With this tutorial we shall show you how to align Icons in JLabel. This is a very easy optimization you can perform to your JLabel.
Basically in order to align Icon in JLabel, one should follow these steps:
- Create a class that extends
JFrame. - Create a new
ImageIcon. - Create a new
JLabeland usenew JLabel(icon, JLabel.CENTER)to set the Icon to the label and center it. - Use add to add the label to the frame.
Let’s see the code snippet that follows:
package com.javacodegeeks.snippets.desktop;
import java.awt.FlowLayout;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class AlignIconInJLabel extends JFrame {
private static final long serialVersionUID = 1L;
public AlignIconInJLabel() {
// set flow layout for the frame
this.getContentPane().setLayout(new FlowLayout());
// create an ImageIcon from the specified file
ImageIcon icon = new ImageIcon("images/label.jpg");
// create a center aligned label (horizontal alignment)
JLabel label = new JLabel(icon, JLabel.CENTER);
// add label to frame
add(label);
}
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new AlignIconInJLabel();
//Display the window.
frame.pack();
frame.setVisible(true);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
//Schedule a job for the event-dispatching thread:
//creating and showing this application's GUI.
javax.swing.SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGUI();
}
});
}
}
This was an example on how to align Icon in JLabel.
