Assignment Operator in GtkWidget

[jalkadir gosonic ca]

 In the constructor I assigned values to the two variables,
namespace jme{
class Data{
   public:
      std::string str;
      GtkWidget* obj;
   public:
      Data(){str = ""; obj = gtk_window_new(GTK_WINDOW_TOPLEVEL);}
      void setStr(std::string ps){ str = ps;}
      void setObj(GtkWidget* o){obj = o;}
  };
}
and as soon as I get the value for the jme::Data::str variable, I replace
the value, but for jme::Data::obj, I replace the value as soon as the
GtkWidget::MainMenuWin value is aquired.

But, for some reason, I am unable to use the assignment operator on
GtkWidget objects.

What should I do now?




The code is here:
namespace jme{
class Data{
   public:
      std::string str;
      GtkWidget* obj;
   public:
      Data(){str = ""; obj = gtk_window_new(GTK_WINDOW_TOPLEVEL);}
      void setStr(std::string ps){ str = ps;}
      void setObj(GtkWidget* o){obj = o;}
  };
}
//Declare the objects
GtkWidget* MainMenueWin;
GtkWidget* VBx;
GtkWidget* Label;
GtkWidget* Separator;
GtkWidget* btnExit;
GtkWidget* btnCreateAccount;
GtkWidget* btn2;
GtkWidget* btn3;
GtkWidget* btn4;
GtkWidget* btn5;
jme::Data* data;
std::string msg("Under Comstruction ... I am very sorry, but this \
