I think it's Widget::on_size_request().

There is a member function inherited from widget, modify_bg(). I have
the following somewhere in my Hardware Monitor code:
void CanvasView::do_set_background(unsigned int color)
{
Gdk::Color c;
c.set_rgb(((color >> 24) & 0xff) * 256,
((color >> 16) & 0xff) * 256,
((color >> 8) & 0xff) * 256);
canvas->modify_bg(Gtk::STATE_NORMAL, c);
canvas->modify_bg(Gtk::STATE_ACTIVE, c);
canvas->modify_bg(Gtk::STATE_PRELIGHT, c);
canvas->modify_bg(Gtk::STATE_SELECTED, c);
canvas->modify_bg(Gtk::STATE_INSENSITIVE, c);
}

Hm, you probably have to code it yourself. Four lines with rounded
edges.
