- Desc: Header file for ScrollGroup and ScrollDialog classes.
-
- This file is the header file for a pair of classes that allow use of a
- scroll-able dialog box. It is designed for (but doesn't require) a TV.H-like
- master header file with the following lines:
-
- ...
-
- #ifdef Uses_ScrollDialog
- #define Uses_TDialog
- #define INC_DLG_H
- #endif
-
- #ifdef Uses_ScrollGroup
- #define Uses_TGroup
- #define INC_DLG_H
- #endif
-
- ...
-
- #include <tv.h>
-
- ...
-
- #ifdef INC_DLG_H
- #include "Dlg.h"
- #endif
-
- ...
