GtkTreeView with resizeable Columns

[Guenther Wutz <admin wutzara de>]

Hi list,

i have a problem with GtkTreeViews in Gtk+-3.0. I want a behaviour like
this: http://i.imgur.com/vAaHk.png

My problem is, that this is not the default setting for GtkTreeViews. I
already made an Test-Case for this: http://pastebin.com/wxvNAyUa

The commented Code was only a test, but it wont work like expected. My
second attempt to find a solution was a ScrollWindow on top of all
Widgets (a tip from #gtk+): http://pastebin.com/mttXaqFh . Now i got the
expected behaviour but without resized Cells. The Cell-height is
constant. Is there a way how i can archive all this with modified
Cell-heights?

Regards,
