I updated the simple Scrollbar class with a few new features.
It now has a horizontal scroll option. Setting this option allows the scrollbar to scroll horizontally.
You can now set the position of the scroll bar using the setValue() method.
It also has an enabled property. The property when set to true enables the scrollbar. Setting enabled to false disables the scrollbar. If the scroll bar is disabled you can still cal it’s setValue() method. These could be used in combination to create a progress bar or other element that would move on it’s own with being dragged. It’s also useful at times when you need to disable the scrollbar.
The new features are documented in the original post here.
