Re: Adding Event Handlers on the body element...

Similarly you should probably also check the type. and you could
emulate the normal handler style of the rest of the GWT architecture.

Event.addNativePreviewHandler(new NativePreviewHandler()
{
@Override
public void onPreviewNativeEvent(NativePreviewEvent event)
{
NativeEvent ne = event.getNativeEvent();
if
(KeyDownEvent.getType().getName().equals(ne.getType()))
System.out.println("Yipeee!");
}
});
