How can I create a frame with round edges in Java. I already created a round edge button

Question

import java.awt.*; import javax.swing.*; import java.awt.geom.*; import java.awt.event.*; import javax.swing.border.*; public class ChangeButtonShape { public static void main(String[] args) { JFrame frame = new JFrame(); frame.getContentPane().setLayout(null); JLabel l=new JLabel("Name"); final JTextField text=new JTextField(20); JButton button = new JButton("Go"); //button.setBackground(Color.lightGray); l.setBounds(10,10,100,20); text.setBounds(100,10,180,20); button.setBounds(10,40,50,20); button.setBorder(new RoundedBorder(10)); frame.add(l); frame.add(text); frame.add(button); button.addActionListener(new ActionListener(){ public void actionPerformed(ActionEvent e){ String st=text.getText(); JOptionPane.showMessageDialog(null,"Hello "+st); } }); frame.setSize(300,150); frame.setVisible(true); } } class RoundedBorder implements Border { int radius; RoundedBorder(int radius) { this.radius = radius; } public Insets getBorderInsets(Component c) { return new Insets(this.radius+1, this.radius+1, this.radius+2, this.radius); } public boolean isBorderOpaque() { return true; } public void paintBorder(Component c, Graphics g, int x, int y, int width, int height) { g.drawRoundRect(x,y,width-1,height-1,radius,radius); } }

I think this is possible using AWTUtilities.setWindowShape . Take a look at this article: http://today.java.net/pub/a/today/2008/03/18/translucent-and-shaped-swing-windows.html

However, AWTUtilities is not yet publicly available as it is in the com.sun.awt package, so you should not use it. I believe it will be released in Java 7.
