\section{\class{wxFileConfig}}\label{wxfileconfig}

wxFileConfig implements \helpref{wxConfigBase}{wxconfigbase} interface for
storing and retrieving configuration information using plain text files. The
files have a simple format reminiscent of Windows INI files with lines of the
form \texttt{key = value} defining the keys and lines of special form
\texttt{$[$group$]$} indicating the start of each group.

This class is used by default for wxConfig on Unix platforms but may also be
used explicitly if you want to use files and not the registry even under
Windows.

\helponly{\insertatlevel{2}{\wxheading{Members}}}

\membersection{wxFileConfig::wxFileConfig}\label{wxfileconfigctor}

\func{}{wxFileConfig}{\param{wxInputStream\& }{is}, \param{const wxMBConv\& }{conv = wxConvAuto()}}

Read the config data from the specified stream instead of the associated file,
as usual.

\helpref{Save}{wxfileconfigsave}


\membersection{wxFileName::GetGlobalFile}\label{wxfilenamegetglobalfile}

\func{static wxFileName}{GetGlobalFile}{\param{const wxString\& }{basename}}

Return the full path to the file which would be used by wxFileConfig as global,
system-wide, file if it were constructed with \arg{basename} as ``global
filename'' parameter in the constructor. Notice that this function cannot be
used if \arg{basename} is already a full path name.


\membersection{wxFileName::GetLocalFile}\label{wxfilenamegetlocalfile}

\func{static wxFileName}{GetLocalFile}{\param{const wxString\& }{basename}, \param{int }{style = $0$}}

Return the full path to the file which would be used by wxFileConfig as local,
user-specific, file if it were constructed with \arg{basename} as ``local
filename'' parameter in the constructor.

\arg{style} has the same meaning as in \helpref{constructor}{wxconfigbasector} 
and can contain any combination of styles but only wxCONFIG\_USE\_SUBDIR bit is
examined by this function.

Notice that this function cannot be used if \arg{basename} is already a full
path name.


\membersection{wxFileConfig::Save}\label{wxfileconfigsave}

\func{bool}{Save}{\param{wxOutputStream\& }{os}, \param{const wxMBConv\& }{conv = wxConvAuto()}}

Saves all config data to the given stream, returns \true if data was saved
successfully or \false on error.

Note the interaction of this function with the internal ``dirty flag'': the
data is saved unconditionally, i.e. even if the object is not dirty. However
after saving it successfully, the dirty flag is reset so no changes will be
written back to the file this object is associated with until you change its
contents again.

\helpref{Flush}{wxconfigbaseflush}


\membersection{wxFileConfig::SetUmask}\label{wxfileconfigsetumask}

\func{void}{SetUmask}{\param{int }{mode}}

Allows to set the mode to be used for the config file creation. For example, to
create a config file which is not readable by other users (useful if it stores
some sensitive information, such as passwords), you could use 
{\tt SetUmask(0077)}.

This function doesn't do anything on non-Unix platforms.
