Do I get a finished slot if I start QProcess using startDetached

by

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

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.

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.
