overview = """\
<html>
<body>

This demo demonstrates direct editing of all cells of a ListCtrl. To
enable it just include the <b>TextEditMixin</b>. The ListCtrl can be
navigated with the TAB and up/down cursor keys.

<p>Another facet of this demo is that the remaining space of the
ListCtrls is divided over the first three columns. This is achieved
with the extended syntax of <b>ListCtrlAutoWidthMixin</b>:
<code>listmix.ListCtrlAutoWidthMixin.__init__(self, startcol, endcol)</code>
(Look at the general ListCtrl demo for more information about the
ListCtrlAutoWidthMixin)

<p>Finally, the ListCtrl is automatically scrolled, if needed, when
TAB is pressed consecutively (Windows only).
