Look and Feel

The look and feel can be specified on a per-OS basis. For instance you can use the native look and feels on Win32 and OS X but use a third-party one on Unix-like platforms. To do that, you have to add some <laf> child elements to the <guiprefs> element.:


  • Kunststoff: kunststoff
  • Liquid: liquid
  • Metouia: metouia
  • JGoodies Looks: looks
  • Substance: substance
  • Windows: windows
  • Aqua: aqua
  • Metal: metal

If you don't specify a look and feel for a particular operating system, then the default native one will be used: Windows on Windows, Aqua on Mac OS X and Metal on the Unix-like variants.
