+\func{bool}{HasSubDirs}{\param{const wxString& }{dirspec = wxEmptyString}}

+\func{size\_t}{Traverse}{\param{wxDirTraverser& }{sink}, \param{const wxString& }{filespec = wxEmptyString}, \param{int }{flags = wxDIR\_DEFAULT}}
+
+Enumerate all files and directories under the given directory recursively
+calling the element of the provided \helpref{wxDirTraverser}{wxdirtraverser} 
+object for each of them.
+
+More precisely, the function will really recurse into subdirectories if 
+{\it flags} contains {\tt wxDIR\_DIRS} flag. It will ignore the files (but
+still possibly recurse into subdirectories) if {\tt wxDIR\_FILES} flag is
+given.
+
+For each found directory, \helpref{sink.OnDir()}{wxdirtraverserondir} is called
+and \helpref{sink.OnFile()}{wxdirtraverseronfile} is called for every file.
+Depending on the return value, the enumeration may continue or stop.
+
+The function returns the total number of files found or {\tt (size\_t)-1} on
+error.

+\func{static size\_t}{GetAllFiles}{\param{const wxString& }{dirname}, \param{wxArrayString *}{files}, \param{const wxString& }{filespec = wxEmptyString}, \param{int }{flags = wxDIR\_DEFAULT}}
+
+The function appends the names of all the files under directory {\it dirname} 
+to the array {\it files} (note that its old contents is preserved). Only files
+matching the {\it filespec} are taken, with empty spec matching all the files.
+
+The {\it flags} parameter should always include {\tt wxDIR\_FILES} or the array
+would be unchanged and should include {\tt wxDIR\_DIRS} flag to recurse into
+subdirectories (both flags are included in the value by default).
