______________________________________________________________________________


NAME

       Tk_GetReliefFromObj, Tk_GetRelief, Tk_NameOfRelief - translate between
       strings and relief values


SYNOPSIS

       #include <tk.h>

       int
       Tk_GetReliefFromObj(interp, objPtr, reliefPtr)

       int
       Tk_GetRelief(interp, name, reliefPtr)

       const char *
       Tk_NameOfRelief(relief)


ARGUMENTS

       Tcl_Interp *interp (in)             Interpreter to use for error
                                           reporting.

       Tcl_Obj *objPtr (in/out)            String value contains name of
                                           relief, one of "flat", "groove",
                                           "raised", "ridge", "solid", or
                                           "sunken" (or any unique
                                           abbreviation thereof on input); the
                                           internal rep will be modified to
                                           cache corresponding relief value.

       const char *name (in)               Same as objPtr except description
                                           of relief is passed as a string.

       int *reliefPtr (out)                Pointer to location in which to
                                           store relief value corresponding to
                                           objPtr or name.

       int relief (in)                     Relief value (one of
                                           TK_RELIEF_FLAT, TK_RELIEF_RAISED,
                                           TK_RELIEF_SUNKEN, TK_RELIEF_GROOVE,
                                           TK_RELIEF_SOLID, or
                                           TK_RELIEF_RIDGE).
______________________________________________________________________________


DESCRIPTION

       Tk_GetReliefFromObj places in *reliefPtr the relief value corresponding
       to the value of objPtr.  This value will be one of TK_RELIEF_FLAT,
       TK_RELIEF_RAISED, TK_RELIEF_SUNKEN, TK_RELIEF_GROOVE, TK_RELIEF_SOLID,
       or TK_RELIEF_RIDGE.  Under normal circumstances the return value is
       TCL_OK and interp is unused.  If objPtr does not contain one of the
       valid relief names or an abbreviation of one of them, then TCL_ERROR is
       returned, *reliefPtr is unmodified, and an error message is stored in
       interp's result if interp is not NULL.  Tk_GetReliefFromObj caches
       information about the return value in objPtr, which speeds up future
       calls to Tk_GetReliefFromObj with the same objPtr.

       Tk_GetRelief is identical to Tk_GetReliefFromObj except that the
       description of the relief is specified with a string instead of an
       object.  This prevents Tk_GetRelief from caching the return value, so
       Tk_GetRelief is less efficient than Tk_GetReliefFromObj.

       Tk_NameOfRelief is the logical inverse of Tk_GetRelief.  Given a relief
       value it returns the corresponding string (flat, raised, sunken,
       groove, solid, or ridge).  If relief is not a legal relief value, then
       "unknown relief" is returned.
