Then I found this explanation but not want to do it static...

Thanks you!. 
It's a very interesting way, but then dismiss it because restrict me in the construction of graphical user interface.. Or to make rich user interfaces, would have to write many new controls.. I think not worth it .. :(


Attach a "sketch" of what I intend to do..

Lack entire deployment serial port, and simulated events using a timer to Raise events. To continue the development, momentarily, I do dependency injection (See FTest.class:12 and DigitalSwitch.class:39).

This is exactly what I wanted to avoid, but at the moment allow me to continue.. Of course, for the user, it is a single line of code, but want to do it editable graphically..

Matias
