Widget developement

Hi forum,

in codebeamer it is claimed that custom widgets can be developed with Java. The example (demo-widget) that is provided in the Widget Development Documentation worked for me but i have the feeling it is not so easy as it is claimed to develop the widgets.

I also expected that there is a more detailed documentation but i couldn't find anything.

Has anyone experience with widget developement and knows what to do or is it as simple as implementing (almost) everything from scratch?
