How to make a JButton unclickable after clicking on it?

Question

Here's my code :

for(int row = 0; row < 10; row++)
{
    for(int col = 0; col < 10; col++)
    {
            button = new JButton();

            panel_1.add(button);
     }
 }

    button.addActionListener(new ActionListener()
    {
        public void actionPerformed(ActionEvent e)
        {
            //If Button is clicked, make the button unclickable
            if(button == (JButton)e.getSource())
            {
                button.setEnabled(false);

            }
        }

    });

I want to make any JButton I click from this 10 x 10 grid button layout unclickable; however, this method only makes no other that the right button unclickable, What's wrong? I have put the ActionListener outside the for-Loop that is responsible for making the buttons. I don't know what's going on.

Here's what it looks like :

Edit: bsd code works. Add ActionListener before adding the buttons or something along those lines.

Answer 1

You only add the ActionListener to the last button created.

You need to add the ActionListener to every button created inside the loop.

So the code should be something like:

ActionListener al = new ActionListener()
{
    public void actionPerformed(ActionEvent e)
    {
         JButton button = (JButton)e.getSource();
         button.setEnabled( false );
    }
};

for(int row = 0; row < 10; row++)
{
    for(int col = 0; col < 10; col++)
    {
            button = new JButton();
            button.addActionListener( al );
            panel_1.add(button);
     }
 }

Answer 2

Since you want to disable all buttons in your panel. The button action listener should be inside the for loop.

button = new JButton();
button.addActionListener(new ActionListener()
{
    public void actionPerformed(ActionEvent e)
    {
        //If Button is clicked, make the button unclickable
        if(button == (JButton)e.getSource())
        {
            button.setEnabled(false);

        }
    }

});
