With this example we shall show you how to set background color in a JLabel component in Java Desktop Applications. This will enrich and customize your GUI components.
It’s very easy to set the background color in a JLebel, as all you have to do is:
- Create a class that extends
JFrame. - Create a new
JLabel. - Use
JLabel.setBackground(Color.[COLOR_CODE])to set the foreground color. - Use add method to add the
JLabelto the frame.
Let’s see the code snippet that follows:
package com.javacodegeeks.snippets.desktop;
import java.awt.Color;
import java.awt.FlowLayout;
import javax.swing.JFrame;
import javax.swing.JLabel;
public class SetBackgroundColorInJLabel extends JFrame {
private static final long serialVersionUID = 1L;
public SetBackgroundColorInJLabel() {
// set flow layout for the frame
this.getContentPane().setLayout(new FlowLayout());
JLabel label = new JLabel("Java Code Geeks - Java Examples");
// if true the component paints every pixel within its bounds
label.setOpaque(true);
// sets the background color of this component
// the background color is used only if the component is opaque
label.setBackground(Color.BLUE);
// add label to frame
add(label);
}
private static void createAndShowGUI() {
//Create and set up the window.
JFrame frame = new SetBackgroundColorInJLabel();
//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 set background color in JLabel.
