Nice work Chris! I am now working on this same feature for Win32 and for
Linux. I plan to submit my patches back to eclipse.org, perhaps with
your work on Mac these features are getting closer to full
cross-platform and therefore candidate for official release

Hi Mike,
I've submitted the changes I had to make for Mac OSX to bug 22035. I
didn't have to write a Callback because I just had to enable a setting
on a Shell (ie. Window).
Also, I had submitted some code for win32 and was looking at GTK. There
seems to be a method 'gtk_tree_view_column_set_reorderable' that enables
a column to be reordered. I don't have Linux desktop box to test this
out but this might help you.
There are only two other platforms left : Motif and Qnx (Photon)
If you already finished implementing this feature for Win32 and Linux
then feel free to send me an email or reply how you did it.
Thanks,
Chris Nagy
