GUI

How to read class ClientBackgroundManager, which is main class for GUI using Qt

This class is badly written, actual version (one class) is different from my previous plans to write one class for graphic and one background class for main code...

Code starting with /test/ is solution to my problem with dynamical generation of buttons for client list, which doesn't work. This code is currently fixed and work without problems with signals and threads, but I should rewrite it later.

To understand GUI, many nice examples are part of Qt documentation.
