I am new to threads and have some simple questions.

I have a very simple test program.
I have a Frame that contains a label and a button.
I also have a thread.
The button on the frame starts the thread.
The thread loops from 1 to 10 simply updating the label on the frame to the
count value then sleeps for 1 second.
Now, when I press the button, I expect to see 1, 2, 3, ... until the counter
gets to 10.
Unfortunately, I only see the final result - 10.

Why?

What techniques should I use to correct this?

Thanks,

Below is the thread frame, followed by the thread class.

//Component initialization

  private void jbInit() throws Exception  {
    this.setLayout(borderLayout1);
    this.setSize(new Dimension(119, 153));
    this.setTitle("Frame Title");
    ThreadLabel1.setText("ThreadLabel1");

    this.add(bevelPanel1, BorderLayout.CENTER);
    bevelPanel1.add(ThreadLabel1, new XYConstraints(12, 14, 82, 35));
    bevelPanel1.add(buttonControl1, new XYConstraints(5, 68, -1, -1));
  }

  void buttonControl1_actionPerformed(ActionEvent e) {
      MyThread1.run();

      while (count++ < 10) {
          threadFrame.ThreadLabel1.setText("" + count);

          threadFrame.ThreadLabel1.repaint();
          } catch (Exception e) {};
