Blocking mainthread till gui event

Question

I know this has been posted many a times .
But i'm unable to make out the solution specific to my code . I,ve created a class MyFrame extending Jframe. i've placed a button on it.I need this class to define a method get_table() which returns a specific datatable only wen the button is clicked . in other words calling get_table should pause or block the main thread until the button is clicked; I've implemented spinlocking before using a while loop in the main thread. Give me an alternative solution please ;

Why should we help you?Please ignore this comment. I got told off by sabre(And rightly so) I was just a bit fed up.
Please read the following Swing tutorial on GUI and Threads.
[http://java.sun.com/products/jfc/tsc/articles/threads/threads1.html]
Sorry about not posting any code , jamesybaby . I'm a newbie :-) ;
About the tutorial, it's great .But I never understood how to apply it into my context ; You recommend using invokeandwait() ?
Here's my code for MyFrame
public class MyFrame extends javax.swing.JFrame implements ActionListener {
    public MyFrame() {
        super();
        initComponents();
        panel = new MyRow[9];
        for (int i = 0; i < 9; i++) {
            panel[i] = new MyRow();
            getContentPane().add(panel);
action = new JPanel();
_OK = new JButton("Solve");
_OK.addActionListener(this);
action.add(_OK);
add(action);
MyFrame(MyTable t) {
initComponents();
panel = new MyRow[9];
for (int i = 0; i < 9; i++) {
panel[i] = new MyRow(t.getrow(i+1));
getContentPane().add(panel[i]);
action = new JPanel();
_OK = new JButton("Solve");
_OK.addActionListener(this);
action.add(_OK);
getContentPane().add(action);
public int getData(int row, int col) {
return panel[row].getBox(col);
private void initComponents() {
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
getContentPane().setLayout(new javax.swing.BoxLayout(getContentPane(), javax.swing.BoxLayout.PAGE_AXIS));
pack();
MyRow panel[];
JPanel action;
JButton _OK;
MyTable table;
private boolean done = false;
boolean isdone() {
return done;
public void actionPerformed(ActionEvent e) {
done = true;
public MyTable getdata(){
MyTable t=new MyTable();
try{
catch(Exception e){
for (int i = 0; i < 9; i++) {
for (int j = 0; j < 9; j++) {
if (getData(i, j) == 0) {
continue;
} else {
t.setdata(i+1, j+1, getData(i, j));
return t;
}After this i need to call getdata from the main function to  store the returned table.
The table should only be returned when the button is clicked
And thank ya sabre150
