GtkStyle to the widget's
GdkWindow. It is a replacement forgtkWidgetStyleAttach(object)objectwidget->style = gtk_style_attach (widget->style, widget->window);and should only ever be called in a derived widget's "realize" implementation which does not chain up to its parent class' "realize" implementation, because one of the parent classes (finally
GtkWidget) would attach the style itself.
