Forcing pack in mouse click event

[Janis Derby]

I have a sqlj file that selects about 40 different counts on tables and views and calls several different stored procedures. I also have a JFrame that has a textField for each count I need to do. When I hit the go button, I call these different methods and assign the count to the proper text field.
My problem is that this can take several minutes and I would like to know where in the counts/procedure the program is. I have the textfields gray to start out with, and a status bar. I would like the textfields to turn white and show the number of counts as well as the label in the status bar to show which count/procedure it is currently doing.
I have all the method calls in the ButtonActionPerformed method. I have called pack(), repaint(), validate() on the JFrame and even on the JPanel that the textfields sit on and nothing makes them refresh until all the counts/procedures are called and the ButtonActionPerformed returns.
Is there any way to make the textfields and label refresh during the ButtonActionPerformed method?

 
    private void setStatus(String status){
        statusLabel.setText("Status: " + status);
    }
    
    private void setTextField(JTextField textField, String count){
        textField.setBackground(java.awt.Color.white);
        textField.setText(count);
        
        this.repaint();
        this.pack();
        this.validate();
        allCountsPanel.validate();
        allCountsPanel.updateUI();
        allCountsPanel.repaint();
    }
    
    private void getCountsButtonActionPerformed(java.awt.event.ActionEvent evt) {
        for(int j=0; j<testNumbers.size(); j++){
            i=Integer.parseInt((String)testNumbers.get(j));
            setStatus("Calling count on TP_Service");
            setTextField(tpServiceTextField, tc.selectTpService(i));
            setStatus("Calling count on TP_RenderedService");
            setTextField(tpRendServTextField, tc.selectTpRendServ(i));
            setStatus("Calling count on TP_MMAST MBC");
            setTextField(tpMmastTextField, tc.selectTpMmast(i));
            .
            .
            .

Hi,
The problem is that you are doing it within the event dispatching thread. All refresh will happen only when the control is relinquished.
To solve your problem, you need to perform those tasks in a background thread.

Thanks! That's what I needed.
One more question..
If you have a method that takes a parameter and uses it in an anonymous class it must be declared as final. Why?

    void updateStatus(final int i) {
        Runnable doSetProgressBarValue = new Runnable() {
            public void run() {
                progressBar.setValue(i);
            }
        };
