public class ScrollPaneSelector
extends JComponent

ScrollPaneSelector is a little utility class that provides a means to quickly scroll both vertically and horizontally on a single mouse click, by dragging a selection rectangle over a "thumbnail" of the scrollPane's viewport view.

Once the selector is installed on a given JScrollPane instance, a little button appears as soon as at least one of its scroll bars is made visible.
