public class MyTreeSkin extends TerraTreeViewSkin {
        public MyTreeSkin () {
          super();
        }
                
        public boolean mouseClick(Component component, Mouse.Button button,
int x, int y, int count) {
                System.out.println("SKIN comp:"+component.toString());
                return super.mouseClick(component, button, x, y, count);
        }
}


public class MyTree extends TreeView {
        public MyTree() {
                super();
                installSkin(TreeView.class);
        }
}

in startup(display,...) {
this.display = display;
Theme.getTheme().set( TreeView.class, MyTreeSkin.class);
.....
}

I'm getting an exception:

java.lang.IllegalArgumentException: java.lang.InstantiationException:

And:
public void create_hosts_tree() {
my_tree = new MyTree();
...
}



thanks
