Hi Duncan-
I can't quite get your modifications to make Steve's app work, but
that's not important. It's not really difficult to paste _inside_ a
Java application. I think what Steve Zara was doing was highlighting
text in some (say,) non-Java application, and thus then pasting that to
the Java app from the system clipboard. In that case one receives the
"X11Selection" error I discussed in my previous post, which I discovered
debugging a problem with a CoreJava example.
Say I highlight a couple of words in your e-mail and then use the paste
button in Steve's java application (with your mods), then I get:
-----
Exception occurred during event dispatching:
java.lang.NullPointerException:
at
sun.awt.motif.X11Selection.isDataFlavorSupported(X11Selection.java:223)
at clipboard$2.actionPerformed(clipboard.java:53)
at java.awt.Button.processActionEvent(Button.java:257)
at java.awt.Button.processEvent(Button.java:230)
at java.awt.Component.dispatchEventImpl(Component.java:1781)
at java.awt.Component.dispatchEvent(Component.java:1708)
at java.awt.EventDispatchThread.run(EventDispatchThread.java:81)
----
i.e., more or less what Steve was getting.
Whereas, if one makes the change to (gutting of!) his button method as I
mentioned:
-----
...
b2.addActionListener( new ActionListener() {
public void actionPerformed(ActionEvent e)
{
Transferable data=Clip.getContents(this);
//System.out.println("data is: "+data);
String result = "";
try {
result =
(String)data.getTransferData(DataFlavor.stringFlavor);
}
catch (Exception ex) {;}
t2.setText (result);
t1.setText (result);
}
});
...
-------
a paste of some non-Java stuff works (shows up in both areas.)
Matters are a bit confused here, IMO because there's not a lot of
agreement on what's being attempted. ;-)
FWIW.
