ScrollBar in LWUIT

How can I edit the style of the lists´ scrollbar?

I want to modify its wid开发者_C百科th, mainly.

To change his colors I use the UIID ScrollThumb, is this correct?

Thanks

@Shai Almog shows me how to edit the ScrollBar.
Using the UIIDs "Scroll" and "ScrollThumb", I can customize my apps´ scroll. Modifying padding/background I can control the width.

There are so many examples in the LWUIT svn.
