[Qt-interest] need some QThreading help

Hello everyone......I'm building a multithreaded client-server app, and I
seem not to be getting through with my QThread subclass,
the server's main thread listens for incoming conns. and spawns a new
QThread subclass everytime one arrives...........
however, run-time complains that it can't create children in a thread
different from the parent  thread (i thinks its talking about my QThread
subclass "ServerThread"

i.e in inComingConnection()
{
I created a ServerThread *ptr on stack.............
I also created a QTcpSocket *ptr too...............
connect(readyRead) here to a slot in ServerThread..............
and somehow find a way to move them both out to the new
thread...............
the ServerThread constr. takes a QTcpSocket *ptr as arg, so I pass the one I
allocated............
the ServerThread has a public func that takes a ServerThread *ptr so I
passed the ServerThread I allocated on the Stack........
finally I connected a SIGNAL in serverThread that's emitted in run(),
(before exec() in run() ) that passes the (threadID *, QTcpSocket *ptr,
ServerThread *ptr) to a slot in my main thread.........
(call thread->start())................................
from the slot in my main thread I moved the socket and thread to the given
thread to be both there before exec is reached..............
(they got there after exec() )...........

}

all to no avail................
pls help
( I did this to circumvent the problem of not being able to create children
in a different thread..............
 however the new problem that emerged is "...............

QObject::moveToThread: Current thread (0x8277490) is not the object's thread
(0x83dd408).

Cannot move to target thread (0x83dd408)
