Class ScrollbarLayout

com.sas.visuals.ScrollbarLayout

All Implemented Interfaces:

java.awt.LayoutManager, java.io.Serializable

public class ScrollbarLayout
implements java.awt.LayoutManager, java.io.Serializable

ScrollbarLayout is layout manager which works like a BorderLayout to layout out scrollbars within a container. ScrollbarLayout, however, is different from BorderLayout in that it does not stretch the scrollbars in the horizontal positions to be the width of the component if there is a vertical scrollbar visible.

Scrollbars have to be added in the North, South, East or West positions in order to be displayed on one of the edges of the container, similar to BorderLayout. The actual location of the scrollbars, however, is determined by the location property which is set during construction of a ScrollbarLayout. The possible values are: TOP, LEFT, BOTTOM, RIGHT or a combination of two of these. For example, to have the scrollbars on the right and at the bottom BOTTOM | RIGHT would be specified in the constructor.

Any component can be added to using Center
