How Could I Wait Without Freezing Main Thread

I want to make a form rolling out from side, but it just teleports class SubWindow(QMainWindow): def __init__(self): QMainWindow.__init__(self) self.ui = loadUi

Solution 1:

I understand that you want the widget to move smoothly, in that case the solution is to use QPropertyAnimation:

def UploadButtonClicked(self):
    animation_group = QParallelAnimationGroup(self)
    for w in (self.LoginText, self.UploadButton, self.PassText):
        start_pos = w.pos()
        end_pos = w.pos() + QPoint(0, -10)
        animation = QPropertyAnimation(
            self,
            propertyName=b"pos",
            targetObject=w,
            startValue=start_pos,
            endValue=end_pos,
            duration=1000,
        )
        animation_group.addAnimation(animation)
    animation_group.start(QParallelAnimationGroup.DeleteWhenStopped)
