The designer just changes it on the fly so you can see what it looks like. You
need to right a line of code to force it in your code, if that is what you want.
(I think that swing kind of expects you to use the default look & feel for the
platform you are running on).
To force it to a particular look&feel you need to  add a line that executes
before any UI is created (a static initializer works well):
javax.swing.UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());

where the parameter is the look&feel that you wish to use. To change it
on-the-fly
use SwingUtilities.updateComponentTreeUI(Component parent_of_your_world); after
you have set the look and feel as above.
