
QPoint(-self.pageRTP.width(), self.pageRTP.y()))
        
        #set QStackedWidget index
        self._stateReleased.assignProperty(self.stackedWidget,
"currentIndex", self.stackedWidget.indexOf(self.pageQueue))
        
        #start at 0,0 and move offscreen towards the left
        self._stateReleased.assignProperty(self.pageQueue, "pos",
QPoint(0,0))
        

        self._stateMachine.addState(self._stateReleased)
        self._stateMachine.addState(self._stateProceeding)
       
self._stateMachine.setGlobalRestorePolicy(QStateMachine.DontRestoreProperties)
        self._stateMachine.setInitialState(self._stateReleased)
        self._stateMachine.start()
