    Default Starting QProcess from QThread

    I was using QThreads in Qt where my need is to launch a command-line executable from within a Qt thread and run the same within the thread's context. I have used the below mentioned code for the same which seems to be running fine. However, I wanted to know if this kind of usage is permitted since we are launching a QProcess from within a QThread.

    Qt Code:
    1. void Help_Menu_Thread::run()
    2. {
    3. Insert_Log("INFO::Help file referred by Admin");
    4. QProcess HelpStart;
    5. HelpStart.execute("c:\\windows\\hh.exe LPRS_help.chm");
    6. HelpStart.close();
    7. }

    Awaiting your response.

    Regards,
    Sandeep

    I would just use QProcess::startDetached and not use a thread at all for this kind of stuff.

    Default Re: Starting QProcess from QThread

    Since, Thread is a lightweight and process is the heavyweight, So it is unnecessary to define a heavyweight process under lightweight. I am not confirmed about that, but that what my perception says....
