All Implemented Interfaces:

java.lang.Runnable, java.util.concurrent.Future<java.lang.Exception>, java.util.concurrent.RunnableFuture<java.lang.Exception>

public class ExportWorker
extends MidicaWorker

This class is used to export a file in the background while a WaitView is shown.

This worker is executed in the background before the (blocking) setVisible() method of the (modal) waiting dialog is called. That causes the execution of doInBackground() that exports the file.

After the export work is finished, MidicaWorker.done() is called and closes the waiting dialog.
