Python-更新GUI，因此它始终使用更新后的列表

• 问答

我有一个项目，其中一个框架中有多个“小部件”。我将窗口小部件列表传递到名为GUI的类上，该类显示所有这些“窗口小部件”。我的相框上有一个按钮，需要从列表中删除其中一个小部件。是的。但是小部件本身不会从框架中消失。

因此请澄清

GUI类具有对象[Object,Object,Object]的列表。因此，它现在显示4个Widget对象。当我按下删除按钮时，新列表看起来像[Object,Object]，但是GUI类中的列表仍然是[Object,Object]。如何使GUI始终使用列表的最新版本？

要澄清的代码

qqcoboo 回答：Python-更新GUI，因此它始终使用更新后的列表

您可以尝试类似

def removeWidget(self):
    widget = self.widgets.pop()
    widget.widgetFrame.pack_forget()
    print(self.widgets)
python-3.xtkinter
