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” - or a unique
                                            abbreviation  of  one.   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_GetJustifyFromObj 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.
