<p>Tablelist supports interactive cell editing with the aid of the combobox
|
|
widget implemented in the package mentioned above. 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>
|
|
</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>

|
|
|
|
<dd>This command registers Bryan Oakley's combobox widget for interactive
|
|
cell editing in tablelist widgets. 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. 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>combobox</b></code>. 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>. 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 <code><b>subwidget entry</b></code>
|
|
subcommand), as well as for populating its listbox component (by using the
|
|
combobox widget's <code><b>list insert</b></code>
|
|
subcommand).</dd>
