这是一个可调整大小的窗口的示例代码，它在调整窗口大小时会移动并拉伸窗口小部件.这个想法是保持小部件的坐标和大小彼此相对.

here is an example code of a resizable window it moves and stretches widgets as you resize the window. The idea is to keep widget coordinates and sizes relative to each other.

所以我必须做一个class Ui_MainWindow并将其设置为我的窗口类ui2.setupUi(self)，还要声明resized = pyqtSignal()，我将用它来运行readjust函数，该函数可以像这样重置小部件的大小和坐标self.resized.connect(self.readjust).

so i had to make a class Ui_MainWindow and set it for my window class ui2.setupUi(self) and also declare the resized = pyqtSignal() which i'd be using to run the readjust function which resets size and coordinates of the widgets like so self.resized.connect(self.readjust).

我希望这会有所帮助！
