java zkoss EventListener how to get variables of event

I debug from EventListener in InteliJ IDEA and get some variables like _val, _oldVal, _selbk, _start, _name ... But I don't know how to get those variables. Here is my code:

myDoublebox.addEventListener(Events.ON_CHANGE, new org.zkoss.zk.ui.event.EventListener() {
    @Override
    public void onEvent(Event event) throws Exception {
        //just for debug
        System.out.println(event);
    }
});

You need to write something like this 

    yDoublebox.addEventListener(Events.ON_CHANGE, new org.zkoss.zk.ui.event.EventListener() {
        @Override
        public void onEvent(Event event) throws Exception {
            Map<String, Object> data = (Map<String, Object>)event.getData();
            String _val = (String) data.get("_val");
            Double _oldVal = (Double) data.get("_oldVal");
            Double _selbk = (Double) data.get("_selbk");
    }
});

You can access the data of the object Event using the getter methods. Like:

  • event.getData() returns the value of the event (the object set as the value of the event)
  • event.getName() returns what kind of event it is

You can get all the informations here: : https://www.zkoss.org/javadoc/8.0.0/zk/org/zkoss/zk/ui/event/Event.html
