There's another way of taking advantage of this class: you can use it in your code and use
platform native icons as provided by \helpref{wxArtProvider::GetBitmap}{wxartprovidergetbitmap} or
\helpref{wxArtProvider::GetIcon}{wxartprovidergeticon} (NB: this is not yet really

\helpref{wxArtProvider::GetBitmap}{wxartprovidergetbitmap} or
+\helpref{wxArtProvider::GetIconBundle}{wxartprovidergeticonbundle} or
\helpref{wxArtProvider::GetIcon}{wxartprovidergeticon}
