Question

当MainWindow失去焦点时，我试图减小App的高度，但是下面的代码没有发生这种情况。

class MyApp(QMainWindow):
    def __init__(self):
        super(MyApp, self).__init__()
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.installEventFilter(self)
        time_frame_values = [i/30 for i in range(30)]
        self.timeFrame = map(lambda x: x**0.5, time_frame_values)


    def eventFilter(self, widget, event):
        if event.type() == QEvent.FocusOut:
            self.on_focus_out()
            print("Focus Out!")
        return False

    def on_focus_out(self):
        print("Focus Out!!")
        for i in reversed(self.timeFrame):
            self.move(QPoint(ScreenSizeObject.width()-self.width()-10, ScreenSizeObject.height()-self.original_height-(i*300)))
            self.ui.textDisplay.resize(QSize(self.ui.textDisplay.width(), self.ui.textDisplay.height() + (i * 15)))

            time.sleep(0.01)

此处self.on_focus_out()将产生过渡效果。

期望：当我单击主窗口中的任意位置时，我希望self.on_focus_out()运行。

可靠性：没有过渡效果，甚至print('Focus Out!')都不打印字符。

感谢您的努力！

对于所需的行为，将QEvent.FocusOut更改为QEvent.WindowDeactivate，问题就解决了！

重写正确的代码，

class MyApp(QMainWindow):
    def __init__(self):
        super(MyApp, self).__init__()
        self.ui = Ui_MainWindow()
        self.ui.setupUi(self)
        self.installEventFilter(self)
        time_frame_values = [i/30 for i in range(30)]
        self.timeFrame = map(lambda x: x**0.5, time_frame_values)


    def eventFilter(self, widget, event):
        if event.type() == QEvent.WindowDeactivate:
            self.on_focus_out()
            print("Focus Out!")
        return False

    def on_focus_out(self):
        print("Focus Out!!")
        for i in reversed(self.timeFrame):
            self.move(QPoint(ScreenSizeObject.width()-self.width()-10, ScreenSizeObject.height()-self.original_height-(i*300)))
            self.ui.textDisplay.resize(QSize(self.ui.textDisplay.width(), self.ui.textDisplay.height() + (i * 15)))

            time.sleep(0.01)
