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 re-
porting.
Tcl_Obj *objPtr (in/out) String value contains name of re-
lief, one of “flat”, “groove”,
“raised”, “ridge”, “solid”, or
“sunken” (or any unique abbrevia-
tion thereof on input); the inter-
nal rep will be modified to cache
corresponding relief value.
char *string (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.
const char *name Name of the relief.
int relief (in) Relief value (one of TK_RE-
LIEF_FLAT, TK_RELIEF_RAISED, TK_RE-
LIEF_SUNKEN, TK_RELIEF_GROOVE,
TK_RELIEF_SOLID, or TK_RE-
LIEF_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 in-
formation 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 de-
scription of the relief is specified with a string instead of an ob-
ject. 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.
