QUdpSocket bind / connectToHost ?

[mnemonic_fx]

Hi everyone,

I'm asking a basic question about what is the difference, when we use bind / connectToHost on QUdpSocket.

The manual says I could use read & write function after connectToHost, no difference than QTcpSocket.

But when I experimenting with it, on one application I experienced an anomaly,
which is I don't receive readyRead() signal when data arrives at the network.
On another application, I use connectToHost, read & write with no problems.

I'm not sure what is the problem, since I call connectToHost & waitForConnected in both applications.

Additionally, I can use QUdpSocket bind, readDatagram & writeDatagram with no problems

So what causes this, and what are exactly the differences, advantages / disadvantages between these approach in using QUdpSocket ?

Help please

Does this another application also use udp sockets?

Well, all of the udp sockets, uses QUdpSocket.

I'm not sure about your question.

Well at least can anybody explain to me if there is any differences between ordinary use of QUdpSocket (with datagram), compared to using QAbstractSocket ?
