Ext.dd.ScrollManager

Provides automatic scrolling of overflow regions in the page during drag operations.

The ScrollManager configs will be used as the defaults for any scroll container registered with it, but you can also override most of the configs per scroll container by adding a ddScrollConfig object to the target element that contains these properties: hthresh, vthresh, increment and frequency. Example usage:

var el = Ext.get('scroll-ct');
el.ddScrollConfig = {
    vthresh: 50,
    hthresh: -1,
    frequency: 100,
    increment: 200
};
Ext.dd.ScrollManager.register(el);
