我怎么能在不冻结主线程的情况下等待 [英] How could I wait without freezing main thread

问题描述

我想制作一个从侧面滚动的表格，但它只是传送

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("SubWindow.ui", self)
        butt = QPushButton()
        self.UploadButton.clicked.connect(self.UploadButtonClicked)

    def UploadButtonClicked(self):
        #self.ui.hide()

        for x in range(25):
            self.LoginText.move(self.LoginText.x(), self.LoginText.y()-10)
            self.UploadButton.move(self.UploadButton.x(), self.UploadButton.y()-10)
            self.PassText.move(self.PassText.x(), self.PassText.y()-10)
        #window.Show()

    def Show(self):
        self.ui.show()
    def Hide(self):
        self.ui.hide()

我启动它，我的程序只是冻结了几秒钟，然后一切都被传送了，但我希望它更流畅

I launch this and my program just freeze for few seconds and then everything teleports up, but I want it to be smoother

推荐答案

我了解您希望小部件平滑移动，在这种情况下，解决方案是使用 QPropertyAnimation:

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)
