    Answered: Animating a list to automatically scroll


    Hello everyone. I would like to have a list scroll automatically similar to the credits of a movie. I have a way of doing this, but I am wondering if there is a better way. Right now I am using a delayed task and scrollTo:

    Code:
    this.scrollAnimation = new Ext.util.DelayedTask(function() {
        var yStart = -this.list.scroller.offset.y;
        var newY = yStart + this.scrollDistance;
        this.list.scroller.scrollTo({x:0, y:newY});
        this.scrollAnimation.delay(this.scrollSpeed);
    }, this);
    
    
    Ext.apply(this, {
        items: [this.list],
        listeners: {
            activate: function(){
                this.scrollAnimation.delay(this.scrollSpeed);
            }
        }
    });

  2. The scroller's scrollTo method takes a 2nd argument that is for animate. The 2nd param can be boolean or a number. true to animate, a number for number of milliseconds to animate.
