wxHtmlListBox is an implementation of \helpref{wxVListBox}{wxvlistbox} which
shows HTML content in the listbox rows. This is still an abstract base class
and you will need to derive your own class from it (see htlbox sample for the
-example) but you will only need to override a single

+\section{\class{wxSimpleHtmlListBox}}\label{wxsimplehtmllistbox}
+
+wxSimpleHtmlListBox is an implementation of \helpref{wxHtmlListBox}{wxhtmllistbox} which
+shows HTML content in the listbox rows.
+
+Unlike \helpref{wxHtmlListBox}{wxhtmllistbox}, this is not an abstract class and thus it
+has the advantage that you can use it without deriving your own class from it.
+However, it also has the disadvantage that this is not a virtual control and thus it's not
+well-suited for those cases where you need to show a huge number of items: every time you
+add/insert a string, it will be stored internally and thus will take memory.
+
+The interface exposed by wxSimpleHtmlListBox fully implements the
+\helpref{wxControlWithItems}{wxcontrolwithitems} interface, thus you should refer to
+\helpref{wxControlWithItems}{wxcontrolwithitems}'s documentation for the API reference
+for adding/removing/retrieving items in the listbox.
+Also note that the \helpref{wxVListBox::SetItemCount}{wxvlistboxsetitemcount} function is
+{\tt protected} in wxSimpleHtmlListBox's context so that you cannot call it directly,
+wxSimpleHtmlListBox will do it for you.
+
+Note: in case you need to append a lot of items to the control at once, make sure to use the
+\helpref{Append(const wxArrayString \&)}{wxcontrolwithitemsappend} function.
+
+Thus the only difference between a \helpref{wxListBox}{wxlistbox} and a wxSimpleHtmlListBox
+is that the latter stores strings which can contain HTML fragments (see the list of
+\helpref{tags supported by wxHTML}{htmltagssupported}).
+
+Note that the HTML strings you fetch to wxSimpleHtmlListBox should not contain the {\tt <html>}
+or {\tt <body>} tags.
