Problem with Swing -.-

Hey guys,

i have a simple question.
i have a JLabel jlbl_status in which i want so show the status of the current process.

if i set the text with the setText() method the text is not displayed in that moment.
It will be displayed after the whole action...

for example:
i have a JButton which trigges the following

Code:

---

log.info("recalculate Values");
                RecalculateTableValuesJob job;
                try {
                        job = new RecalculateTableValuesJob();
                }catch(Exception e){
                        log.error("Cant start the recalc. job");
                        e.printStackTrace();
                        return;
                }
                setStatus("Calculation...");
                setProgress(0);
                job.start();
               
                while(job.isRunning){
                        try{Thread.sleep(1000); }catch(Exception e){}
                        int p = (int)(100*xlsData.getRowCount()/job.currentIndex);
                        setProgress(p);
                }
                setProgress(100);
               
                log.info("recalculate Values Done");

---

btw. i also have the same problem with my JProgressBar ;-)

my setStatus looks like

Code:

---

public void setStatus(String text) {
                log.debug("Status: "+text);
                jlbl_status.setText(text);
        }

---

i have tried also with
jlbl_status.invalidate();
jlbl_status.revalidate();
jlbl_status.repaint();

so PLEASE!! help me... why doesnt my JLabel repaint synchronously?

hey i found out, that when i do this action in my init of the program everything works fine.
So it has something to do with my buttonevent?!
Cuz only then it doent work -.-...

You need to update your label text in the Swing Event dispatch Thread (EDT), not directly from your calculation thread. Swing provides a SwingWorker class you should use for background work that makes updating Swing components on the EDT very simple.

See Concurrency In Swing for a full explanation & tutorial, with examples.

It is a bad plan that admits of no modification...
