+Not surprisingly, being 'smart' comes at a price of added complexity. This is
reasonable for the situations when you really need to support multiple formats,
but may be annoying if you only want to do something simple like cut and paste
text.
To provide a solution for both cases, wxWindows has two predefined classes

as HTML or text) and \helpref{wxDataObjectComposite}{wxdataobjectcomposite} is
one as soon as you want to transfer data via the clipboard or drag and drop):
