Accessing UI elements from JS

[ihsan ciftci]

//Export Overlay for Mapviewer
@ExportPackage("Test")
@Test("MapViewer")
public class MapViewer implements ExportOverlay<com.test.MapViewer>(

public MapViewer() { }

);


// Old GWT widget
com.test.MapViewer extends FocusPanel()
{


}


var map = new Test.MapViewer();
//document.body.appendChild(map);

How can I add MapViewer to the body ?
