copy actual window to clipboard

I would like to create a screen shot of a set of diagrams. Currently I only can copy text, but no pictures :( . What I have in the moment (for test reasons with button):

Code:

---

JButton copy = new JButton("Copy");
copy.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
String selection = jt.getSelectedText();
StringSelection data = new StringSelection(selection);
clipboard.setContents(data, data);
}

---

Anyone has an idea, what I need to change to copy the current screen of the button to clipboard - Thanks

Problem is, that I cannot enter the following code into the listener.

Code:

---

Robot robot = new Robot();
BufferedImage bufferedImage = robot.createScreenCapture(new Rectangle(new Dimension(200, 200)));

---

Any idea?

Boo hoo, why not?

The error message I get is: Unhandled exception type AWTException
Sorry, I could have provided this earlier.

So handle the exception!

thanks for your advise, I have added the exception, but for some reason I still get the error. The code looks like:
copy.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
try {
Robot robot = new Robot();
BufferedImage bufferedImage = robot.createScreenCapture(new Rectangle(new Dimension(200, 200)));
}
catch (AWTException e) {e.printStackTrace();}
}
});

The error message I get: Duplicate parameter e. May you have another idea, thanks for your patience.

That error message is self explanatory. How many places in that code snippet is a parameter or variable e declared? Is is mandatory that such parameters/variables be called e?

sorry bother you again. All errors are removed and the program starts with no issues. The aim was to make a screen shot and I thought I can retreive it than with manual strg-v and place the copied image into a doc/ppt. But it is not doing it.
weekend is close and I will stop bothering you then ;-)
Code looks like this:

package demo;
import java.awt.*;
import java.awt.event.*;
import java.awt.datatransfer.*;
import java.awt.Robot;

import javax.swing.*;
import java.awt.image.BufferedImage;

public class ClipLight {
public static void main(String args[]) {
JFrame frame = new JFrame("Clip");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOS E);
final Clipboard clipboard =
frame.getToolkit().getSystemClipboard();
final JTextArea jt = new JTextArea();
JScrollPane pane = new JScrollPane(jt);
frame.add(pane, BorderLayout.CENTER);
JButton copy = new JButton("Copy");
copy.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent t) {
try {
Robot robot = new Robot();
BufferedImage bufferedImage = robot.createScreenCapture(new Rectangle(new Dimension(200, 200)));
}
catch (AWTException e) {e.printStackTrace();}
}
});
JPanel p = new JPanel();
p.add(copy);
frame.add(p, BorderLayout.SOUTH);
frame.setSize(300, 300);
frame.setVisible(true);
}
}

Programming isn't magic. You already know that a copy to the clipboard involves setting the clipboard's contents. Or was the code in your first post copied from somewhere and used blindly?

Study and understand, then adapt this code to your requirement.

ok, thanks for your patience, I will go through this.
