+## Events types constants
+
+There is a long list of available events for some objects, and the developer may not know what events are available for the object they are using. The [EventType](https://github.com/gwidgets/gwty-leaflet/blob/master/src/main/java/com/gwidgets/api/leaflet/events/EventTypes.java) class contains a list of subclasses which contains the available events types constants. The event type can be accessed in static a way like: EventType.{object name}.{event type constant}. For example, to register the loading event on a TileLayer : 
+
+```java
+tile.on(EventTypes.TileLayer.LOADING, new Function(){
+                        @Override
+                        public JavaScriptObject call(JavaScriptObject event) {
+
+                               //cast raw event object
+                               TileEvent tileEvent = event.cast();
+                               //Do something
