Animates statusbar icon

[Camilo Martin Culpian <camiloculpian gmail com>]

I like to create an animated statusbar icon like this:

void animate_statusbar_icon(Glib::RefPtr< Gtk::StatusIcon > icon)
{
    while (true)
    {
        icon->set_from_file("icon.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_2.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_3.png");
        sleep(1);
        icon->set_from_file("icon_4.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_5.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_6.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_7.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_8.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_9.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_10.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_11.png");
        icon->set_visible();
        sleep(1);
        icon->set_from_file("icon_12.png");
