<h2><a name="overview"></a>Overview</h2>
<p>The multi-entry package Mentry is a library extension for Tcl/Tk version
8.0 or higher, written in pure Tcl/Tk code. Its download location
is</p>
<blockquote>
<address>
<a href="http://www.nemethi.de">http://www.nemethi.de</a>
</address>
</blockquote>
<p>Starting with version 3.0, the Mentry distribution provides not only the
package Mentry, but also its tile-based equivalent Mentry_tile, which enables
the theme-specific appearance of mentry widgets; this package requires Tcl/Tk
8.4 or higher and tile 0.6 or higher.</p>
<p>Tablelist supports interactive cell editing with the aid of the mentry
widgets of type <code>"Date"</code>, <code>"Time"</code>,
<code>"DateTime</code>, <code>"FixedPoint"</code>, and
<code>"IPAddr"</code>. The steps needed for using one of these widgets
for editing the cells of a given column are as follows:</p>
<ol>
<li>Register the desired widget for interactive cell editing by invoking
one of the commands described in this reference page.<br>
</li>
<li>Use the tablelist widget's <code><b><a href=
"tablelistWidget.html#columnconfigure">columnconfigure</a></b></code>
subcommand to set the given column's <code><b><a href=
"tablelistWidget.html#col_editable">-editable</a></b></code> option to true
and its <code><b><a href=
"tablelistWidget.html#col_editwindow">-editwindow</a></b></code> option to
the value returned by the command mentioned above. (These options are
supported at cell level, too, with the aid of the <code><b><a href=
"tablelistWidget.html#cellconfigure">cellconfigure</a></b></code>
subcommand.)</li>
</ol>

<b>SYNOPSIS</b></dt>
<dd>
<pre>
<b>tablelist::addDateMentry</b> <i>format separator</i> ?<b>-gmt</b>? ?<i>name</i>?
</pre>
</dd>
<dt><b>DESCRIPTION</b></dt>
<dd>This command registers the widget created by the
<code><b>mentry::dateMentry</b></code> command from the Mentry (or
Mentry_tile) package for interactive cell editing in tablelist
widgets. The <code><i>format</i></code> and
<code><i>separator</i></code> arguments have the same meanings as in the
<code><b>mentry::dateMentry</b></code> command. If the
<code><b>-gmt</b></code> argument is present then both the internal clock
value and its external date representation in the mentry widget will be
viewed as Greenwich Mean Time, otherwise as local time. The second
optional argument specifies the name to be used for the mentry widget as
the value of the <code><b><a href=
"tablelistWidget.html#col_editwindow">-editwindow</a></b></code> column or
cell configuration option. It may be any string that is different
from <code><b>entry</b></code>, <code><b>text</b></code>,
<code><b>spinbox</b></code>, <code><b>checkbutton</b></code>,
<code><b>ttk::entry</b></code>, <code><b>ttk::checkbutton</b></code>, and
<code><b>ttk::combobox</b></code>. The default is
<code><b>dateMentry</b></code>. The command returns its
<code><i>name</i></code> argument.</dd>
<dd><br>
A tablelist column having the above <code><i>name</i></code> as the value
of its <code><b>-editwindow</b></code> option must contain as internal cell
values date information in seconds (displayed with the aid of a command
given by the <code><b><a href=
"tablelistWidget.html#col_formatcommand">-formatcommand</a></b></code>
column configuration option). The <code><b><a href=
"tablelistWidget.html#finishediting">finishediting</a></b></code>
subcommand of the Tcl command associated with the tablelist widget will
retrieve the contents of the embedded window used for interactive cell
editing by invoking the <code><b>mentry::getClockVal</b></code>
command. The value returned by this command (a clock value in seconds
or one of the error strings <code>"EMPTY"</code>, <code>"BAD"</code>,
<code>"BAD_DATE"</code>, or <code>"BAD_YEAR"</code>) will be passed to the
script corresponding to the <code><b><a href=
"tablelistWidget.html#editendcommand">-editendcommand</a></b></code>
tablelist configuration option (if any), as its last argument. If
this value is one of the above error strings then the script should reject
the mentry's contents by invoking the <code><b><a href=
"tablelistWidget.html#rejectinput">rejectinput</a></b></code>
subcommand.</dd>
