PR3: How can I access/set the class of the sliderfield's thumb?

[minorbug]

I need to change the thumb image depending on the value.

In PR2 I was able to do the following:

change:function(t,value,opts){
                           if (opts == -1){
                               t.getThumb().setCls("slider-against");
                           }else if (opts== 0){
                               t.getThumb().setCls("slider-neutral");
                           }else if (opts == 1){
                               t.getThumb().setCls("slider-for");
                           }
                           
                       }

Is there a way to access the sliderfield thumb? getThumb is no longer available in PR3

The 'slider' part of the field is now it's own component; Ext.slider.Slider. You will need to access that, then you can access the thumb.

field.getComponent().getThumb(...);
