I have a JFrame to display after a button is clicked. The following
JFrame appears, but the label text does not appear until the thread is
completed. Any advise:

public void run(){
JPanel panel = new JPanel();  // create pane content object
JLabel prompt = new JLabel("Processing log files");

panel.add(prompt);

Container contentPane = myFrame.getContentPane();
contentPane.add(panel);

myFrame.setTitle("Processing logs...Please Wait");
myFrame.setBounds(100,100,350,75); // position frame
myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
myFrame.toFront();
panel.add(prompt);
myFrame.setVisible(true);
myFrame.pack();
System.out.println ("pack1 done");
myFrame.repaint();
myFrame.pack();
}
