Lemur button: How to apply the button down effect on own style

Here is the solution that worked for me. I implement the desired behaviour as a style and not as commands to new buttons.

 Attributes attrs = style.getSelector("button", "mystyle");
 // the "moving" of the button
 Command<Button> pressedCommand = new Command<Button>() {
            public void execute( Button source ) {
                if( source.isPressed() ) {
                    source.move(1, -1, 0);
                } else {
                    source.move(-1, 1, 0);
                }
            }
        };

// list of commands + we add the example command
  List<Command<Button>> commandlist = new ArrayList<>();
  commandlist.add(pressedCommand);

// Map of Buttonactions and commands, we add it for "button clicked/unclicked"
 Map<Button.ButtonAction,List<Command<Button>>> commandMap = new HashMap<>();
 commandMap.put(Button.ButtonAction.Down,commandlist);
 commandMap.put(Button.ButtonAction.Up,commandlist);

// finally we add it to the style
attrs.set("buttonCommands",commandMap);
