Example

To execute the example, the HTML page must contain the TabSheet component named tabSheet (see Example of Creating the TabSheet Component). Scroll the table downward, and change the scrollbars appearance so that they do not cover the whole table:

tabSheet.setVerticalExpandVolume(2);
// Get vertical scrollbar element
var hScrollBar = tabSheet.getVScrollBar();
// Scroll the table vertically 
hScrollBar.scrollTo(50, True);
// Change appearance of scrollbar panels
tabSheet.setIsScrollBarPartial(True);
