如果我使用startDetached启动QProcess，是否可以获得完整的插槽 [英] Do I get a finished slot if I start QProcess using startDetached

问题描述

如果使用startDetached（）启动QProcess，是否会收到完成信号？我正在尝试启动一个过程，但是我需要能够在该过程终止时获得一个事件。

Do I get a finished signal if I start a QProcess using startDetached()? I'm trying to start a process, but I need to be able to get an event when the process has terminated.

推荐答案

不，当您使用startDetached时，您会收到信号，因为您没有对象。

No you can't get a signal when you use startDetached because you have no object.

startDetached是静态函数，当您调用它时，该过程将直接启动而无需创建一个QProcess对象。因此，即使有信号，您也无法将其连接到任何东西，因为您没有对象可以连接。

startDetached is a static function and when you call it the process is started directly without creating a QProcess object. Therefore, even if there was a signal you would not be able to connect it to anything since you have no object to connect from.

如果您想要一个信号，则应该创建一个一个QProcess对象，然后对其调用start。然后，您将能够在流程完成时获得完成信号。

If you want a signal you should create a QProcess object and then call start on it. You will then be able to get the finished signal when the process finishes.
