pyqt:如何删除小部件? [英] pyqt: how to remove a widget?

问题描述

我有一个 QGroupBox 小部件，里面有我想删除的孩子.我怎么做?我在 文档.我只能看到如何从布局中删除内容，但这显然并没有从实际的小部件中删除它.

I have a QGroupBox widget with children in it that I want to remove. How do I do that? I can't find any removeWidget, removeChild, removeItem, or anything similar in the docs. I can only see how to remove things from a layout, but that, apparently, doesn't remove it from the actual widget.

推荐答案

嗯，这有效:在我想删除的小部件上，调用 widget.setParent(None).我喜欢向布局添加小部件向容器添加小部件的方式，但从布局中删除并不......有趣的东西.

Well, this works: on the widget i want to remove, call widget.setParent(None). I like how adding to a layout adds a widget to the container, but removing from a layout doesn't... fun stuff.
