wxSimpleHtmlListBox is an implementation of wxHtmlListBox which
shows HTML content in the listbox rows.
- Unlike 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.

The interface exposed by wxSimpleHtmlListBox fully implements the

- wxControlWithItems's documentation for the API reference
- for adding/removing/retrieving items in the listbox.

Thus the only difference between a wxListBox and a wxSimpleHtmlListBox
is that the latter stores strings which can contain HTML fragments (see the
