@DefaultProperty("content") public class ScrollPane extends Control
A Control that provides a scrolled, clipped viewport of its contents. It allows the user to scroll the content around either directly (panning) or by using scroll bars. The ScrollPane allows specification of the scroll bar policy, which determines when scroll bars are displayed: always, never, or only when they are needed. The scroll bar policy can be specified independently for the horizontal and vertical scroll bars.

The ScrollPane allows the application to set the current, minimum, and maximum values for positioning the contents in the horizontal and vertical directions. These values are mapped proportionally onto the layoutBounds of the contained node.

ScrollPane layout calculations are based on the layoutBounds rather than the boundsInParent (visual bounds) of the scroll node. If an application wants the scrolling to be based on the visual bounds of the node (for scaled content etc.), it needs to wrap the scroll node in a Group.

ScrollPane sets focusTraversable to false.

This example creates a ScrollPane, which contains a Rectangle: 

 Rectangle rect = new Rectangle(200, 200, Color.RED);
 ScrollPane s1 = new ScrollPane();
 s1.setPrefSize(120, 120);
 s1.setContent(rect);
