While I'm finding possible API problems...is gtk_style_attach() wrapped
anywhere? I cannot find it either under Gtk::Style or Gdk::Window and,
resultingly, I don't believe that copy()'d styles can be used without
dropping back to GTK+.
For example, this is the only way I can see to create a derivative style
with a specific background colour (assume that it's during a Gtk::Widget
subclass' on_realize()):
m_orange = get_style()->copy();
m_orange->set_bg(Gtk::STATE_NORMAL, Gdk::Color("#ffaa00"));
m_orange = Glib::wrap(
gtk_style_attach(
m_orange->gobj(),
m_gdk_window->gobj()));
Attempting to use this style without the attachment results in a
Gdk-CRITICAL, as it hasn't been realized (and thus allocated colours and
such) yet. Likewise, detach() appears to be missing, which I believe is
required for cleanup.
