tk4.2 C API - GetJustify
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;
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.
