Selenium Webdriver dragging Scroll Bar of a Table or Window

after a lot of searching i stumbled upon this piece of code (Java):

Actions dragger=new Actions(drive);

WebElement draggablePartOfScrollbar= drive.findElement(By.className("mCSB_dragger_bar"));

int numberOfPixelsToDragTheScrollbarDown=300;

dragger.moveToElement(draggablePartOfScrollbar).clickAndHold().moveByOffset(0,numberOfPixelsToDr
agTheScrollbarDown).release().perform();


May be further modified using loops and specific logics.
