NetBeans LookAndFeel
Change look-and-feel of NetBeans by editing netbeans.conf located at:
<install dir>\etc\netbeans.conf
Find netbeans_default_options and add the following option to the line:
–laf javax.swing.plaf.metal.MetalLookAndFeel
This will change it to the nice Metal cross-plattform look-and-feel.
