22  /** Exception that is thrown when the process is about to perform some
23  * action that requires user confirmation. It can be useful when there
24  * is a call to a method which cannot open a dialog, but still would like
25  * to ask the user a question. It can raise this exception and higher level
26  * parts of the system can/should catch it and present a dialog to the user
27  * and if the user agrees reinvoke the action again.
28  * <P>
29  * The <code>getLocalizedMessage</code> method should return the user question,
30  * which will be shown to the user in a dialog with OK, Cancel options and
31  * if the user chooses OK, method <code>ex.confirmed ()</code> will be called.
