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!");
}
});
