LCDUIEvent

public class LCDUIEvent extends com.sun.midp.events.Event
An subclass for "synthetic" LCDUI events. These events are generated by LCDUI for its own purposes, and they include events whose type codes are SCREEN_CHANGE_EVENT, CALL_SERIALLY_EVENT, INVALIDATE_EVENT and ITEM_EVENT. Events generated by the system, such as keystrokes and commands, are not considered to be synthetic events because they represent some actual user action. TBD: Class need to be PUIBLIC only if LCDUIEvent will be needed outside of the package
