| current version: 1.2.1 |
| |
| version history: |
| 1.0 (2006-02-20) |
| initial version |
| |
| 1.1 (2006-05-17) |
| decoupled styling from this file, fixes event handling so people can scroll outside scroller if mouse is down (events now added to root element) |
| |
| 1.2 (2006-10-02) |
| changed internally "groupId" to "id" to make it consistent with other GUI elements, introduced "parentId" as a new constructor parameter for the same reason, introduced new methods "resize()" and "moveTo()" |
| |
| 1.2.1 (2006-10-03) |
| corrected a slight bug regarding DOM hierarchy of created elements |
