Scrolling tab bars

Hi,

Is it possible to fix the size of a tab bar item, but for the the tab bar itself to scroll left and right?

For example

+-----------------------+
|      |      |      |  |
|  t1  |  t2  |  t3  | t|
+-----------------------+

the tab items are the same size, but tab 4 is only part on screen, so the bar scrolls when required.

Thanks

Paul
