What effects libraries are available for GWT for commercial use?

Question

I\'m looking for an effects library that I can drop in to my existing GWT app really, really easily. I want to add the library to my build path and then start writing thing

Answer 1

I needed just fade in and fade out effects. So I didn't use a library. This is the code doing these effects.

    private void fadeIn(final Element el) {
    final int size = 11;
    Timer timer = new Timer() {
        private int counter = 0;
        @Override
        public void run() {                     
            if (counter == size) {
                cancel();
                return;
            }
            double opacity = (double) (counter) /  10;                      
            el.getStyle().setOpacity(opacity);                      
            counter++;      
        }
    };
    timer.scheduleRepeating(100);   


}

private void fadeOut(final Element el) {
    final int size = 11;
    Timer timer = new Timer() {
        private int counter = 0;
        @Override
        public void run() {                     
            if (counter == size) {
                cancel();
                return;
            }
            double opacity = (double) (10 - counter) /  10;                     
            el.getStyle().setOpacity(opacity);                      
            counter++;      
        }
    };
    timer.scheduleRepeating(100);       
}
