## 2.3 The EZwgl Header File

The one and only header file `EZ.h` must be included in all source files of an EZwgl applications with the following include directive:

    #include "EZ.h"

This files contains definitions needed by all applications. Currently, this file only contains the forward declarations, symbolic constants and a few type definitions. The internal widget data structures are hidden from this header file. This situation may be changed in the future.
