Thread: swing layout problems

I wanted to make my buttons round, Untitled.png. Basically, i know how to make round buttons, it is by making a class that extends JButton and do some paint stuff - BUT, when i try to add the button to the panel, sometimes it resizes its self or, doesnt obey to my damn setLocation commad. I have an idea to what this problem is caused, i think it is by the layout. Please help me do something about layouts..

import java.awt.*;
import java.awt.geom.Ellipse2D;
import javax.swing.ImageIcon;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.WindowConstants;
 
public class xButton extends JButton{
 
    private void initialize(){
        setContentAreaFilled(false);
        setCursor(new Cursor(Cursor.HAND_CURSOR));
    }
 
    public void changeLocation(Point p){
        this.setLocation(p);
    }
 
    public xButton(){
        initialize();
    }
 
    public xButton(String _text){
        super(_text);
        initialize();
    }
 
    private Dimension size = new Dimension(100,30);
    private Color back = new Color(0, 100, 240);
    private Color border = new Color(0, 80, 220);
 
    @Override
    protected void paintBorder(Graphics g) {
 
    }
 
    @Override
    protected void paintComponent(Graphics g) {
        if(getModel().isArmed()){
            g.setColor(Color.green);
        }
        else{
            g.setColor(Color.yellow);
        }
        g.fillOval(this.getLocation().x, this.getLocation().y, 39, 39);
        g.drawImage(new ImageIcon(getClass().getResource("/xComponent/buttonRestart.png")).getImage(), this.getLocation().x, this.getLocation().y, null);
 
        super.paintComponent(g);
    }
 
    Shape s = new Ellipse2D.Float(this.getLocation().x, this.getLocation().y, 40, 40);
 
    @Override
    public boolean contains(int i, int i1) {
        return s.contains(i, i1);
    }
 
    public static void main(String args[]){
        JFrame frame = new JFrame();
        xButton xb = new xButton();
        frame.setLayout(new BorderLayout());
        frame.add(xb, BorderLayout.CENTER);
        frame.setVisible(true);
        frame.pack();
        frame.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        xb.setLocation(100, 100);
    }
}

setLocation is not working..

Can you post the code so we can see what happens or make a SSCCE? It could possibly be the layout that you have chosen. If you want to have more control over the layout, try GridBagLayout.

I cant event reply... mods are preventing me to -_-

sorry if there are other code included...

those steps completed the answer to my problem thank you!
