How to add background images to Oracle Java programs

The following articles mainly describe how to add beautiful background images to the actual Oracle Java-related applications. The actual application code that can be executed after sorting is as follows: I hope this article will help you in its practical application.

 
 

  
  
Import java. awt .*;
  
  
Import javax. swing .*;
  
  
Public class TestBackgroundColor extends JFrame
  
  
{
  
  
Public static void main (String [] args)
  
  
{
  
  
TODO Auto-generated method stub
  
  
TestBackgroundColor tbc = new TestBackgroundColor ();
  
  
Tbc. setVisible (true );
  
  
}
  
  
Private JPanel imagePanel;
  
  
Private ImageIcon background;
  
  
Public TestBackgroundColor ()
  
  
{
  
  
Background = new ImageIcon ("gradient background 14.png ");
 
 

Background Image

 
 

  
  
JLabel label = new JLabel(background); 
 
 

Display the background image in a tag

Set the label size and position to the image to fill the entire panel.

 
 

  
  
label.setBounds(0,0,background.getIconWidth(),background.getIconHeight()); 
 
 

Convert the content pane to JPanel. Otherwise, you cannot use the setOpaque () method to make the content pane transparent.

 
 

  
  
imagePanel = (JPanel)this.getContentPane();  
  
  
imagePanel.setOpaque(false);  
 
 

The default layout manager of the content pane is BorderLayout.

 
 

  
  
ImagePanel. setLayout (new FlowLayout ());
  
  
ImagePanel. add (new JButton ("test button "));
  
  
This. getLayeredPane (). setLayout (null );
 
 

Add the background image to the bottom layer of the layered pane as the background

 
 

  
  
this.getLayeredPane().add(label,new Integer(Integer.MIN_VALUE));  
  
  
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);  
  
  
this.setSize(background.getIconWidth(),background.getIconHeight());  
  
  
this.setVisible(true);  
  
  
}  
  
  
}
