主动宣告
setProcessState(QProcess::NotRunning)
或者在堆上new一个QProcess。

I had exactly the same problem, and could not solve it in a clean way. I have found 2 options:
- Hacky way: Subclass
QProcess
and callsetProcessState(QProcess::NotRunning);
after starting the process. This will prevent the destructor to terminate the process. But it relies on an implementation detail ofQProcess
-
Create a memory leak: Dynamically create the
QProcess
on the heap, but never delete it, and thus never invoke its destructor
{ QProcess *process = new QProcess; process->start("taskkill", QStringList() << "/f" << "/im" << "My Service.exe"); }
