[Qt-interest] QTcpSocket problems

[Donal O'Connor]

Ok So I've changed a little and it works but this method is not ideal

while (m_tcpSocket->waitForReadyRead(1000))

{

 inputData += m_tcpSocket->read(m_tcpSocket->bytesAvailable());

}


I get a TcpSocket time out error from the error signal of the tcp socket
object.


Is there a better way to do this asynchronically rather than using a slot to
wait for ready read signal?



Thanks.


This is not ideal as I don't
