Tk_GetReliefFromObj(3)       Tk Library Procedures      Tk_GetReliefFromObj(3)



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


#include <tk.h> int Tk_GetReliefFromObj(interp, objPtr, reliefPtr) int Tk_GetRelief(interp, name, reliefPtr) const char * Tk_NameOfRelief(relief)


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. 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). ______________________________________________________________________________


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.
