Ok, I'll try to explain what I want to do, so you can tell me if I'm doing it the way is supposed to be done.
As you said, I want to modify how widgets are drawn (by using cairo inside the style virtual functions), and I have no intention of creating a new complete theme engine. If all applications should share the same look is a point of view quite extended , but what I want to do is just the opposite (define my own look and feel in my application) I'm trying to do it just the way you mentioned, by calling set_style in the affected widgets. But if we recover the example code, I'm getting some pango errors and a segfault when trying to use an overloaded Gtk::Style in a label widget (other widgets I have tested works fine with this approach). I've been looking to the Gtk::Style code in style.cc and the create() function does nothing but create the Glib::RefPtr, so I'm quite confused write now. ¿what can it be wrong?
