How to add a background image to Java

First, import the relevant packages:

Import Java.awt.BorderLayout;

Import Java.awt.Container;

Import Javax.swing.ImageIcon;

Import Javax.swing.JFrame;

Import Javax.swing.JLabel;

Import Javax.swing.JPanel;

You can also use:

Import java.awt.*;

Import javax.swing.*;

Next, create a Java form object and set it to visible

Eg:jfram frame = JFrame ();//Create a form
Frame.setvisible (TRUE);//Set form visible, invisible by default

Finally, write the following code:

/*
* The following 7 lines add a background picture to the form
*/
ImageIcon img = new ImageIcon ("e:\\1" + ". gif");//This is a background image
JLabel Imglabel = new JLabel (IMG);//Place the background map in the label.
Frame.getlayeredpane (). Add (Imglabel, New Integer (Integer.min_value));//Note This is the key, add the background tag to the Jfram layeredpane panel.
Imglabel.setbounds (0,0,img.geticonwidth (), Img.geticonheight ());//Set the position of the background label
Container Cp=frame.getcontentpane ();
Cp.setlayout (New BorderLayout ());
((JPanel) CP). Setopaque (false); Notice here that the content panel is set to transparent. This allows the background in the Layeredpane panel to be displayed.

Write a try now!!!

The complete code is as follows:

Package the eighth chapter;

Import Java.awt.BorderLayout;

Import Java.awt.Container;

Import Javax.swing.ImageIcon;

Import Javax.swing.JFrame;

Import Javax.swing.JLabel;

Import Javax.swing.JPanel;

public class Myfirstframe extends JFrame {

/**

* Listen to the Valley ~

* Version 1.0

*/private static final long serialversionuid = 1L;

public static void Main (string[] args) {

TODO auto-generated Method Stub

Myfirstframe frame=new myfirstframe ();

Frame.setvisible (TRUE);//Set form visible, invisible by default

/*

* The following 7 lines add a background picture to the form

*/

ImageIcon img = new ImageIcon ("E:\\1.gif");//This is a background image

JLabel Imglabel = new JLabel (IMG);//Place the background map in the label.

Frame.getlayeredpane (). Add (Imglabel, New Integer (Integer.min_value));//Note This is the key, add the background tag to the Jfram layeredpane panel. Imglabel.setbounds (0,0,img.geticonwidth (), Img.geticonheight ());//Set the position of the background label

Container Cp=frame.getcontentpane ();

Cp.setlayout (New BorderLayout ());

((JPanel) CP). Setopaque (false); Notice here that the content panel is set to transparent. This allows the background in the Layeredpane panel to be displayed.

}

Public Myfirstframe () {

Super (); Inherits the parent class construction method Settitle ("form created with the JFrame class");

SetBounds (100,100,315,320); Set the form display position and size

System.out.println (Getforeground ());

Getcontentpane (). setlayout (null);//set to not take any layout manager

Setdefaultcloseoperation (Jframe.exit_on_close); }

}
