How to copy selected text from one text area to another E-mail

JTextArea

The Java Swing tip illustrates a method of copying selected text from one text area to another. A quick review of how it works is, selected and copied text is saved on the "clipboard" in your computer and then pasted (transfered) to a text editor. The copied text will remain on the clipboard until you copy something else or clear the clipboard.

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class TextAreaDemo extends JFrame {
   private JTextArea t1, t2;
   private JButton copy;

   public TextAreaDemo() 
   {
      super"TextArea Demo" );

      Box b = Box.createHorizontalBox();

      String s = "This is a demo string to\n" +
                 "illustrate copying text\n" +
                 "from one TextArea to \n" +
                 "another TextArea using an\n"+
                 "external event\n";

      t1 = new JTextAreas, 1015 );
      b.addnew JScrollPanet1 ) );

      copy = new JButton"Copy >>>" );
      copy.addActionListener(
         new ActionListener() {
            public void actionPerformedActionEvent e )
            {
               t2.setTextt1.getSelectedText() );
            }
         }
      );
      b.addcopy );

      t2 = new JTextArea1015 );
      t2.setEditablefalse );
      b.addnew JScrollPanet2 ) );

      Container c = getContentPane();
      c.add);    // Box placed in BorderLayout.CENTER
      setSize425200 );
      show();
   }

   public static void mainString args[] )
   {
      TextAreaDemo app = new TextAreaDemo();

      app.addWindowListener(
         new WindowAdapter() {
            public void windowClosingWindowEvent e )
            {
               System.exit);
            }
         }
      );
   }
}
