Examples of com.sun.dtv.lwuit.Component

com.sun.dtv.lwuit.Component
Base class for all the widgets in the toolkit using the composite pattern in a similar way to the AWT Container/Component relationship. All components are potentially animated (need to be registered in {@link Display}). @author Chen FishbeinFormato JAVA DTV 1.1 por @author Leonardo Baptista
