Tk_NameOfJustify





Tk_GetJustify(3)      Tk Library Procedures                   4.0



_________________________________________________________________

NAME

Tk_GetJustify, Tk_NameOfJustify - translate between strings and justification styles

SYNOPSIS

#include <tk.h> Tk_Justify Tk_GetJustify(interp, string, justifyPtr) char * Tk_NameOfJustify(justify)

ARGUMENTS

Tcl_Interp *interp (in) Interpreter to use for error reporting. char *string (in) String containing name of justification style (``left'', ``right'', or ``center''). int *justifyPtr (out) Pointer to location in which to store justify value corresponding to string. Tk_Justify justify (in) Justification style (one of the values listed below). _________________________________________________________________

DESCRIPTION

Tk_GetJustify places in *justifyPtr the justify value corresponding to string. This value will be one of the fol- lowing: 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; Tk 1 Tk_GetJustify(3) Tk Library Procedures 4.0 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 string doesn't contain a valid justif- ication style or an abbreviation of one of these names, then an error message is stored in interp->result, TCL_ERROR is returned, and *justifyPtr is unmodified. Tk_NameOfJustify is the logical inverse of Tk_GetJustify. Given a justify value it returns a statically-allocated string corresponding to justify. If justify isn't a legal justify value, then ``unknown justification style'' is returned.
