Resize Jpanel and JtabbedPane

Question

Hi All,
i implement a resize process on jpanel that include JtabbedPane inside.
it working fine except one thing.
when i resize my panel it work fine, until some point it start to shrink and get smaller.
i think it getting shrink because im getting to the end of my dialog.
i want to avoid this beheviour and let the tabbedpanel extend as much as possible:
this is my code:

hey gabi,
i tried your code and it works just fine.... there is no shrinking or any resizing problem?! i don't know... maybe i just don't get it? so maybe u could describe your problem a little more?!
:)
