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)

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.

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.
