</pre><H2>DESCRIPTION</H2>
<P>
The <B>calendar</B> command creates a calendar widget for the selection 
of a date, displaying a single month at a time.  Buttons exist on the 
top to change the month in effect turning the pages of a calendar.  As 
a page is turned, the dates for the month are modified.  Selection of 
a date visually marks that date.  The selected value can be monitored 
via the -command option or just retrieved using the get command.  

</pre><H2>METHODS</H2>
<P>
The <B>calendar</B> command creates a new Tcl command whose
name is <I>pathName</I>.  This
command may be used to invoke various
operations on the widget.  It has the following general form:
<pre>
<I>pathName option </I>?<I>arg arg ...</I>?
</pre>
<I>Option</I> and the <I>arg</I>s
determine the exact behavior of the command.  The following
commands are possible for calendar widgets:

</pre><H2>WIDGET-SPECIFIC METHODS</H2>
<DL>
<DT> <I>pathName <B>cget</B> <I>option</I>
</I></B>
<DD> Returns the current value of the configuration option given
by <I>option</I>.
<I>Option</I> may have any of the values accepted by the <B>calendar</B>
command.
</DL>
<DL>
<DT> <I>pathName</I> <B>configure</B> ?<I>option</I>? ?<I>value option value ...</I>?
</I></B>
<DD> Query or modify the configuration options of the widget.
If no <I>option</I> is specified, returns a list describing all of
the available options for <I>pathName</I> (see <B>Tk_ConfigureInfo</B> for
information on the format of this list).  If <I>option</I> is specified
with no <I>value</I>, 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 <I>option</I> is specified).  If
one or more <I>option-value</I> 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.
<I>Option</I> may have any of the values accepted by the <B>calendar</B>
command.
</DL>
<DL>
<DT> <I>pathName <B>get</B> ?<B>format</B>?
</I></B>
<DD> Returns the currently selected date in a format of 
string or as an integer clock value using the <B>-string</B> and <B>-clicks</B>
format options respectively.  The default is by string.  Reference the 
clock command for more information on obtaining dates and their 
formats.
</DL>
<DL>
<DT> <I>pathName <B>select</B> <I>date</I>
</I></B>
<DD> Changes the currently selected date to the value specified which 
must be in the form of a date string, an integer clock value or as
the keyword "now".  Reference the clock 
command for more information on obtaining dates and their formats.
Note that selecting a date does not change the 
month being shown to that of the date given.  This chore is left
to the <B>show\R command.
</DL>
<DL>
<DT> <I>pathName <B>show</B> <I>date</I>
</I></B>
<DD> Changes the currently displayed date to be that of the date 
argument which must be in the form of a date string, an 
integer clock value or as
the keyword "now".  Reference the clock 
command for more information on obtaining dates and their formats.
