<h2 id="overview">Overview</h2>
<p>The Iwidgets package (also known as [incr Widgets]) is a library extension
for Tcl/Tk versions 8.0 or higher, written in pure Tcl/Tk code. It
requires the compiled packages Itcl and Itk (also known as [incr Tcl] and
[incr Tk], respectively). The download location of these three library
packages is</p>

<p>Tablelist supports interactive cell editing with the aid of the
entryfield, datefield, dateentry, timefield, timeentry, spinner, spinint, and
combobox widgets from the Iwidgets package. 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.</li>
<li class="tm">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>
<p><b>REMARK:</b> The temporary embedded Iwidgets widget used for
interactive cell editing will appear properly scaled, according to the
display's DPI scaling level, given by the variable
<code><b>tablelist::scalingpct</b></code>.</p>

<dt><b>DESCRIPTION</b></dt>
<dd>This command registers the entryfield widget from the Iwidgets package
for interactive cell editing in tablelist widgets. The optional
argument specifies the name to be used for the entryfield 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 the <a href="tablelistTkCore.html">Tk core</a> and <a href=
"tablelistTile.html">tile</a> edit window names. The default is
<code><b>entryfield</b></code>. The command returns its

<b>tablelist::addIncrDateTimeWidget</b> <b>datefield</b>|<b>dateentry</b>|<b>timefield</b>|<b>timeentry</b> ?<b>-seconds</b>? ?<i>name</i>?
</pre>
</dd>
<dt><b>DESCRIPTION</b></dt>
<dd>This command registers the datefield, dateentry, timefield, or
timeentry widget from the Iwidgets package for interactive cell editing in
tablelist widgets. If the <code><b>-seconds</b></code> argument is
present then 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 content of the embedded window used for interactive cell
editing as an integer clock value (in seconds), otherwise as a
string. Use this option for tablelist widgets whose internal list
contains date or time information in seconds (displayed with the aid of
commands given by the <code><b><a href=
"tablelistWidget.html#col_formatcommand">-formatcommand</a></b></code>
column configuration option). The second optional argument specifies
the name to be used for the datefield, dateentry, timefield, or timeentry
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 the <a href="tablelistTkCore.html">Tk core</a> and <a href=
"tablelistTile.html">tile</a> edit window names. The default is
<code><b>datefield</b></code>, <code><b>dateentry</b></code>,
<code><b>timefield</b></code>, or <code><b>timeentry</b></code>, as given
by the first argument. The command returns its
<code><i>name</i></code> argument.</dd>
<dd class="tm">When editing a cell with the aid of the temporary embedded
datefield, dateentry, timefield, or timeentry widget associated with the
above <code><i>name</i></code>, you can use the script corresponding to the
<code><b><a href=
"tablelistWidget.html#editstartcommand">-editstartcommand</a></b></code>
tablelist configuration option to set any of the widget's options, like
<code><b>-gmt</b></code>, <code><b>-iq</b></code>, <code><b>-int</b></code>
("international" date format, supported by datefield and dateentry
widgets), or <code><b>-format</b></code> (for timefield and timeentry
widgets, with the values <code><b>civilian</b></code> and
<code><b>military</b></code>). For the dateentry widget you might
also set the <code><b>-startday</b></code> option to
<code><b>monday</b></code> and the <code><b>-days</b></code> option, e.g.,
to <code>{Mo Tu We Th Fr Sa Su}</code>.</dd>
