Help with JButton

[geoffreybarwise]

Hi!

I am currently developing a game - poker dice - for a major project in matric. The project is coming along swimmingly , but I still don't know how to make a JButton flash / blink. The intention is to attract the user's attention to the particular button.

Please can someone help me with the code / method for this problem. I am coding in Java format.

Thanks a million

If you mean Jbutton blinks,

do it in thread...

How about the use of a Timer. Define a array of colors, and with the timer tick change the background color of it.

Yes, why not. Try something like this. This is not what exactly you need, but the logic is there.

Code:

import java.awt.*;
import java.awt.event.*;
import java.util.Random;
import javax.swing.*;

public class ButtonBlinker extends JFrame {
    
    private JButton btn;
    final Color[] colors = {Color.RED, Color.GREEN, Color.ORANGE};
    
    ButtonBlinker() {
        Container content = getContentPane();
        
        btn = new JButton("Blinker");
        
        content.add(btn);
        
        pack();
        setVisible(true);
    }

    public static void main(String[] args) {
        new ButtonBlinker().blinkTimer();
    }

    private void blinkTimer(){
        Timer tt = new Timer(2000, new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                btn.setBackground(colors[colorChoocer()]);
            }
        });
        tt.start();        
    }
    
    private int colorChoocer() {
        return new Random().nextInt(3);
    }
}
