Design

Nchat is a multi-threaded application. Each protocol (i.e. Telegram) should implement a thread processing RequestMessage it received through its SendRequest() method.

The protocol passes information to the main application by passing ServiceMessage to its message handler, which is processed in a worker thread.

The interface each protocol need to implement is defined in the abstract class Protocol and protocol.h contains definitions of all messages passed between main application and the protocol.

The core application logic is implemented in uimodel.cpp and the display is handled by ui*view.cpp files.
