二、QThread推荐实现方式 - moveToThread 在确定使用QThread后,发现QThread - Qt for Python 官方文档写得很一般,甚至给的example都不堪入目。 我在Stack Overflow的文章找到Pyqt5注释详细的实现,Pyside6的实现也就很类似,也很可以帮助理解QThread的建立过程,以及在Python多线程之threading.Thread()基本使用和QT信...

1. 不使用事件循环。这是官方的 Manual 、example 以及相关书籍中都介绍的一种的方法。 a. 子类化 QThread b. 重载 run 函数,run函数内有一个 while 或 for 的死循环 c. 设置一个标记为来控制死循环的退出。 2. 使用事件循环。(博客you are-doing-it-wrong批驳的就是这种情况下的 一种用法。) ...
