Question

Im trying to make a JDialog that will show the user a dynamic message on a JLabel.
The message should be a count from 1 to 10 (and it should be changing a number every second).
the thing is , when im debugging it – it’s stops right after the “dia.setVisible(true);” , and will not proceed unless i will close the JDialog .
is there any possible way of fixing it?
Thanks.

Take a look at the code :

    @Override
public void run() {

    dia = new JDialog(parentDialog, true);
    dia.setLocationRelativeTo(parentFrame);


    String text = "Text ";
    dia.setSize(300, 150);
    jl = new JLabel(text);
    dia.getContentPane().add(jl);
    dia.setVisible(true);
    for (int i = 0; i < 10; i++) {
        try {
            Thread.sleep(1000);
            jl.setText(text + " " + i);

        } catch (InterruptedException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }
    }

}

Answer 1

• don’t use Thread.sleep(int) for Swing GUI, caused freeze of untill Thread.sleep(int) ended

• use Swing Timer instead of locking Swing GUI by usage of Thread.sleep(int)

• don’t use dia.setSize(300, 150), learn how LayoutManager works
