Java Tutorial/Swing/CompoundBorder

14. CompoundBorder: to combine borders before associating them with a component.

A compound border is composed of two border objects. You can nest an inside border within the insets of an outside border.

   <source lang="java">

public CompoundBorder() public static CompoundBorder createCompoundBorder()

public CompoundBorder(Border outside, Border inside) Border compoundBorder = new CompoundBorder(lineBorder, matteBorder);

public static CompoundBorder createCompoundBorder(Border outside, Border inside) Border compoundBorder = BorderFactory.createCompoundBorder(lineBorder, matteBorder);</source>

14. CompoundBorder with double line borders and Lowered Bevel Border

   <source lang="java">

import java.awt.BorderLayout; import java.awt.Color; import java.awt.event.WindowAdapter; import java.awt.event.WindowEvent; import javax.swing.BorderFactory; import javax.swing.JFrame; import javax.swing.JLabel; import javax.swing.border.Border; import javax.swing.border.rupoundBorder; import javax.swing.border.LineBorder; public class CompoundBorderLabel extends JFrame {

 JLabel label = new JLabel("A label with some borders");
 public CompoundBorderLabel() {
   setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   Border border1 = new CompoundBorder(LineBorder.createBlackLineBorder(),
       BorderFactory.createLineBorder(Color.red, 20));
   Border border2 = new CompoundBorder(border1, BorderFactory
       .createLoweredBevelBorder());
   label.setBorder(border2);
   getContentPane().add(label, BorderLayout.CENTER);
   pack();
 }
 public static void main(String arg[]) {
   CompoundBorderLabel m = new CompoundBorderLabel();
   m.setVisible(true);
 }

}</source>

14. Creating CompoundBorder with LineBorder

   <source lang="java">

import java.awt.Color; import java.awt.Container; import java.awt.GridLayout; import javax.swing.BorderFactory; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.border.Border; import javax.swing.border.rupoundBorder; import javax.swing.border.LineBorder; public class ACompoundBorder {

 public static void main(String args[]) {
   JFrame frame = new JFrame("Compound Borders");
   frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
   Border lineBorder = LineBorder.createBlackLineBorder();
   Border bevelBorder = BorderFactory.createRaisedBevelBorder();
   Border bevelLineBorder = new CompoundBorder(bevelBorder, lineBorder);
   JButton bevelLineButton = new JButton("Bevel Line");
   bevelLineButton.setBorder(bevelLineBorder);
   Border redBorder = BorderFactory.createLineBorder(Color.MAGENTA, 2);
   Border orangeBorder = BorderFactory.createLineBorder(Color.BLUE, 2);
   Border yellowBorder = BorderFactory.createLineBorder(Color.YELLOW, 5);
   Border greenBorder = BorderFactory.createLineBorder(Color.GREEN, 2);
   Border blueBorder = BorderFactory.createLineBorder(Color.ORANGE, 4);
   Border magentaBorder = BorderFactory.createLineBorder(Color.RED, 3);
   Border twoColorBorder = new CompoundBorder(magentaBorder, blueBorder);
   Border threeColorBorder = new CompoundBorder(twoColorBorder, greenBorder);
   Border fourColorBorder = new CompoundBorder(threeColorBorder, yellowBorder);
   Border fiveColorBorder = new CompoundBorder(fourColorBorder, orangeBorder);
   Border sixColorBorder = new CompoundBorder(fiveColorBorder, redBorder);
   JButton rainbowButton = new JButton("Rainbow");
   rainbowButton.setBorder(sixColorBorder);
   Container contentPane = frame.getContentPane();
   contentPane.setLayout(new GridLayout(1, 2));
   contentPane.add(bevelLineButton);
   contentPane.add(rainbowButton);
   frame.setSize(300, 100);
   frame.setVisible(true);
 }
