Mouse over in Control p5 scrollablelist

Hi, I’m trying to access label names using mouseover in a scrollable list, I have found the following but can’t get it to work - can anyone show me a working example of this?

Thanks

public class MyScrollableList extends ScrollableList {
  // the constructor is required, since there is no constructor in 
  // ScrollableList that allows for implicit calling 
  MyScrollableList (ControlP5 controlp5, String name) {
    super(controlp5, name);
  }
 
  // returns -1 if nothing is selected
  int getHover() {
    return itemHover;
  }
}
 
// ...
 
MyScrollableList myScrollableList = null
myScrollableList = new MyScrollableList (cp5, "myScrollableList");
myScrollableList.setPosition(10, 10)
                .setSize(280, 300)
                .setItemHeight(15);
 
// ...
 
int hoveredItem = myScrollableList .getHover();
if (hoveredItem >= 0) {
  Map<String , Object> item =  myScrollableList getItem(hoveredItem);
  println(item.get("name").toString());
}
