gl function,how to???

OpenGL OpenGL: Basic Coding

i have a quick question,

does anybody know if we can use this function like that?

glutDisplayFunc(display); instead

glutDisplayFunc(aClass.display());

(aClass is a class :))is usage above legal?

2

It is if display() is a static method in C++.

(To be more precise I should probably say that it’s legal if aClass.display() evaluates to a pointer to static method.)

3

The reason you can’t do that and need to use a static is non-static methods have a ‘this’ parameter i.e. the object this method is being called on. If you are wanting to wrap stuff in a class have a look at this thread.
