[news.eclipse.platform.swt] Re: TabItem and Table

["Philippe Geneves" <jphil68x@xxxxxxxx>]

Veronika,

 i've tried to change my code with your answer
 but i can't manage to do what i want

 I want my Tables to appears on the maximum possible size
 even if there's no data in (I load them on a button click)
 I also want them to display their scrollbars if it's needed
 and finally, I won't to fix a size for my TabFolder because
 my application have to be fully resizable
 I manage to do this with this code, but i apply a GridData
 on a FillLayout and it's wrong

 Could you explain me if it's possible and what i'm doing wrong?

thanks
 philippe.
