Hello I am learning Swingx, but I haven´t found good codes or information.
Can you give me a link or tutorial or something?
But the most important thing would be source code

Theres currently a project in progress called JDNC (Java Desktop Network Connectivity). I believe SwingX is a part of that project..
Check out community.java.net - JavaDesktop for more information.
Hans Muller talked at JavaPolis in April and it seemed that the project is still under heavy development..
