Java SwingWorker while using SWT

Question

I have a problem as follows:

I've written a simple minimalistic Application that utilizes the SWT for the GUI. In a specific tab, where it displays a table that get's filled with Informition via a REST Api Call. Additionaly, i have another method to export this table into a CSV-file. This works absolutely fine. Now I need some kind of autoupdate/-export for which I implemented a Swing-Worker like this:

    protected class AutoExportWorker extends SwingWorker<Integer, String> {


    @Override
    public Integer doInBackground() throws Exception {


        System.out.println("Worker Start!");

        while (true) {
            System.out.println("In Loop");

                            //updateTable();
                            //exportToCSV();

            for (int i = 0; i<interval;i++) {

                System.out.println(interval - i);
                Thread.sleep(1000);

            }
        }   
    }

The Class is a subclass of the Composite which views the table and holds the methods "updateTable()" and "exportsToCSV()". Now I'm aware that this Worker doesn't do much when I call these Methods but I can't figure out, how to do this correctly. Do you have any hints for me?

Best regards!

If you are using Eclipse RCP, you should use Jobs API. In plain SWT, there is no built-in solution. You need to use Display.asyncExec to update the table.
