Skinning Tutorial

You want to create skins for yourself or to share them with the users community? It's very simple! Skinnable plug-ins are delivered with several skins inside. You can start with one of them and modify it to do your own.

Read the KUIML language user manual (download as chm), download the tutorial samples and you are ready to go!

KUIML is a simple yet powerful programming language: you do not need to be a programmer or a graphics designer to create a skin that suits your needs. Get started and post your skin when it's ready! Join the designers who have already uploaded skins for our Download Skins page.
