Can I set two different look and field on one JFrame?

Answer 1

The look and feel is a (application) global setting. You can't individually combine different ones. How to set the look and feel is described here.

Answer 2

i think Not possible from Java look and feel classes as they are set for whole application like UIManager.setLookAndFeel();

so you have to do it from your own.

Answer 3

A components LAF is determined when the component is created. So theoretically you can do:

a) set LAF
b) create the component
c) reset the LAF to the default.

You may or may not encounter problems so use at your own risk.
