There is plenty of material on the internet on this topic. Please don’t correspond with me directly by email, as that would prevent others from benefiting from the conversation in the future.

It seems to me like you need to learn much more about UDP before you say something like UDP “can’t has log in facility”. That is simply not true.

but it can’t has log in facility…

You would have to instantiate a QStackedWidget in your C++ code, and add different widgets as pages to it. Each widget would probably be a QFrame with the content you want inside it.

This really is a lot easier to do with Designer if you can.

Hi.. tnx Dave!!!!! :)
I read this code, but I’m trying to write it without designer!!!
but I have a big problem
how can I replace this in mainwindow.cxx
void MainWindow::connected()
{
// Flip over to the chat page:
stackedWidget->setCurrentWidget(chatPage);

// And send our username to the chat server.
socket->write(QString(“/me:” + userLineEdit->text() + “\n”).toUtf8());
}
in fact I dont know how open “chatpage” when I did’nt use designer??

Ysabelle,

Your program is very similar to this chat program. You will have to record user input and convert that to text or binary form to be transmitted to the server.

Hey Dave,
thanks for this Program, it helps a lot.

First sry for my bad english, i hope you understand me :)

I have a Question, we have a project named online WhiteBoard.

In it many Clients(User) can paint together on the same White-Board. For that we want to use a Client Server App.

My Question, how can we relize it that the Server gets and send the information of painting, the problem is, in a chat Program you send Strings, but not for painting.

Do you have this in your .pro file:

QT += network
