Re: [Vala] How to change the widget color

[Flavio Danesse <fdanesse gmail com>]

    var screen = Gdk.Screen.get_default();
    var css_provider = new Gtk.CssProvider();
    string style_path = "Estilo.css";
    css_provider.load_from_path(style_path);
    Gtk.StyleContext.add_provider_for_screen(
        screen, css_provider,
        Gtk.STYLE_PROVIDER_PRIORITY_USER);


If you want you can review the code of my player:

Incidentally, I accept tips to improve it, I come from python so surely my
vala code can be substantially improved.
