Jacek,
In Gtk it is not common to alter the row color as it is controlled by
the currently installed theme. I have had minor success with altering
the appearance of widgets without changing the theme but it has been a
frustrating task to say the least. I'm sorry I don't have a solution
that is useful enough to pass on but I thought you may want to know that
it is not common to go against the theme so it can be aggravating. But I
will say your on the right path, try browsing Banshee's source code they
have done quite a bit with TreeViews.
I hope this is at least a little helpful.

Hi folks,
I am fighting with a not-so-strange wish: I have a TreeView with a TreeStore
behind it, and now I wanna give a newly-inserted row (!!) a different
color...for instance, white letters on red background. For another TreeView
with ListStore, this code already works fine:
private void MarkErrorRow (int row)
{
foreach (TreeViewColumn column in
this.itemTreeView.Columns) {
CellRendererText cell = (CellRendererText)
column.CellRenderers [row];
cell.ForegroundGdk = new Color((byte) 0xFF,
(byte) 0xFF, (byte) 0xFF);
cell.BackgroundGdk = new Color((byte) 0xFF,
(byte) 0x00, (byte) 0x00);
}
}
But when I try to use the same code in conjunction with a TreeStore, I always
get a crash 'cause the CellRenderers array only contains one single item.
Even worse: I really use the "tree" functionality of the TreeStore, and
sometimes I have to "paint" child rows, too.
Any suggestions?
Regards
Jacek
