\file MacroMagic.h
This file allows the same macros to do multiple duty by undefining
and redefining the macros.
For example DEFINE_IMAGE will generate:
- extern int name;
- int name = -1;
- RegisterImage( allNames, myFlags, name, initialiser, textual_name);
On three different passes. We control which by defining one of
THEME_INITS or THEME_DECLARATIONS or neither of these.
*//*******************************************************************/
using teBmps = int; /// The index of a bitmap resource in Theme Resources.
// undefine the macros.
#undef DEFINE_IMAGE
#undef DEFINE_COLOUR
#undef SET_THEME_FLAGS
#define THEME_EXTERNS
#ifdef THEME_INITS
#define DEFINE_IMAGE( name, initialiser, textual_name ) \
theTheme.RegisterImage( allNames, myFlags, name, initialiser, textual_name );
#define DEFINE_COLOUR( name, initialiser, textual_name )\
theTheme.RegisterColour( allNames, name, initialiser, textual_name );
#define SET_THEME_FLAGS( flags ) ( myFlags = flags );
#undef THEME_DECLARATIONS
#undef THEME_EXTERNS
#endif
#ifdef THEME_DECLARATIONS
#define DEFINE_IMAGE( name, initialiser, textual_name ) THEME_API teBmps name=-1;
#define DEFINE_COLOUR( name, initialiser, textual_name ) THEME_API int name=-1;
#define SET_THEME_FLAGS( flags )
#undef THEME_INITS
#undef THEME_EXTERNS
#endif
#ifdef THEME_EXTERNS
#define DEFINE_IMAGE( name, initialiser, textual_name ) extern THEME_API teBmps name;
#define DEFINE_COLOUR( name, initialiser, textual_name ) extern THEME_API int name;
#define SET_THEME_FLAGS( flags )
