Tk_GetJustify(3) Tk Library Procedures Tk_GetJustify(3)______________________________________________________________________________NAME
Tk_GetJustify, Tk_NameOfJustify - translate between strings and justi‐
fication 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 justifi‐
cation 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 jus‐
tify value it returns a statically-allocated string corresponding to
justify. If justify isn't a legal justify value, then ``unknown justi‐
fication style'' is returned.
