Saving JFrame

[jralexander]

Hi,
I am wondering if it is possible to save a JFrame as a picture file? If so some help on doing this would be great as I am unsure if you can do this let alone know where to begin. Thanks in advance for the help.

I haven't done this but you can draw the JFrame I believe using a BufferedImage's Graphics object and the JFrame's paint command and then save this as a JPG. Again, I've not done this but I think I've seen it somewhere.

This program will capture a JFrame except not the title bar, and I haven't yet figured out how to do that:

import java.awt.Dimension;
import java.awt.Graphics;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;

import javax.imageio.ImageIO;
import javax.swing.JButton;
import javax.swing.JComponent;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

public class PaintJFrame
{
  private static final Dimension MAIN_SIZE = new Dimension(400, 300);
  private JPanel mainPanel = new JPanel();
  
  public PaintJFrame()
  {
    JButton makeImageBtn = new JButton("Make Image");
    makeImageBtn.addActionListener(new BtnListener());
    mainPanel.add(makeImageBtn);
    mainPanel.setPreferredSize(MAIN_SIZE);
  }
  
  public JComponent getPanel()
  {
    return mainPanel;
  }
  
  private class BtnListener implements ActionListener
  {
    public void actionPerformed(ActionEvent arg0)
    {
      JFrame win = (JFrame)SwingUtilities.getWindowAncestor(mainPanel);
      Dimension size = win.getSize();
      //BufferedImage image = new BufferedImage(size.width, size.height, BufferedImage.TYPE_INT_RGB);
      BufferedImage image = (BufferedImage)win.createImage(size.width, size.height);
      Graphics g = image.getGraphics();
      win.paint(g);
      g.dispose();
      try
      {
        ImageIO.write(image, "jpg", new File("MyFrame2.jpg"));
      }
      catch (IOException e)
      {
        e.printStackTrace();
      }
    }
  }
  
  private static void createAndShowGUI()
  {
    JFrame frame = new JFrame("PaintJFrame Application");
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.getContentPane().add(new PaintJFrame().getPanel());
    frame.pack();
    frame.setLocationRelativeTo(null);
    frame.setVisible(true);
  }

  public static void main(String[] args)
  {
    javax.swing.SwingUtilities.invokeLater(new Runnable()
    {
      public void run()
      {
        createAndShowGUI();
      }
    });

  }
}

I'll try the code you posted I am making a program that allows the user to create a family tree and I just need to save the picture of the tree so this should work I'll try it out and post the results.

in the top right corner of ur keyboard(PC) theres a button that says

Prt Sc
Sys Rq

when u have the JFrame up hit that button open up paint hit the edit button and then copy. then u can save it as .jpg or .gif or wutever else u like.

I think he means he wants a save option so the user doesn't have to do that because the save command would automatically do it for them
