Center TabBar horizontally on the TabWidget

[forrestfsu]

I'm trying to center a tabBar horizontally on a tabWidget.

Example:

instead of
| TAB 1 | TAB 2 | Tab 3 |XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

I desire
XXXXXXXXXXXXXXXXXX| TAB 1 | TAB 2 | Tab 3 |XXXXXXXXXXXXXXXXXX

I should also state that I'm already using a certain style...so I can't simply switch to the Mac-style (which I believe by default aligns tab horizontally centered).

Any pointers are appreciated.
