SWT - How to change the order of existing TabItems in a TabFolder

How do I change the order of existing TabItems in a TabFolder? Sorry for not being able to post more, but I just have completely no clue. TabItems don't have a z-Index, moveAbove() and moveBelow() of the containe开发者_StackOverflow中文版d composites don't work, I have the feeling to have tried everything.

Regards, Daniel

On our project, we had to do that. We disposed the old tab and created a new one on the correct position.
