Clipboard in Java 1.1

I try to use clipboard in Java 1.1. version.
When data of clipboard is in String type it's ok,
but when data is Image, there is NullPointerException.
Transferable transferable = clipboard.getContents ( this );
variable transferable in this lines equlals null..
Help me someone please.

Use jdk 1.4 as that is the first version that supports transfering images to/from the clipboard.

Pasting Image from Mac clipboard to Java Based Application.

Hi,
I am working on "iMac 10.2.7". I need to paste an image from other
application using "Java version 1.4.1". I am trying to retrieve the image
from the system clipboard after it is copied from some other application. I
am pasting the code which illustrates my requirement. It works fine on
windows. But does not work on Mac.
On Mac it does not cross the supported data flavor check
(clipData.isDataFlavorSupported(DataFlavor.imageFlavor) where clipData is
the Transferable object). It seems Mac has some InputStream instead of Image
in the clipboard when some image is copied. I tried to read that InputStream
using ImageIO.read(java.io.InputStream). But that is also returning null.
Thanks

Using system clipboard w/ java

Does anyone know how java can input a string into the system clipboard that can be accessed later?

public void Copyit() {
      try{
      getit = area.getSelectedText();
      c = Toolkit.getDefaultToolkit().getSystemClipboard();
       Transferable contents = clipboard.getContents( im );
           c.setContents( contents, null );
          if(getit.equalsIgnoreCase("null")){ throw null; }
       }catch(NullPointerException nul){ System.out.print("Clipboard is emty");}
public void Pasteit() {
          c = Toolkit.getDefaultToolkit().getSystemClipboard();
          Transferable contents = c.getContents(this);
          String getit1 = "";
          try {
            getit1 = ( String ) contents.getTransferData( DataFlavor.stringFlavor );
        if(getit.equalsIgnoreCase("null")) { getit = null;
           throw null; }
           else
            field.setText(getit1);
         }catch(NullPointerException e ) {
           System.out.println( "Unable to read system clipboard" ); }    catch(Exception ee ) {
           System.out.println( "Unable to read system clipboard" ); }
}here is two function that will work on a textfild/textarea you just have to piece the rest together which is not much or hard

Using clipboard with java

Is there a way to take a string and input in into a field on a seperate program? (Such as input a string into an open file box in notepad. Notepad is already open and the open window is already open.)

Sending key presses is pretty simple, i was wondering if there was a way to use the system clipboard, then just use the ctrl+V keypress, rather than converting the entire string to keypresses, cause that takes more processing time as far as i can tell

Detect something just copied to the clipboard

Hi everyone,
I'm wondering if it is possible for a java program to detect something just got copied into the system's clipboard? I don't mind using JNI if that helps. I need to be notified after a user "right click and select copy" in any application. They can be copying something in microsoft word and i want to be notified in my java program when a copy-to-clipboard is just made. Is this even possible in Java? I searched the forumn and didn't see any topic on this. TIA

Run this program, it is an example of monitoring the clipboard.
import java.awt.*;
import java.awt.datatransfer.*;
class MyClipboardOwner implements ClipboardOwner {
    public void lostOwnership(Clipboard clipboard, Transferable contents) {
        System.out.println ("Someone copied something to the clipboard");
        DataFlavor[] df = contents.getTransferDataFlavors();
        for (int i = 0; i < df.length; ++i) {
            System.out.println (df);
public class Test105 {
public static void main(String[] args) throws Exception {
Clipboard cb = Toolkit.getDefaultToolkit().getSystemClipboard();
cb.setContents(new StringSelection ("Put this in the clipboard"), new MyClipboardOwner());

Native -- DataFlavor clipboard problem

I'm trying to access vim specific clipboard data (to get visual block info). This is on windows XP (unix is next) I've registered the formats with addFlavorForUnencodedNative, see java code below. But when I look at all the clipboard flavors, when clipboard contains vim stuff, no vim flavors show up, see output.
Any ideas of what/where the problem might be?
Thanks,

In vim, from its os_win32.c, there is
    clip_star.format = RegisterClipboardFormat("VimClipboard2");
    clip_star.format_raw = RegisterClipboardFormat("VimRawBytes");and when a vim copy to clipboard command is issued, in vim's os_mswin.c. Note that cbd->format is clip_start.format, returned from RegisterClipboardFormat above.
SetClipboardData(cbd->format, hMemVim);
SetClipboardData(CF_UNICODETEXT, hMemW) != NULL)
SetClipboardData(CF_TEXT, hMem);When I run the java program I get the following output. First are the mimetype of the 3 native flavors I added; in cb.getAvailableDataFlavors() none of them appear in the 27 flavors available.
VimClipboard application/vimclipboard; class=java.nio.ByteBuffer
VimClipboard2 application/vimclipboard2; class=java.nio.ByteBuffer

Writing on system clipboard from an applet.

Is it possible?
I have tried to write on it but an exception is occoured:
java.security.AccessControlException: access denied (java.awt.AWTPermission accessClipboard)
The code that I have used is:
import java.security.*;
import java.awt.*;
import java.awt.datatransfer.*;
import javax.swing.*;
public class Blah extends JApplet {
public void init() {
String exampleStr = "Hi!";
Clipboard clipboard;
Transferable trans;
StringSelection strSelect;
try {
SecurityManager security = System.getSecurityManager();
if (security != null)
security.checkSystemClipboardAccess();
clipboard=Toolkit.getDefaultToolkit().getSystemClipboard();
strSelect = new StringSelection(exampleStr);
trans = (Transferable)strSelect;
clipboard.setContents(trans, strSelect);
System.out.println("Clipboard copy successful");
catch (Exception e) {

System.err.println(e);
Thanks

First, your applet must be signed to access the system clipboard. And on Netscape 4.7.x, you need to enable the privilege from within the same method where you get the system clipboard. On IE 5.5/6.0, signing the applet is all that is necessary.
Here's what I do on Netscape:
Make sure when you call "PrivilegeManager.enablePrivilege("UniversalSystemClipboardAccess");", that you get the system clipboard within the same method. Failure to do this will cause a ForbiddenTargetException.
My code looks like:
public java.awt.datatransfer.Clipboard getSystemClipboard()
java.awt.datatransfer.Clipboard clipboard = null;
try
PrivilegeManager.enablePrivilege("UniversalSystemClipboardAccess");
clipboard = java.awt.Toolkit.getDefaultToolkit().getSystemClipboard();
PrivilegeManager.revertPrivilege("UniversalSystemClipboardAccess");
catch (netscape.security.ForbiddenTargetException se)
se.printStackTrace();
catch(Exception e)
e.printStackTrace();
return clipboard;
This works successfully on Netscape 4.7.8. On IE 5.5/6.0, I didn't have to do anything other than having a signed applet to get the system clipboard. With the code above, I also am using a signed applet.
Hope this helps anyone else trying to make this work.

I am using JDK 1.3 and JDK 1.4 and I've got the following question:
If I use the javax.swing.JTextPane object, I can define a javax.swing.text.DefaultEditorKit and other actions in order to implement copy/paste functionality. My question is: Which clipboard is used here? The java api documentation of javax.swing.text.DefaultEditorKit.PasteAction states that the system clipboard is used.
But this particular applet I am using is not permitted to use the system clipboard, I cannot get the system clipboard from java.awt.Toolkit, it throws an exception.
The reason for me writing the question into that forum is that I want to manually access the clipboard that is used by my JTextPane object.
Ciao

Copying drawing objects from MS word to clipboard

Hi all,
Is there any way to copy anything from ms-word and store it in the file and retreive that back from file and paste it back to ms-word ?
I have a applet that is able to copy string and image data independently from clipboard to java and vise versa. I am not able to do the same with organization chart or any mixture of string and image data. I am not even sure about the DataFlavor to use. Can some one please suggest any possible solution ?
I tried with "image/x-java-image;class=java.awt.Image" and
"text/rtf; class=java.io.InputStream". but unable to get any result from clipboard.
My requirement is to store some charts from ms-word to java and later on retrieve them back to java into ms-word and make modification in the chart.
Thanks in advance,
Sid

Any idea on this .................... Pleeeeease :-(

Copy cannot be disabled to my knowledge. Did you try quitting Safari and resetting your iPad? To quit an app double click the Home button to reveal the row of recently used apps. Flick up on the page preview and it will fly away and disappear. That quits the app. Then Press and hold both the Home button and the Sleep/Wake button continuously until the Apple logo appears. Then release the button and let the device restart. You will not lose data doing this. It's like a computer reboot.

Copy paste from windows clipboard to JTextField

I am making a swing application with a lot of components in it. There are a lot of JtextFields in the application. when i do Ctrl+C from a JTextField and do a Ctrl V in a different JTextField of the same application the text gets copied to the second JTextField. But when i copy something from windows and try to paste it in JTextField it does'nt work. Please guide me. Some other component is eating up the Ctrl C/Ctrl V event or what?
I tried adding keystroke's to the InputMap of the JTextField but it still does'nt work.
Kindly guide me. Thanks in advance
Excerpts from the code:
JTextField text1 = new JTextField();
KeyStroke copykeystroke = KeyStroke.getKeyStroke(KeyEvent.VK_C, InputEvent.CTRL_MASK);
KeyStroke pastekeystroke = KeyStroke.getKeyStroke(KeyEvent.VK_V, InputEvent.CTRL_MASK);
text1.getInputMap().put(copykeystroke, "copy-to-clipboard");
text1.getInputMap().put(pastekeystroke, "paste-from-clipboard");

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import javax.swing.text.*;
public class CutCopyPaste {
public static void main(String[] args) {
    Action cut = new TextAction("cut") {
      public void actionPerformed(ActionEvent e) {
        getFocusedComponent().cut();
    Action copy = new TextAction("copy") {
      public void actionPerformed(ActionEvent e) {
        getFocusedComponent().copy();
    Action paste = new TextAction("paste") {
      public void actionPerformed(ActionEvent e) {
        getFocusedComponent().paste();
    JMenu menu = new JMenu("edit");
    menu.add(cut);
    menu.add(copy);
    menu.add(paste);
    JMenuBar menuBar = new JMenuBar();
    menuBar.add(menu);
    JTextField textField = new JTextField(15);
    JPanel northPanel = new JPanel();
    northPanel.add(textField);
    JTextArea textArea = new JTextArea(5,25);
    textArea.setLineWrap(true);
    textArea.setWrapStyleWord(true);
    textArea.setMargin(new Insets(5,10,5,10));
    JPanel panel = new JPanel();
    panel.add(new JScrollPane(textArea));
    JFrame f = new JFrame("Cut Copy Paste");
    f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    f.setJMenuBar(menuBar);
    f.getContentPane().add(northPanel, "North");
    f.getContentPane().add(panel);
    f.setSize(400,180);
    f.setLocation(400,300);
