Should be sure it's in bugzilla.

No, it doesn't have that feature.

the target is, different typ of row to mark, z.b. red for total, green
for subtotal and so on. And the second goal is to mark record whith
certain semantics.

Yes 2.0 on alpha - 64 bit - offen a problem.

when the the record to show is very large, you can scroll to the rigth
und the first column with the key is not scrolling, it named 'vertical
title'. Is such a feature in GtkTreeView.

Hi,

I use it also. It is very useful for all purposes ;)
It is definietly nice to have it for database applications.
For example: you have database of equipment:
working ok - green,
not working properly - yellow
damaged - red,
in factory repair - blue
etc.

It will be pain to do it on per cell basis.
So please add it to bugzilla.

Regards,

Olaf Fraczyk

I don't think there is one. What's the application?

You probably have to change the color of each cell separately by
setting properties on the cell renderer or writing a custom cell
renderer.

You can create alternating colors with gtk_tree_view_set_rules_hint().

Looks like a divide-by-zero in gtkrange.c. This is in 2.0.0?

Indeed, it looks like the function is broken. Can you report this on
http://bugzilla.gnome.org.

You can put the tree-row-color feature request there too, but should
explain your use-case for the feature to aid in deciding on an API.

set attributes to rows in GtkTreeView

[Bernd Demian]

Hi all,
thanks for the gtk-version, great job

btw I have one question, one bug and one suspicion.

First the question: Can somebody show me a simple way to change the
color of one or more rows in GtkTreeView. In CList it was simple to use
the function gtk_clist_set_background. 

Second the bug : I have gtk+ installed on True64 and in the testgtk appl
it crased when I select the text.
Here is the stack from core file. I hope somebody can find the bug.
