Scrollbar UI is a component that fully replaces the browser's scrollbar with a complete custom one. Currently SK Scrollbar looks very similar to Mac OSX Lion native scroller, its basically the same. That is why by default we don't apply it on Chrome/Safari under Mac OSX Lion (Firefox has some issues with the native scroller so we apply the custom scroller there). This UI may have many options, including scroller track, [+] and [-] buttons, and can be easily styled. The constructor can be a good base for more advanced UIs and controls, e.g. components in which we have interfaces like scrollbar, slider, etc.

  • Creating a simple Scrollbar UI:
var options = {
   autohide   : true,
   buttons    : true,
   horizontal : true
// my-scrollbar can be a DOMElement or an ID
new SK.UI.Scrollbar( 'my-scrollbar', options );
