	101	<h2><center>wxVListBox and wxHtmlListBox</center></h2>
	102	<hr>
	103
	104	The "V" in wxVListBox stands for both "virtual" because it can have an
	105	unlimited number of items since it doesn't store them itself, and
	106	"variable" since items can vary in height. It has much the same
	107	interface as wxListBox and also emits the same events so you can use
	108	the same EVT_LISTBOX function to connect a handler.
	109	<p>
	110
	111	The wxHtmlListBox derives from wxVListBox, but draws each item itself
	112	as a wxHtmlCell. This means that you just need to provide a snippet
	113	of HTML for each item when requested.
