Examples of com.google.gwt.user.client.Timer

com.google.gwt.user.client.Timer
A simplified, browser-safe timer class. This class serves the same purpose as java.util.Timer, but is simplified because of the single-threaded environment.
To schedule a timer, simply create a subclass of it (overriding {@link #run}) and call {@link #schedule} or {@link #scheduleRepeating}.

NOTE: If you are using a timer to schedule a UI animation, use {@link com.google.gwt.animation.client.AnimationScheduler} instead. Thebrowser can optimize your animation for maximum performance.
