Thank you for replying. However, for me the above has no visible effect. 
Now I understand that a GtkStyle is just about colors and similar 
settings, which only partly determine the looks of a widget. In my case 
I suspect that a GtkTreeView.GtkButton has the same GtkStyle settings as 
ordinary buttons, which is why I see no change.

What I want is that a button of my choice is rendered exactly like the 
title button in a treeview. I rephrased the subject accordingly.

I recently discovered that there is something called a theme engine, and 
I guess I need to trick the theme engine into thinking that it is 
drawing a GtkTreeView button. Is there a way to do that? If the method 
would be engine-dependent, I need it to work on MS Windows.


Thanks,
Bastiaan.
