+\constfunc{bool}{IsDir}{\void}
+
+Returns {\tt true} if this object represents a directory, {\tt false} otherwise
+(i.e. if it is a file). Note that this method doesn't test whether the
+directory or file really exists, you should use
+\helpref{DirExists}{wxfilenamedirexists} or
+\helpref{FileExists}{wxfilenamefileexists} for this.

+\membersection{wxFileName::MakeAbsolute}\label{wxfilenamemakeabsolute}
+
+\func{bool}{MakeAbsolute}{\param{const wxString\& }{cwd = wxEmptyString}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
+
+Make the file name absolute. This is a shortcut for
+{\tt \helpref{Normalize}{wxfilenamenormalize}(wxPATH\_NORM\_DOTS | wxPATH\_NORM\_ABSOLUTE | wxPATH\_NORM\_TILDE, cwd, format)}.

+\membersection{wxFileName::MakeRelativeTo}\label{wxfilenamemakerelativeto}
+
+\func{bool}{MakeRelativeTo}{\param{const wxString\& }{pathBase = ""}, \param{wxPathFormat }{format = wxPATH\_NATIVE}}
+
+This function tries to put this file name in a form relative to {\it pathBase}.
+In other words, it returns the file name which should be used to access this
+file if the current directory were {\it pathBase}.
