忽略Qt中的鼠标和键盘事件 [英] Ignore mouse and keyboard events in Qt

问题描述

在Qt中，我如何才能忽略所有鼠标和键盘事件，然后又停止忽略它们?即:单击一个按钮，忽略子级中的所有事件；再次单击，不要忽略.明白了吗? 我有以下几行，但也许我做错了事:

In Qt, how can I ignore all mouse and keyboard events and later stop ignoring them? That is: click a button, ignore all events in children; click again, not ignore. Is that clear? I have the following lines, but maybe I'm doing something wrong:

setAttribute(Qt::WA_TransparentForMouseEvents);

setFocusPolicy(Qt::NoFocus);

推荐答案

不要使用setFocusPolicy(Qt :: NoFocus);它将事件传播到父级.仅使用setAttribute(Qt :: WA_TransparentForMouseEvents);

Dont use setFocusPolicy(Qt::NoFocus); and it will propagate events to the parent. Use only setAttribute(Qt::WA_TransparentForMouseEvents);
