<h2 id="overview">Overview</h2>
<p>The BWidget package is a library extension for Tcl/Tk versions 8.1.1 or
higher, written in pure Tcl/Tk code. Its download location is</p>
<blockquote>
<address>
<a href=
"https://sourceforge.net/projects/tcllib/files">https://sourceforge.net/projects/tcllib/files</a>
</address>
</blockquote>
<p>Tablelist supports interactive cell editing with the aid of the Entry,
SpinBox, and ComboBox widgets from the BWidget 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 BWidget 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>
