- <h2><span>Wt Chat client</span></h2>
- <p>This is a multi-user chat client and server.</p>
- <p>To keep the example simple, server and clients all run in the same
- process. Still, because all I/O in Wt is asynchronous even when using
- "server push" which requires an open connection with each client at
- all times, clients do not tie up threads, and as such the application
- could easily support thousands of simultaneous users as well.</p>
- <p>The client is contained in a widget (SimpleChatWidget), and can be
- instantiated as many times as you like, even in the same
- application.<br />
- Because of the widget abstraction, it is straight forward to include a
- chat client in your own application, by linking both the client and
- server classes into your application.</p>
- </message>
- <message id="details">
- <p>The implementation uses server-initiated updates, a feature that is
- not much different from regular client-server communication in Wt, and
- allows updating a session from outside its regular event loop. When a
- message is received, the user interface (i.e. widget tree) not only of
- the current session, but also of all other sessions is updated and
- "pushed" to these clients simultanously.</p>
