Python: Changing the select colour in a GtkTreeview

I want to disable the selection colour at a treeview. So I want to set the selected color to white with modify_base. I found this solution, but it doesn't work. This is my code:

import gi
from gi.repository import Gdk, Gtk
gi.require_version('Gtk', '3.0')

treestore = InterfaceTreeStore()
treeview = Gtk.TreeView()
treeview.set_model(treestore)

treeview.modify_base(Gtk.StateFlags.SELECTED, Gdk.Color(red=65535, blue=65535, green=65535))

gtk_widget_modify_base has been deprecated since 3.0. You could have used gtk_widget_override_background_color, if it wasn't deprecated since 3.16. It's documentation states that:

If you wish to change the way a widget renders its background you should use a custom CSS style

However, if you want to disable selection color, the simpliest way is to unselect.

Your "changed" signal callback might look something like this:

def changed_cb(selection):
    model, iter = get_selected (selection)
    # if there is no selection, iter is None
    if iter is None:
        return
    # do something useful
    # now unselect
    path = model.get_path(iter)
    selection.unselect_path(path)
    path.free() # not sure if python frees it automatically
