 119 This demo demonstrates direct editing of all cells of a ListCtrl. To
 120 enable it just include the <b>TextEditMixin</b>. The ListCtrl can be
 121 navigated with the TAB and up/down cursor keys.
 122
 123 <p>Another facet of this demo is that the remaining space of the
 124 ListCtrls is divided over the first three columns. This is achieved
 125 with the extended syntax of <b>ListCtrlAutoWidthMixin</b>:
 126 <code>listmix.ListCtrlAutoWidthMixin.__init__(self, startcol, endcol)</code>
 127 (Look at the general ListCtrl demo for more information about the
 128 ListCtrlAutoWidthMixin)
 129
 130 <p>Finally, the ListCtrl is automatically scrolled, if needed, when
 131 TAB is pressed consecutively (Windows only).
