NAME
Tk_GetAnchorFromObj, Tk_GetAnchor, Tk_NameOfAnchor - translate between strings and anchor positions SYNOPSIS
#include <tk.h> int | Tk_GetAnchorFromObj(interp, objPtr, anchorPtr) | int Tk_GetAnchor(interp, string, anchorPtr) CONST char * Tk_NameOfAnchor(anchor) ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for error reporting, or NULL. Tcl_Obj *objPtr (in/out) | String value contains name of anchor point: n, ne, e, se, s, sw, w, nw, or center; internal rep will be | modified to cache corresponding Tk_Anchor. | CONST char *string (in) | Same as objPtr except description of anchor point is passed as a string. int *anchorPtr (out) Pointer to location in which to store anchor position corresponding to objPtr or string. Tk_Anchor anchor (in) Anchor position, e.g. TCL_ANCHOR_CENTER. _________________________________________________________________ DESCRIPTION
Tk_GetAnchorFromObj places in *anchorPtr an anchor position (enumerated type Tk_Anchor) corresponding to objPtr's value. The result will | be one of TK_ANCHOR_N, TK_ANCHOR_NE, TK_ANCHOR_E, TK_ANCHOR_SE, TK_ANCHOR_S, TK_ANCHOR_SW, TK_ANCHOR_W, TK_ANCHOR_NW, or TK_ANCHOR_CENTER. | Anchor positions are typically used for indicating a point on an object that will be used to position the object, e.g. TK_ANCHOR_N means | position the top center point of the object at a particular place. | Under normal circumstances the return value is TCL_OK and interp is unused. If string doesn't contain a valid anchor position or an abbre- | viation of one of these names, TCL_ERROR is returned, *anchorPtr is unmodified, and an error message is stored in interp's result if interp | isn't NULL. Tk_GetAnchorFromObj caches information about the return value in objPtr, which speeds up future calls to Tk_GetAnchorFromObj | with the same objPtr. | Tk_GetAnchor is identical to Tk_GetAnchorFromObj except that the description of the anchor is specified with a string instead of an object. | This prevents Tk_GetAnchor from caching the return value, so Tk_GetAnchor is less efficient than Tk_GetAnchorFromObj. Tk_NameOfAnchor is the logical inverse of Tk_GetAnchor. Given an anchor position such as TK_ANCHOR_N it returns a statically-allocated string corresponding to anchor. If anchor isn't a legal anchor value, then ``unknown anchor position'' is returned. KEYWORDS

NAME
Tk_GetAnchorFromObj, Tk_GetAnchor, Tk_NameOfAnchor - translate between strings and anchor positions SYNOPSIS
#include <tk.h> int Tk_GetAnchorFromObj(interp, objPtr, anchorPtr) int Tk_GetAnchor(interp, string, anchorPtr) const char * Tk_NameOfAnchor(anchor) ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for error reporting, or NULL. Tcl_Obj *objPtr (in/out) String value contains name of anchor point: "n", "ne", "e", "se", "s", "sw", "w", "nw", or "center"; internal rep will be modified to cache corresponding Tk_Anchor. const char *string (in) Same as objPtr except description of anchor point is passed as a string. int *anchorPtr (out) Pointer to location in which to store anchor position corresponding to objPtr or string. Tk_Anchor anchor (in) Anchor position, e.g. TCL_ANCHOR_CENTER. _________________________________________________________________ DESCRIPTION
Tk_GetAnchorFromObj places in *anchorPtr an anchor position (enumerated type Tk_Anchor) corresponding to objPtr's value. The result will be one of TK_ANCHOR_N, TK_ANCHOR_NE, TK_ANCHOR_E, TK_ANCHOR_SE, TK_ANCHOR_S, TK_ANCHOR_SW, TK_ANCHOR_W, TK_ANCHOR_NW, or TK_ANCHOR_CENTER. Anchor positions are typically used for indicating a point on an object that will be used to position the object, e.g. TK_ANCHOR_N means position the top center point of the object at a particular place. Under normal circumstances the return value is TCL_OK and interp is unused. If string does not contain a valid anchor position or an abbreviation of one of these names, TCL_ERROR is returned, *anchorPtr is unmodified, and an error message is stored in interp's result if interp is not NULL. Tk_GetAnchorFromObj caches information about the return value in objPtr, which speeds up future calls to Tk_GetAnchor- FromObj with the same objPtr. Tk_GetAnchor is identical to Tk_GetAnchorFromObj except that the description of the anchor is specified with a string instead of an object. This prevents Tk_GetAnchor from caching the return value, so Tk_GetAnchor is less efficient than Tk_GetAnchorFromObj. Tk_NameOfAnchor is the logical inverse of Tk_GetAnchor. Given an anchor position such as TK_ANCHOR_N it returns a statically-allocated string corresponding to anchor. If anchor is not a legal anchor value, then "unknown anchor position" is returned.
