Class Ext.dd.ScrollManager
-
- | Package: | Ext.dd |
- | Defined In: | ScrollManager.js |
- | Class: | 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);
-
Note: This class uses "Point Mode" and is untested in "Intersect Mode".This class is a singleton and cannot be created directly.
