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