RTFEditorKit vs. clipboard: formats

Thread view:

Hi folks,

I'm using an RTFEditorKit in a JTextPane. I'd like to copy the RTF
text from the text pane to the (Windows) clipboard, but calling
JTextPane's copy() method only copies plain text. If I use an
HTMLEditorKit, the same call gives me HTML on the clipboard, so I think
my code's doing what it should.

Is this a bug in the RTFEditorKit? Will it ever be fixed?

If it is a bug, how do I go about fixing it? I gather I need to
implement a new TransferHandler, but I don't know how to do that or
where to go for more information.

Thanks!

Fred

Probably, I don't know for sure. I know that the Styled document doesn't
implement a proper way to get styled text back, so this might be the
root of your problem. See

for a related discussion.

Also, check Sun's bug parade to find out if this is a known bug.

Most likely not. RTF (and HTML) editing don't have any attention from Sun.

You could try to work around it by drilling down to the document, and
trying to write some own extraction method for the current selection.
You could then try to manually copy that DataFlavor to the clipboard
(see the java.awt.datatransfer package) or via a custom TransferHandler.

TransferHandler is just a front end to the java.awt.datatransfer
package. Have a look at the documentation for that package to understand
the basics. Then check
