Hi,
I think that the problem is that TabLayoutPanel has to be used woth
LayoutPanels
(http://www.gwtproject.org/doc/latest/DevGuideUiPanels.html#LayoutPanels)
whereas i told you to use RootPanel (that is not a LayoutPanel).
Change
RootPanel.get.add(helloWorld);
with
RootLayoutPanel.get.add(helloWorld);
and
public class Hello extends Composite {
with
public class Hello extends ResizeComposite {
(
http://www.gwtproject.org/javadoc/latest/com/google/gwt/user/client/ui/ResizeComposite.html
)
and should work.
Cannot try your code so my respoonse may be incomplete.
Ciao,
Alberto.
