.SH DESCRIPTION
.PP
The \fBtimefield\fR command creates an enhanced text entry widget for
the purpose of time entry with various degrees of built-in intelligence.
.DE

.SH "METHODS"
.PP
The \fBtimefield\fR command creates a new Tcl command whose
name is \fIpathName\fR.  This
command may be used to invoke various
operations on the widget.  It has the following general form:
.DS C
\fIpathName option \fR?\fIarg arg ...\fR?
.DE
\fIOption\fR and the \fIarg\fRs
determine the exact behavior of the command.  The following
commands are possible for timefield widgets:
.SH "WIDGET-SPECIFIC METHODS"
.TP
\fIpathName \fBcget\fR \fIoption\fR
Returns the current value of the configuration option given
by \fIoption\fR.
\fIOption\fR may have any of the values accepted by the \fBtimefield\fR
command.
.TP
\fIpathName\fR \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR?
Query or modify the configuration options of the widget.
If no \fIoption\fR is specified, returns a list describing all of
the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for
information on the format of this list).  If \fIoption\fR is specified
with no \fIvalue\fR, then the command returns a list describing the
one named option (this list will be identical to the corresponding
sublist of the value returned if no \fIoption\fR is specified).  If
one or more \fIoption\-value\fR pairs are specified, then the command
modifies the given widget option(s) to have the given value(s);  in
this case the command returns an empty string.
\fIOption\fR may have any of the values accepted by the \fBtimefield\fR
command.
.TP
\fIpathName \fBget\fR ?\fBformat\fR?
Returns the current contents of the timefield in a format of 
string or as an integer clock value using the \fB-string\fR and \fB-clicks\fR
format options respectively.  The default is by string.  Reference the 
clock command for more information on obtaining times and their 
formats.
.TP
\fIpathName \fBisvalid\fR
Returns a boolean indication of the validity of the currently
displayed time value.  For example, 12:59:59 is valid whereas
25:59:59 is invalid.
.TP
\fIpathName \fBshow\fR \fItime\fR
Changes the currently displayed time to be that of the time 
argument.  The time may be specified either as a string, an
integer clock value or the keyword "now" (the default). 
Reference the clock command for more information on obtaining
times and their formats.
