#370 Clipborad Problem RDesktop <-> Java

[Ruedi Steinmann]

I use rdesktop under Linux to connect to a Windows machine. When using rdesktop with -5 -r clipboard:PRIMARYCLIPBOARD, copy/paste does not work from Java/Swing programs on the Linux machine to applications on the remote windows machine.

I tracked the problem down and found that

• the java program does not provide the TIMESTAMP content type
• rdesktop uses the TIMESTAMP to choose between the PRIMARY and the CLIPBOARD selection. (in xclip.c)

(rdesktop 1.7, Java 1.6)

Below is a small Java program for reproducing the bug:

import java.awt.Toolkit;
import java.awt.datatransfer.StringSelection;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

import javax.swing.JButton;
import javax.swing.JFrame;

public class Main2 {
    public static void main(String[] args) {
        JFrame frame=new JFrame("Clipboard Test");
        JButton button=new JButton("Paste");
        frame.add(button);
        button.addActionListener(new ActionListener() {

            @Override
            public void actionPerformed(ActionEvent e) {
                StringSelection selection=new StringSelection("foo");
                Toolkit.getDefaultToolkit().getSystemClipboard().setContents(selection, selection);
            }
        });
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.setSize(200, 200);
        frame.setVisible(true);
    }
}
