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 ``cen-
ter'').
int *justifyPtr (out) Pointer to location
in which to store
justify value corre-
sponding to string.
Tk_Justify justify (in) Justification style

DESCRIPTION
Tk_GetJustify places in *justifyPtr the justify value cor-
responding 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 cen-
tered; 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 jus-
tification 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.
