Inner class problem

Question

Hi.
I want 100 buttons to be displayed, 10 rows with 10 cols. To create all buttons I do a loop, and calls a function that creates and adds the buttons to the panel.
Here is the code sample.
<CODE>
// Here I adds the buttons
for (int i = 0; i < 10; i++) {
   for (int y = 0; y < 10; y++) {               
      addButton(this, title,
      new ActionListener() {
         public void actionPerformed(ActionEvent e) {
            check(i,y);
      },i,y,1,1);
// The function to add buttons
public void addButton(Container c, String title, ActionListener a, int x, int y, int w, int h) {
buildConstraints(gbco,y,x,w,h,0.0,0.0);
JButton b = new JButton();
b.addActionListener(a);
b.setText(title);
b.setSize(40,40);
Insets s = new Insets(0,0,0,0);
b.setMargin(s);
c.add(b,gbco);
</CODE>
The problem is that I want to access i, y (loop variables - wich represents the cordinates: i = rows and y = cols) in the actionPerformed() function (when I call check(i,y). But I cant access them, cause they are accessed within an inner class, and in order to do that, I have to declare i,y final. Wich I obvious cant do since they increase every time they loop.
So any suggestions on how to do this in another way, or how to get around this problem(eg. displaying 100 buttons, and when I click one, it should know what cordinates it has)?

Answer 1

one (of many) ways to do that is to make your own class. It would look something kinda like this...
public class smartJButton
private JButton jb;
private int row;
private int column;
public smartJButton( int r, int col, JButton button )
  jb = button;
  jb.addActionListener(new java.awt.event.ActionListener()
   public void actionPerformed(java.awt.event.ActionEvent evt)
   { showCoordinates(); }
  row = r;
  column = col;
public void getCoordinates()
{ System.out.println("I am at row "+row+" and column "+column"); }
}
