pyqt6动画不起作用以减小宽度

Question

我在动画上挣扎。它首次提高宽度，但虽然否则陈述就不会减小大小。

def slideLeftMenu(self):
        self.animation=QPropertyAnimation(self.ui.LeftMenuContainer,b'minimumWidth')
        self.animation.setDuration(250)
       
        width=self.ui.LeftMenuContainer.width()
      
    
       
        if width==50:
            
            self.ui.mainBodyContainer.move(100,0)
            self.animation.setStartValue(50)
            self.animation.setEndValue(100)
            self.animation.start()
            
        else:
             self.ui.mainBodyContainer.move(50,0)
             self.animation.setStartValue(100)
             self.animation.setEndValue(50)
             self.animation.setEasingCurve(QtCore.QEasingCurve.Type.InOutQuart)
             self.animation.start()

Answer 1

尝试以下操作：

def slideLeftMenu(self):
    # GET WIDTH
    width = self.ui.LeftMenuContainer.width()
    widthExtended = 50

    # SET MAX WIDTH
    if width == 50:
        widthExtended = 100

    # ANIMATION
    self.animation = QtCore.QPropertyAnimation(self.frame_left_menu, b"minimumWidth")
    self.animation.setDuration(250)
    self.animation.setStartValue(50)
    self.animation.setEndValue(widthExtended)
    self.animation.setEasingCurve(QtCore.QEasingCurve.Type.InOutQuart)
    self.animation.start()
