如何在不同的Qt线程中调用GUI元素? [英] How to call GUI elements in different Qt threads?

问题描述

我有一个应用程序，其中一个线程(不是主线程)需要访问GUI的元素(发送单击动作，显示消息框等).我在python和Qt中工作，也知道在非主线程中是不可能的. 有办法吗?我的意思是将要在线程中执行的操作发送到主线程.

I have an application in which a thread (not main thread) needs access to the GUI's elements (send a click action, show a message box, etc). I am working in python and Qt and also know that it is not possible when in not main thread. Is there a way to do it? I mean to send the action that I want to do in the thread to the main thread.
