<p>Tablelist supports interactive cell editing with the aid of the combobox
widget implemented in the package mentioned above.&nbsp; The steps needed for
using this widget for editing the cells of a given column are as follows:</p>
<ol>
<li>Register the combobox widget for interactive cell editing by invoking
the <code><b><a href=
"#combobox">tablelist::addOakleyCombobox</a></b></code> command described
below.<br>
&nbsp;</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.&nbsp; (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>

</dd>
<dt><b>DESCRIPTION</b></dt>
<dd>This command registers Bryan Oakley's combobox widget for interactive
cell editing in tablelist widgets.&nbsp; The optional argument specifies
the name to be used for the combobox widget as the value of the
<code><b><a href=
"tablelistWidget.html#col_editwindow">-editwindow</a></b></code> column or
cell configuration option.&nbsp; 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>.&nbsp; The default is
<code><b>combobox</b></code>.&nbsp; The command returns its
<code><i>name</i></code> argument.</dd>
<dd><br>
The temporary embedded combobox widget associated with the above
<code><i>name</i></code> will be created with its
<code><b>-editable</b></code> option set to <code>1</code>.&nbsp; You can
use the script corresponding to the <code><b><a href=
"tablelistWidget.html#editstartcommand">-editstartcommand</a></b></code>
tablelist configuration option to make the combobox non-editable or define
validations for its entry child (whose path name can be obtained by
invoking the tablelist widget's <code><b><a href=
"tablelistWidget.html#entrypath">entrypath</a></b></code> subcommand, or by
appending <code><b>.entry</b></code> to the path name of the combobox
widget, or, if using combobox version 2.3 or later, with the aid of the
combobox widget's&nbsp; <code><b>subwidget entry</b></code>&nbsp;
subcommand), as well as for populating its listbox component (by using the
combobox widget's&nbsp; <code><b>list insert</b></code>&nbsp;
subcommand).</dd>
