<h2><a name="overview"></a>Overview</h2>
<p>The tile theme engine is a compiled library extension for Tcl/Tk version
8.4 or higher.&nbsp; Its download location is</p>

</blockquote>
<p>Tablelist supports interactive cell editing with the aid of the tile
entry, combobox, and checkbutton widgets, accessed as
<code><b>ttk::entry</b></code>, <code><b>ttk::combobox</b></code>, and
<code><b>ttk::checkbutton</b></code>, respectively.&nbsp; The version of the
tile package must be 0.5 or higher.&nbsp; Due to the rapidly growing
strategic importance of the tile library, these widgets are automatically
registered for cell editing, hence the only action needed for using one of
them for editing the cells of a given column is as follows:</p>
<p>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
<code><b>ttk::entry</b></code>, <code><b>ttk::combobox</b></code>, or
<code><b>ttk::checkbutton</b></code>, respectively.&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.)</p>
<p>One known limitation of the currently available tile versions is that
the&nbsp; <code><b>style theme use</b></code>&nbsp; command can only be used
to set the current theme, but not to retrieve it.&nbsp; For this reason,
Tablelist makes use of the variable <code><b>tile::currentTheme</b></code>,
which is set by the <code><b>tile::setTheme</b></code> procedure.&nbsp; From
this it follows that the tile widgets used for interactive cell editing will
only be managed as expected if the platform-specific default theme is either
left unchanged or replaced with another theme by invoking the procedure
<code><b>tile::setTheme</b></code>.</p>

The temporary embedded tile entry widget used for interactive cell
editing will be created with an explicitly set value for its
<code><b>-style</b></code> option.&nbsp; Apart from its theme-specific
appearance, it behaves just like its Tk core counterpart.
<p>If an application uses the tile entry widget for interactive cell
editing and also the Wcb package (even if not for that widget), then the
version of Wcb must be 3.1 or higher (because earlier Wcb releases didn't
support any tile widgets).</p>

<h2><a name="combobox"></a>Interactive Cell Editing Using the tile combobox
Widget</h2>
<dl>
<dt><b>DESCRIPTION</b></dt>
<dd>
The temporary embedded tile combobox widget used for interactive cell
editing will be created with an explicitly set value for its
<code><b>-style</b></code> option and with its <code><b>-state</b></code>
option set to <code><b>normal</b></code>, which makes the widget
editable.&nbsp; You can use the script corresponding to the
<code><b><a href=
"tablelistWidget.html#editstartcommand">-editstartcommand</a></b></code>
tablelist configuration option to set the state of the combobox to
<code><b>readonly</b></code> or define validations for it, as well as for
populating its listbox component (with the aid of the combobox widget's
<code><b>-values</b></code> option).
<p>If an application uses the tile combobox widget for interactive cell
editing and also the Wcb package (even if not for that widget), then the
version of Wcb must be 3.1 or higher (because earlier Wcb releases didn't
support any tile widgets).</p>

<dt><b>DESCRIPTION</b></dt>
<dd>The temporary embedded tile checkbutton widget used for interactive
cell editing will be created with explicitly set values for its
<code><b>-style</b></code> and <code><b>-variable</b></code> options.&nbsp;
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 other configuration options, like
<code><b>-offvalue</b></code> and <code><b>-onvalue</b></code>, according
to the <i>internal</i> values of the cells.&nbsp; Since the default values
of the <code><b>-offvalue</b></code> and <code><b>-onvalue</b></code> tile
checkbutton options are <code>0</code> and <code>1</code>, you don't need
to change these options if the cells have the same internal values
<code>0</code> and <code>1</code>.</dd>
