+\subsection{Native font information}\label{nativefontinformation}
+
+An alternative way of choosing fonts is to use the native font description.
+This is the only acceptable solution if the user is allowed to choose the font
+using the \helpref{wxFontDialog}{wxfontdialog} because the selected font cannot
+be described using only the family name and so, if only family name is stored
