当他们的孩子被隐藏时调整qt小部件的大小 [英] Resizing qt widgets when their children are hidden

问题描述

当重试子项被隐藏时，我将如何调整小部件的大小，使其看起来像第一张图片?主布局是一个 QVBoxLayout，重试子布局也是一个带有 QVBoxLayout 的小部件.

How would I go about resizing the widget when the retry child is hidden so that it looks as in the first image? The main layout is a QVBoxLayout, the retry child is a widget with a QVBoxLayout as well.

我尝试了以下方法:

• 更新()
• updateGeometry()
• setGeometry(childrenRect())
• layout()->activate()

一旦我将重试小部件设置为隐藏，就在主小部件上.我需要拦截一些事件才能做到这一点吗?

on the main widget as soon as I've set the retry widget to hidden. Do I need to intercept some event to do this?

推荐答案

adjustSize 函数可以做你想做的事.
