+<h2><center>wxVListBox and wxHtmlListBox</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 wxHtmlListBox derives from wxVListBox, but draws each item itself
+as a wxHtmlCell.  This means that you just need to provide a snippet
+of HTML for each item when requested.
