我希望我创建的 CustomLabels 和 CustomToggleButtons 根据不同的窗口大小来改变它们的大小。所以这就是我所做的。
lbl = CustomLabel（文本=文本，宽度=self.grid_layout.width，>高度=self.grid_layout.height*.5）
btn = CustomToggleButton(group=text, text=config_type[i], width=40 + >len(config_type[i]) * 20, height=self.grid_layout.height * .5)
我所做的是将上述小部件的高度和宽度设置为与包含它们的 GridLayout 成比例。GridLayout 的大小是相对于 MainScreen 的。因此，如果我更改 Window 大小，GridLayout 将紧随其后，然后是小部件。
但是，它没有用。每当我更改 Window 大小时，CustomLabels 和 ToggleButtons 的大小都会保持不变。将不胜感激一些帮助，谢谢！
这是完整的代码：
