Re: [platform-swt-dev] TreeColumn Labels have to be the same size?

I must be missing something. The snippet
below produces the following snap on Windows XP.
Is this not what you meant?

This is a Microsoft Windows limitation.

I believe this is an underlying table limitation.  I have run into
problems with images in tables before.  It seems that the first image
you set is the the width your stuck with, as far as I can remember :-)
 
Maybe it's been fixed/changed in more recent swt updates??
