Subject: GtkTreeView sorting question


Hi!
I wonder why my column in GtkTreeView isn't sorted just after
starting application. Looks like I missed something. When
I click on header it sets sorting order ascending/descending
and then sorts rows. But not before.

I apply here test program. After starting rows are in order:
Z
C
B
D
A

But sort order is set to ascending and this sorting happens when
I click on header once:
A
B
C
D
Z
