- .SH SYNOPSIS
- .nf

- Tk_Justify
- \fBTk_GetJustify(\fIinterp, string, justifyPtr\fB)\fR
- .sp
- char *

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

- .SH DESCRIPTION
- .PP
- \fBTk_GetJustify\fR places in \fI*justifyPtr\fR the justify value
- corresponding to \fIstring\fR. This value will be one of the following:
- .TP
- \fBTK_JUSTIFY_LEFT\fR
- 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.
- .TP
- \fBTK_JUSTIFY_RIGHT\fR
- 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.
- .TP
- \fBTK_JUSTIFY_CENTER\fR
- Means that the text on each line should be centered; as a result,
- both the left and right edges of lines may be ragged.
- .TP
- \fBTK_JUSTIFY_FILL\fR
- Means that the text on each line should start at the left edge of
- the line and end at the right edge, with the sizes of the spaces
- in the line adjusted to make this work.
- .PP
- Under normal circumstances the return value is \fBTCL_OK\fR and
- \fIinterp\fR is unused.
- If \fIstring\fR doesn't contain a valid justification style
- or an abbreviation of one of these names, then an error message is
- stored in \fIinterp->result\fR, \fBTCL_ERROR\fR is returned, and
- \fI*justifyPtr\fR is unmodified.
- .PP
- \fBTk_NameOfJustify\fR is the logical inverse of \fBTk_GetJustify\fR.
- Given a justify value it returns a statically-allocated string
- corresponding to \fIjustify\fR.
- If \fIjustify\fR isn't a legal justify value, then
- ``unknown justification style'' is returned.

- .SH KEYWORDS
