Bounded Range Components - The Definitive Guide to Java Swing - page 418

JScrollBar Properties
After you've created a JScrollBar , it may become necessary to modify its underlying data
model. You can get the model with the public BoundedRangeModel getModel() method, and
then modify the model directly. More likely, you would just call the appropriate methods of the
component:

• setValue(int newValue) , setExtent(int newValue) , setMinimum(int newValue)

• setMaximum(int newValue)

These methods act as proxies and redirect any calls to the equivalent model method.

■ Caution Although supported, it's not recommended that you modify a JScrollBar 's orientation after
displaying the component. This could seriously diminish the user's satisfaction and encourage the user to find
a solution from another vendor!

In addition to the data model properties, Table 12-1 shows the 16 properties of JScrollBar .
