public class ScrollBar extends Control
ScrollBar sets focusTraversable to false.
This example creates a vertical ScrollBar :
import javafx.scene.control.ScrollBar;
ScrollBar s1 = new ScrollBar();
s1.setOrientation(Orientation.VERTICAL);

is the fractional amount

example, it might be 50%. If #minProperty min
were 0 and #maxProperty max
were 100 and value
were 25, then a position of .5 would indicate
that we should increment value
