Scroll Pane Question

[pavan vadavalli]

Hi ,

I would like to understand the usage of ScrollPane. Tutorial has just 
ImageView example
Here i did a small test to add several Push Buttons to Boxpane added to 
a Scroll Pane, But i dont see any Scroll Bar coming up.

Attached is the bxml test for Scroll pane.
Can someone please help.
Thanks and Regards,
Pavan
