Assignment operator for GtkWidgets?

Is there such a thing, can we do things like MyGtkWidget = SomeGtkWidget?

I get a segmentation fault when I try todo that!


What am I doing wrong?

   public:
      std::string str;
      GtkWidget* obj;
   public:
      Data(){str = "";}
      void setStr(std::string ps){ str = ps;}
      void setObj(GtkWidget* o){obj = o;}
};
