20  * preference page with an adapatable element.
21  * <p>
22  * Subclasses must implement the <code>createContents</code> framework method
23  * to supply the property page's main control.
24  * </p>
25  * <p>
26  * Subclasses should extend the <code>doComputeSize</code> framework method to
27  * compute the size of the page's control.
28  * </p>
29  * <p>
30  * Subclasses may override the <code>performOk</code>,
31  * <code>performApply</code>,<code>performDefaults</code>,
32  * <code>performCancel</code>, and <code>performHelp</code> framework
33  * methods to react to the standard button events.
34  * </p>
35  * <p>
36  * Subclasses may call the <code>noDefaultAndApplyButton</code> framework
37  * method before the page's control has been created to suppress the standard
38  * Apply and Defaults buttons.
