what the syntax to do that??There's no "syntax" involved. Instead you have to read up on and study the various layout managers. You could for instance use a BoxLayout to stack information on top of each other, and put your checkboxes in their own panel that uses flowlayout. There's many many ways to arrange this, and the best is the one that works for you. Start here .
