NAME
Tk_GetJustifyFromObj, Tk_GetJustify, Tk_NameOfJustify - translate between strings and justification styles
SYNOPSIS
#include <tk.h> int Tk_GetJustifyFromObj(interp, objPtr, justifyPtr) int Tk_GetJustify(interp, string, justifyPtr) const char * Tk_NameOfJustify(justify)
ARGUMENTS
Tcl_Interp *interp (in) Interpreter to use for error reporting, or NULL. Tcl_Obj *objPtr (in/out) String value contains name of justification style, one of "left", "right", or "center". The internal rep will be modified to cache corresponding justify value. const char *string (in) Same as objPtr except description of justification style is passed as a string. int *justifyPtr (out) Pointer to location in which to store justify value corresponding to objPtr or string. Tk_Justify justify (in) Justification style (one of the values listed below). _________________________________________________________________
DESCRIPTION
Tk_GetJustifyFromObj places in *justifyPtr the justify value corresponding to objPtr's value. This value will be one of the following: TK_JUSTIFY_LEFT Means that the text on each line should start at the left edge of the line; as a result, the right edges of lines may be ragged. TK_JUSTIFY_RIGHT Means that the text on each line should end at the right edge of the line; as a result, the left edges of lines may be ragged. TK_JUSTIFY_CENTER Means that the text on each line should be centered; as a result, both the left and right edges of lines may be ragged. Under normal circumstances the return value is TCL_OK and interp is unused. If objPtr does not contain a valid justification style or an abbreviation of one of these names, TCL_ERROR is returned, *justifyPtr is unmodified, and an error message is stored in interp's result if interp is not NULL. Tk_GetJustifyFromObj caches information about the return value in objPtr, which speeds up future calls to Tk_GetJusti- fyFromObj with the same objPtr. Tk_GetJustify is identical to Tk_GetJustifyFromObj except that the description of the justification is specified with a string instead of an object. This prevents Tk_GetJustify from caching the return value, so Tk_GetJustify is less efficient than Tk_GetJustifyFromObj. Tk_NameOfJustify is the logical inverse of Tk_GetJustify. Given a justify value it returns a statically-allocated string corresponding to justify. If justify is not a legal justify value, then "unknown justification style" is returned.
