Feel free to use anywere .. Hope that it might be useful for someone else too... <br /> <br /><code> <br />public interface MouseWheelListener { <br /> <br /> public void onMouseWheelUp(int intensity); <br /> <br /> public void onMouseWheelDown(int intensity); <br /> <br />} <br /> <br />public class MouseWheel { <br /> <br /> private MouseWheel(Element e, MouseWheelListener listener) { <br /> attachMouseWheelListener(e, listener); <br /> } <br /> <br /> /** <br /> * Sets a MouseWheelListener to a given Element <br /> */ <br /> public static void setMouseWheelListener(Element e, MouseWheelListener listener) { <br /> new MouseWheel(e, listener); <br /> } <br /> <br /> <br /> /** <br /> * This method is used by FF <br /> * @param event <br /> */ <br /> private static native void dispatchMouseWheelEvent(JavaScriptObject event) /*-{ <br /> <br /> @br.com.example.client.util.MouseWheel::dispatchMouseWheelEvent(Lcom/google/gwt/core/client/JavaScriptObject;Lbr/com/example/client/util/MouseWheelListener;)(event, this.__mousewheellistener); <br /> <br /> }-*/; <br /> <br /> /** <br /> * This method is used by IE and FF <br /> * Part of this method was retrieved from http://adomas.org/notes/mouse-wheel.html <br /> * <br /> * @param event <br /> * @param listener <br /> */ <br /> private static native void dispatchMouseWheelEvent(JavaScriptObject event, MouseWheelListener listener) /*-{ <br /> <br /> if (!event) event = $wnd.event; // For IE <br /> <br /> var delta = 0; <br /> if (event.wheelDelta) // IE case, delta is multiple of 120 <br /> delta = event.wheelDelta / 120; <br /> else if (event.detail ) // Mozilla case <br /> delta = -event.detail / 3; // different sign and multiple of 3 <br /> <br /> if ( delta > 0 ) { <br /> listener.@br.com.example.client.util.MouseWheelListener::onMouseWheelUp(I)(delta); <br /> } else { <br /> listener.@br.com.example.client.util.MouseWheelListener::onMouseWheelDown(I)(-delta); <br /> } <br /> <br /> //taken from http://adomas.org/javascript-mouse-wheel/test2.html <br /> if (event.preventDefault) <br /> event.preventDefault(); <br /> event.returnValue = false; <br /> <br /> }-*/; <br /> <br /> <br /> private native void attachMouseWheelListener(Element e, MouseWheelListener listener) /*-{ <br /> <br /> e.__mousewheellistener = listener; <br /> <br /> // for FF <br /> if (e.addEventListener) { <br /> e.addEventListener('DOMMouseScroll', @br.com.example.client.util.MouseWheel::dispatchMouseWheelEvent(Lcom/google/gwt/core/client/JavaScriptObject;), false); <br /> return; <br /> } <br /> <br /> // for IE <br /> e.onmousewheel = function(event) { <br /> @br.com.example.client.util.MouseWheel::dispatchMouseWheelEvent (Lcom/google/gwt/core/client/JavaScriptObject;Lbr/com/example/client/util/MouseWheelListener;)(event, this.__mousewheellistener); <br /> } <br /> <br /> }-*/; <br /> <br />} <br /></code> <br /> <br /> <br />And here is how to use it: <br /> <br /><code> <br /> <br /> MouseWheel.setMouseWheelListener(RootPanel.get("slot2").getElement(), new MouseWheelListener() { <br /> <br /> public void onMouseWheelUp(int intensity) { <br /> Window.alert("up..
