tk_getrelieffromobj(3)

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); internal 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_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 doesn't 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 isn't 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 isn't a legal relief value, then ``unknown relief'' is returned.
