Adding image to Jbutton with foreground label

Question

Friends, i m trying add image to my Jbutton using seticon method but it hide the text label on the button. Here is the code :

      try {
        Image img = ImageIO.read(getClass().getResource("image.jpg"));
        studentsButton.setIcon(new ImageIcon(img));         
      } catch (IOException ex) {
      }

And i m using swing in eclipse without init()/paint()/graphics, its simple frame in main method.

Solution

Simply use

studentsButton.setHorizontalTextPosition(AbstractButton.CENTER);
studentsButton.setVerticalTextPosition(AbstractButton.BOTTOM);

This will simply place the Text below the Image. And the output will be like this :

Here is one code example for your help having as output:

import java.awt.*;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;
import javax.swing.*;
import javax.imageio.ImageIO;

public class ButtonImageExample
{
    private JButton imageButton;
    private ImageIcon image;

    private void displayGUI()
    {
        JFrame frame = new JFrame("Button Image Example");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        JPanel contentPane = new JPanel();
        try
        {
            image = new ImageIcon(ImageIO.read(
                    new URL("http://i.imgur.com/6mbHZRU.png")));
        }
        catch(MalformedURLException mue)
        {
            mue.printStackTrace();
        }
        catch(IOException ioe)
        {
            ioe.printStackTrace();
        }       

        imageButton = new JButton("Button Text");
        imageButton.setIcon(image);
        imageButton.setHorizontalTextPosition(AbstractButton.CENTER);
        imageButton.setVerticalTextPosition(AbstractButton.BOTTOM);

        contentPane.add(imageButton);

        frame.setContentPane(contentPane);
        frame.pack();
        frame.setLocationByPlatform(true);
        frame.setVisible(true);
    }

    public static void main(String... args)
    {
        SwingUtilities.invokeLater(new Runnable()
        {
            public void run()
            {
                new ButtonImageExample().displayGUI();
            }
        });
    }
}

Could you also tell me how to change background image for a JPanel without using subclass?

[Guillaume Polet]

@MachMitch use a JLabel for that

[nIcE cOw]

As suggested by @GuillaumePolet, you can use JLabel for this, set it's Layout and add components to it. Give me some time for the example.

[Mach Mitch]

really nice example but i have already designed my layout and now adding everything to JLabel would be very difficult since i have used 16 JPanels already.....it will be easy to provide panel a background image instead of messing with the whole layout
