I do not know how to override the theme, but you can set any color you
want using a custom cell renderer.

Re: [pygtk] pygtk tree view expanders custom color
Hi and thanks for reply, I already control the background and foreground of
the cells,
what I cannot control is the color of the expander arrows (the ones that
when clicked show/hide the children rows)

You can change it like any other part or widget in GTK3. Just add the
following to your stylesheet:
.expander {
color: rgb(32, 74, 135);
}
Or be more precise about which treeview and do:
GtkTreeView#MyCustomView .expander {
color: rgb(32, 74, 135);
}
And in your code:
treeview.set_name(MyCustomView)

Timo

Re: [pygtk] pygtk tree view expanders custom color
Hello Timo,
thank you very much for the reply,
unfortunately I cannot upgrade to GTK3 because my app (
http://www.giuspen.com/cherrytree/)
has to fully work on microsoft windows and I see that pyGI or whatever is
the name of python-GTK3
still doesn't work on windows.
It's sad to say but if GTK people will not spend time to support
cross-platform rather than just adding functionalities
more and more people will leave it for Qt and python-Qt.
Cheers,
Giuseppe.

I completely agree Giuseppe. My cross-platform applications also still
use GTK2 for that same reason.
For a Linux only project I'm using GTK3 and I really like it (like the
CSS theming for example), but I would probably think twice again in the
future when starting a new large project. Which is a real shame if you
look at how awesome GTK is.
I can't help you with GTK2 theming though, sorry.
Timo
Cheers,
Giuseppe.

I'm also using GTK (mm) 3 in a linux only project but at my company we're dropping GTK (that I personally introduced) because we absolutely need to reuse the code in other cross platform projects. GTK3 is like a beautiful car that performs great when it's sunny but cannot travel when it's rainy, only good for people that can afford two cars.
