Changing the GtkTreeView Bar Color....

[Glus Xof <gtglus gmail com>]

Hi guys,

I'm looking for the CSS sentence to change the GtkTreeView Bar Color... I mean the selection bar that is set like blue in Adwaita default theme (in gtk+-3.0 style).

I tested unsuccesfully with

GtkTreeView :selected {background-color: #...}

But I don't see any reference documentation for that...

Any idea ?
