Hi,
long time ago I posted a patch that allows one to resize a column in a
gtkclììÿ¿6Ê
ist
to the optimal width by double clicking the resize window.
Since I find that this a useful feature and that there was no answer I will
repost the patch. It is fully outdated right now. I do not have a lot time
left
playing with my linux box. So someone with more deep gtk+ knowledge could
reimplement the feature?
Thanks Dirk
