If you create a custom Scrollable component and then place that component in a
JScrollPane , it will respond appropriately when the scrollbars for the JScrollPane or the
mouse wheel are moved.

JScrollPane Properties
Table 11-7 shows the 19 properties of JScrollPane .

* These properties directly map to properties of the ScrollPaneLayout manager used by the JScrollPane .
Changing one of these properties for a JScrollPane causes its layout manager to change accordingly.

■ Caution An attempt to change the layout property of JScrollPane to something other than a
ScrollPaneLayout instance or null will throw a ClassCastException at runtime, because the
layout manager used by a JScrollPane must be a ScrollPaneLayout .
