See the GObject Developer Docs.
See creating a Gobject for an example on deriving objects.
GObject is implemented in Glib and builds Objects in run-time (unlike C++ and many other object oriented languages which do this at compile tim).
- similar to C++, using vtables.
- explicit upcasting and downcasting.
- Capable of meeting the three tenets of OOP. (See The Wikipedia Article).
create a person that says "hi my name is xxx". when person::talk is implemented
create an example dr_phil that inherits from person and says "And hows that working for you?" when person::talk is called.
this should provide us with deriving a first object, which is a pain to learn. and how inheritance works in Glib.
What needs to be explainedEdit
- type check and type cast macros
- the purpose of get type
- the order in which objects are instantiated
- creating object
- construct and desctructor methods
- the difference between class and instance
- virtual functions
