SWT and Threads

[mehdi]

Hi,
I would like to run a thread to simulate a clock on my application SWT
so i tried to write this code :

Code: Select all

public class Clock implements Runnable {

    private Label label;

    /**
     * @param l
     * 
     */
    public Horloge(Label l) {

        this.label = l;
        run();
    }

    public void run() {
        label.getDisplay().asyncExec(new Runnable() {
            public void run() {
                Calendar c = Calendar.getInstance();
                int h = c.get(Calendar.HOUR);
                int m = c.get(Calendar.MINUTE);
                int s = c.get(Calendar.SECOND);
                label.setText(h + ":" + m + ":" + s);
                try {
                    Thread.sleep(1000);
                } catch (Exception e) {
                    e.printStackTrace();
                }
            }

        });

    }

}


and in a shell : label_clock with my thread

Code: Select all


Clock c  = new Clock(label_horloge);
       while (!shell.isDisposed()) {
            shell.getDisplay().asyncExec(h);
            if (!display.readAndDispatch())
                display.sleep();
        }


But it takes too many memory on my machine, i don't find my probelme please help me.....

I'm not entirely sure what problem you are asking for help on. Is this a runtime issue or design time issue?

If it is a design time issue, please provide us with any exception log details as well as a complete example (not a fragment).

If it is a runtime issue, you should post your question to the Eclispe SWT newsgroup.
