Hi, I'm studying GObject system and found that I can implement both Pure Virtual Class (by setting all member functions NULL to make the class pure virtual) and an Interface in GObject.
I'm a C programmer without much C++ experiences, but according to my understanding ... pure virtual class in C++ is Interface. Am I correct ? My guess is, in GObject, provide extra API to implement an Interface is just another easier way to implement pure virtual class. GObject interface will add more internal check which is better than just set the member function to NULL, but ... there are the same stuff, am I correct ? Does any other good reason why GObject need an extra API set for Interface ? What's the different between Pure Virtual Class and Interface in GObject system ? Regards KC
