QThread: Destroyed while thread is still running

[Shuchi Agrawal]

I guess you didn't try my solution...

yes i do tried solution given by you, but the entire program hangs on clicking "stop thread" button.

void MainWindowImpl::Stop_Thread()
{	flag_stop = true;
	freeBytes.release();  //QSemaphore freeBytes;
	usedBytes.release();  //QSemaphore usedBytes;
	producer->wait();  
	consumer->wait();
}

void MainWindowImpl::Stop_Thread()
{	flag_stop = true;
	freeBytes.release();  //QSemaphore freeBytes;
	usedBytes.release();  //QSemaphore usedBytes;
	producer->wait();  
	consumer->wait();
}
