question: private JComponent createDetailPanel ( Throwable error ) { StackTraceList stl = new StackTraceList ( error ) ; JScrollPane detailPane = new ExtendedJScrollPane ( stl ) ; detailPane . setPreferredSize ( new Dimension ( getWidth ( ) , 200 ) ) ; detailPane . setBorder ( null ) ; return detailPane ; }
target:  Creates a Panel for the error details and attaches the exception to it, but doesn't add the Panel to the dialog.
