\section{\class{wxDir}}\label{wxdir}
allow enumerating of the files in a directory. wxDir allows enumerate files as
well as directories.
+wxDir also provides a flexible way to enumerate files recursively using
+\helpref{Traverse}{wxdirtraverse} or a simpler
+\helpref{GetAllFiles}{wxdirgetallfiles} function.
+
Example of use:
\begin{verbatim}
wxDIR_DOTDOT = 0x0008, // include '.' and '..'
// by default, enumerate everything except '.' and '..'
- wxDIR_DEFAULT = wxDIR\_FILES | wxDIR\_DIRS | wxDIR\_HIDDEN
+ wxDIR_DEFAULT = wxDIR_FILES | wxDIR_DIRS | wxDIR_HIDDEN
}
\end{verbatim}

-\membersection{wxDir::Exists}\label{wxdirexists}

-\func{static bool}{Exists}{\param{const wxString\& }{dir}}
-
-Test for existence of a directory with the given name
-
\membersection{wxDir::wxDir}\label{wxdirwxdir}
\func{}{wxDir}{\void}
Opens the directory for enumeration, use \helpref{IsOpened()}{wxdirisopened}
to test for errors.
+

\func{}{\destruct{wxDir}}{\void}
-Destructor cleans up the associated ressources. It is not virtual and so this
+Destructor cleans up the associated resources. It is not virtual and so this
class is not meant to be used polymorphically.
-\membersection{wxDir::Open}\label{wxdiropen}
-\func{bool}{Open}{\param{const wxString\& }{dir}}
+\membersection{wxDir::Exists}\label{wxdirexists}
-Open the directory for enumerating, returns TRUE on success or FALSE if an
-error occured.
+\func{static bool}{Exists}{\param{const wxString\& }{dir}}
-\membersection{wxDir::IsOpened}\label{wxdirisopened}
+Test for existence of a directory with the given name
-\constfunc{bool}{IsOpened}{\void}
-Returns TRUE if the directory was successfully opened by a previous call to
-\helpref{Open}{wxdiropen}.
+\membersection{wxDir::GetAllFiles}\label{wxdirgetallfiles}
+
+\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).
+
+See also: \helpref{Traverse}{wxdirtraverse}

\membersection{wxDir::GetFirst}\label{wxdirgetfirst}
\constfunc{bool}{GetFirst}{\param{wxString* }{filename}, \param{const wxString\& }{filespec = wxEmptyString}, \param{int }{flags = wxDIR\_DEFAULT}}
Start enumerating all files matching {\it filespec} (or all files if it is
-empty) and flags, return TRUE on success.
+empty) and flags, return true on success.
+
+
+\membersection{wxDir::GetName}\label{wxdirgetname}
+
+\constfunc{wxString}{GetName}{\void}
+
+Returns the name of the directory itself. The returned string does not have the
+trailing path separator (slash or backslash).
+
\membersection{wxDir::GetNext}\label{wxdirgetnext}
Continue enumerating files satisfying the criteria specified by the last call
to \helpref{GetFirst}{wxdirgetfirst}.
+
+\membersection{wxDir::HasFiles}\label{wxdirhasfiles}
+
+\func{bool}{HasFiles}{\param{const wxString\& }{filespec = wxEmptyString}}
+
+Returns {\tt true} if the directory contains any files matching the given
+{\it filespec}. If {\it filespec} is empty, look for any files at all. In any
+case, even hidden files are taken into account.
+
+
+\membersection{wxDir::HasSubDirs}\label{wxdirhassubdirs}
+
+\func{bool}{HasSubDirs}{\param{const wxString\& }{dirspec = wxEmptyString}}
+
+Returns {\tt true} if the directory contains any subdirectories (if a non
+empty {\it filespec} is given, only check for directories matching it).
+The hidden subdirectories are taken into account as well.
+
+
+\membersection{wxDir::IsOpened}\label{wxdirisopened}
+
+\constfunc{bool}{IsOpened}{\void}
+
+Returns true if the directory was successfully opened by a previous call to
+\helpref{Open}{wxdiropen}.
+
+
+\membersection{wxDir::Open}\label{wxdiropen}
+
+\func{bool}{Open}{\param{const wxString\& }{dir}}
+
+Open the directory for enumerating, returns true on success or false if an
+error occurred.
+
+
+\membersection{wxDir::Traverse}\label{wxdirtraverse}
+
+\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.
