Class Ext.dd.ScrollManager

Package:Ext.dd
Defined In:ScrollManager.js
Class:ScrollManager
Extends:Object

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);
Note: This class uses "Point Mode" and is untested in "Intersect Mode".

This class is a singleton and cannot be created directly.
