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). |
_________________________________________________________________
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.
