Hi Deepak,
The most you should need to do is the following:
AbsolutePanel absPanel = new AbsolutePanel();
for(int i = 0; i < 10; i++){
SimplePanel simp = new SimplePanel();
simp.setHeight("100px");
simp.setWidth("500px");
simp.getElement().getStyle().setBackgroundColor("green");
absPanel.add(simp);
}
MyScrollPanel scrollPanel = new MyScrollPanel();
scrollPanel.setHeight("500px");
scrollPanel.setWidth("100px");
scrollPanel.add(absPanel);
RootPanel.get().add(scrollPanel);
If the above code does not give you a green scrollable box then you should
recheck your code. With the code I sent you and the above code, you should
have a custom scroll bar (not native). You should at the very least have
the above code working. Hope this helps. Let me know.
