Bug 97087

Can you please add missing style classes to pavu-control for gtk+-3.20?
1. one at top level, eg. pavu-control, in result i can use
window.background.pavu-control > box.vertical > notebook {
}
for styling the notebook and others.
2. Adding the style class .frame to the notebook, because most preferences windows use notebook.frame {}.
So pavu-control will use the same styling from themes without writing extra code for it.

Curently i need to use a ugly hack for making pavu-control nice.

window.background > box.vertical > notebook {
}

The problem is that GtkNotebook is everywhere in application code, so with such a setting i match also other application, eg. virt-manager, mate-terminal, gnome-terminal and others, and i have to override the settings for pavu-control again.

So adding those 2 style classes will make my live easier, and users will have a nice linux experience with gtk+-3.20.

Note, also other gnome applications like nautilus have added such a top selector for gtk+-3.20

Thank you

Could you either provide a patch, or provide an example of what needs to be done?

I think it should be done the same way as shown here:
https://github.com/mate-desktop/caja/blob/master/src/caja-desktop-window.c#L57

#if GTK_CHECK_VERSION(3, 0, 0)
    GtkStyleContext *context;

    context = gtk_widget_get_style_context (GTK_WIDGET (window));
    gtk_style_context_add_class (context, "caja-desktop-window");
#endif
