In your application you must add in your public repository the following folder:

• rialtoEngine
• * images
• * style

Put in the image folder your specific images and in the style folder the css you want to use. The css must be a copy of the original defaultSkin.css where you put your own style.

This link must be after the rialtoGWT inherits.

<module>
        <!-- Inherit the core Web Toolkit stuff.                  -->
	<inherits name='com.google.gwt.user.User'/>
	<inherits name="fr.improve.rialto.gwt.core.Rialto"/>
	<stylesheet src="rialtoEngine/style/NewRialtoSkin.css"/>
	<!-- Load default skin stylesheet -->
	<!-- Specify the app entry point class.                   -->
	<entry-point class='fr.improve.gwt.client.TestGWT'/>
</module>

After you must register and activate this css add in the moduleLoad fonction of your entry-point.

public void onModuleLoad() {
	SkinRegistry.registerSkin(null, "NewRialtoSkin");
	SkinRegistry.activateSkin("NewRialtoSkin");
