-<h2><center>wx.VListBox and wx.HtmlListBox</center></h2>
-<hr>
-
-The "V" in wxVListBox stands for both "virtual" because it can have an
-unlimited number of items since it doesn't store them itself, and
-"variable" since items can vary in height. It has much the same
-interface as wxListBox and also emits the same events so you can use
-the same EVT_LISTBOX function to connect a handler.
-<p>
-
-The wx.HtmlListBox derives from wx.VListBox, but draws each item itself
-as a wx.HtmlCell. This means that you just need to provide a snippet
-of HTML for each item when requested.
