calling SwingWorker cance

Show all headers | View raw

  To: comp.lang.java.gui
hello,

i realize that when after i call SwingWorker cancel and try to wait
until the task is really canceled (through SwingWorker.get), i will
get exception as stated in http://java.sun.com/docs/books/tutorial/uiswing/concurrency/cancel.html

Note: If get is invoked on a SwingWorker object after its background
task has been cancelled, java.util.concurrent.CancellationException is
thrown.

Hence, i was wondering after the CancellationException caught, when
the time the next statement is executed, does the task is really
cancelled?

thanks

    private void formWindowClosing(java.awt.event.WindowEvent evt)
{
// TODO add your handling code here:
        try
        {
            marketTask.cancel(false);
            marketTask.get();
        }
        catch(InterruptedException exp) {
        }
        catch(java.util.concurrent.ExecutionException exp)
{
        }
        catch(java.util.concurrent.CancellationException exp)
{
        }

// So, does market Task really cancelled???
    }
