Overview

These macros must be used when describing a class.

A class description is an array of GB_DESC structure, whose each element is filled with one of the following macros.

The first element must be filled with the GB_DECLARE macro, and the last one must be filled with the GB_END_DECLARE macro.

The following macros must be used at the beginning of the array, just after GB_END_DECLARE:

• GB_AUTO_CREATABLE

• GB_INHERITS

• GB_NOT_CREATABLE

• GB_VIRTUAL_CLASS

The other macros can be used in any order, as the interpreter will sort them anyway.

Here is the declaration of the Window class:
