Customize the JOptionPane layout with updated color and image in Java
Customize the layout by changing the look and feel of the panel in which you added the component −
ImageIcon icon = new ImageIcon(new URL("http −//www.tutorialspoint.com/images/C-PLUS.png"));
JLabel label = new JLabel(icon);
JPanel panel = new JPanel(new GridBagLayout());
panel.add(label);
panel.setOpaque(true);
panel.setBackground(Color.ORANGE);Above, we have added an image and even updated the background color of the panel.
Now, set it for the text panel −
JPanel textPanel = new JPanel(new GridLayout(10, 5)); textPanel.setBackground(Color.Magenta);
The following is an example to customize the JOptionPane layout −
Example
package my;
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.GridBagLayout;
import java.awt.GridLayout;
import java.net.URL;
import javax.swing.ImageIcon;
import javax.swing.JLabel;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class SwingDemo {
public static void main(String[] args) throws Exception {
ImageIcon icon = new ImageIcon(new URL("http −//www.tutorialspoint.com/images/C-PLUS.png"));
JLabel label = new JLabel(icon);
JPanel panel = new JPanel(new GridBagLayout());
panel.add(label);
panel.setOpaque(true); panel.setBackground(Color.ORANGE);
JPanel textPanel = new JPanel(new GridLayout(10, 5)); textPanel.setBackground(Color.MAGENTA);
for (int i = 0; i < 20; i++) {
textPanel.add(new JLabel("Learn C++"));
}
JPanel panel2 = new JPanel(new BorderLayout());
panel2.add(textPanel);
panel2.add(panel, BorderLayout.EAST);
JOptionPane.showMessageDialog(null, panel2, "Course",JOptionPane.DEFAULT_OPTION);
}
}Output
