Is there any way to keep or reconnect debugger after restarting application ?

[dmhk_4ss]

I tried to develop restarting application with this article "How to restart an application by pressing a button?".

But after application restarted, the debugger stopped and I can't reconnect the debugger.
I think I can't keep connecting debugger after "qApp->quit()".

If there is any way to keep debugging after restarted application, please tell me.

Thanks.

I found Attach to Running Application, and I could break C++ code on debugger.
But I can't debug QML code because I can't know QML port for attaching.

So, is there any way to know QML port for restarted application ?

I tried following code
Then app restarted, I tried "Attach to QML port" with QtCreator.
But QtCreator couldn't connect to QML port "34567" for debugging.

void Restarter::makeRestart( QString lib_namme )
{
    process.setProgram(qApp->arguments()[0]);
    process.setNativeArguments({"-qmljsdebugger=port:34567"});
    qint64 pid;
    process.startDetached(&pid);
}

Thanks.
