don's class application library: d clap lib

putting NCBI Tools & NCBI Vibrant -- cross-platform toolkit -- 
into a C++ class application library, roughly patterned on MacApp, Think CL, ...

Vibrant notes:
	see vibwndws.c for main(), Nlm_ProcessEvents()
		-- mac & mswin break anyevent into event classes: mouse, key, command(?),...
		-- xwin anyevent breakdown NOT FOUND!?
	see vibutils.c for Nlm_DoClick(), Nlm_DoCommand() == task kind handlers, specific to each win system!
		-- mac:   DoClick(), DoKey(), DoDraw()==update, DoIdle()
		-- mswin: DoCommand()
		-- xwin:  DoCallback()
		
	change vibrant, to map from static proc callbacks to object handlers:
vibincld.h:
	typedef  struct  Nlm_graphicrec {
  Nlm_GraphiC   next;
  Nlm_GraphiC   parent;
  Nlm_GraphiC   children;
  Nlm_GraphiC   lastChild;
  Nlm_GphPrcs   PNTR classptr;
  Nlm_ActnProc  action;
  Nlm_RecT      rect;
  Nlm_Boolean   enabled;
  Nlm_Boolean   visible;
#ifndef NOCLAP
	Nlm_VoidPtr 	thisobject; /* <<<add to hold DObjectPtr */
#endif
} Nlm_GraphicRec, Nlm_GraphicData, PNTR Nlm_GphPtr;


vibprocs.h:
#ifndef NOCLAP
void Nlm_SetObject PROTO((Nlm_GraphiC a, Nlm_VoidPtr thisobject));
Nlm_VoidPtr Nlm_GetObject PROTO((Nlm_GraphiC a));
#endif

vibutils.c:
#ifndef NOCLAP
extern void Nlm_SetObject (Nlm_GraphiC a, Nlm_VoidPtr thisobject)
{
  Nlm_GraphicData  gdata;
  if (a != NULL && thisobject != NULL) {
    Nlm_GetGraphicData (a, &gdata);
    gdata.thisobject = thisobject;
    Nlm_SetGraphicData (a, &gdata);
  	}
}

extern Nlm_VoidPtr Nlm_GetObject (Nlm_GraphiC a)
{
  Nlm_GraphicData  gdata;
  if (a != NULL) {
    Nlm_GetGraphicData (a, &gdata);
    return gdata.thisobject;
  	}
	else return NULL;
}
#endif


Note: Think C v6. compiler, must set #define USE_MAC_MEMORY 1 in the
	    C compiler header, in order to bypass suspect compiler/lib mem. 
			bug (realloc() fails after a few calls !)
