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 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 string doesn't contain a valid justification 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.
