While I don't have a snippet or example I can post, I can say we have
done this using both FileTransfer and ByteArrayTransfer so it is possible.

I'm delighted that it's possible... If you can offer any crumbs of advice
that would be wonderful because it seems that our project, and perhaps a
few other perople's projects, are languishing with the lack of support.
We are dying here...

I'm stuck on this too! If anyone has any information about how to resolve
the incompatibility between custom SWT ByteArrayTransfer and custom Swing
DataFlavors, please help us out? My am required to provide a solution to
this very soon and unfortunately I'm also stuck! It's just so tricky to
debug because it either all works or it doesn't... I just keep getting
java.awt.datatransfer.UnsupportedFlavorException also.

Does anyone have a code snippet on how to do this, or know how to declare
a DataFlavor to be compatible with a custom SWT ByteArrayTransfer type? It
sounds like this is causing more than a few people some grief.

Help, please, anyone!

Chris.

hi,
Even i am working on this issue. I tried the example given here
http://dev.eclipse.org/viewcvs/index.cgi/org.eclipse.swt.sni ppets/src/org/eclipse/swt/snippets/Snippet319.java?view=co

It works well on the windows platform, but doesn't work on Mac OSX 10.6.
Even tried using JRE 1.6. I am using Eclipse SDK 3.5 macosx-cocoa-x86_64.

Thank you,
Rohit

On Cocoa I don't even see the JLabel there. I've logged
https://bugs.eclipse.org/bugs/show_bug.cgi?id=289612 for this.

Do you have a case on Cocoa where the AWT/Swing control is visible but the
drag and drop is still not working?

Grant

hi Grant,
yeah the Label was not visible earlier. I used frame.pack()
and the label showed up. Even with the label showing DND does not work.
