QSocketNotifier can not enable from an other thread.

I did not understanda at all.

Both thread class lives in main thread. but when I connect both thread with direct connection than, as I know , slot will invoked in the caller thread event loop. But , it does not have permission to use socket object , created in the second thread.

Try to print QThread::currentThread() in the slot and you'll see the problem. I'd recommend reading the Multithreading presentation by Bradley T. Hughes from TT DevDays 2007. Especially the chapter starting from page 32 is important to understand.
