All Implemented Interfaces:

Runnable, Future<Void>, RunnableFuture<Void>

public abstract class RecordSheetTask
extends SwingWorker<Void,Integer>

Renders one or more record sheets as a background task. The task is created using createPrintTask(List, PrinterJob, PrintRequestAttributeSet, PageFormat) for output to a printer and createExportTask(List, PageFormat, String) for export to a PDF file.

Executing the task with execute(boolean) allows showing a popup dialog with a progress bar.
