+not be used by itself (it is an abstract base class) and you will always use one
+of its derivations: \helpref{wxFileConfig}{wxfileconfig},
+wxRegConfig or any other.
However, usually you don't even need to know the precise nature of the class
you're working with but you would just use the wxConfigBase methods. This
allows you to write the same code regardless of whether you're working with
the registry under Win32 or text-based config files under Unix (or even
Windows 3.1 .INI files if you're really unlucky). To make writing the portable
-code even easier, wxWindows provides a typedef wxConfig
+code even easier, wxWidgets provides a typedef wxConfig
which is mapped onto the native wxConfigBase implementation on the given
-platform: i.e. wxRegConfig under Win32, wxIniConfig under Win16 and

wxFileConfig otherwise.

-\membersection{Static functions}

+\membersection{Static functions}\label{wxconfigstaticfunctions}
These functions deal with the "default" config object. Although its usage is
not at all mandatory it may be convenient to use a global config object
one (especially because creating a wxFileConfig object might be a time
consuming operation). In this case, you may create this global config object
in the very start of the program and {\it Set()} it as the default. Then, from
-anywhere in your program, you may access it using the {\it Get()} function. Of
-course, you should delete it on the program termination (otherwise, not only a
-memory leak will result, but even more importantly the changes won't be
-written back!).
+anywhere in your program, you may access it using the {\it Get()} function.
+This global wxConfig object will be deleted by wxWidgets automatically if it
+exists. Note that this implies that if you do delete this object yourself
+(usually in \helpref{wxApp::OnExit}{wxapponexit}) you must use {\it Set(NULL)}
+to prevent wxWidgets from deleting it the second time.
As it happens, you may even further simplify the procedure described above:
you may forget about calling {\it Set()}. When {\it Get()} is called and there
is no current object, it will create one using {\it Create()} function. To
disable this behaviour {\it DontCreateOnDemand()} is provided.
+{\bf Note:} You should use either {\it Set()} or {\it Get()} because wxWidgets
+library itself would take advantage of it and could save various information
+in it. For example \helpref{wxFontMapper}{wxfontmapper} or Unix version
+of \helpref{wxFileDialog}{wxfiledialog} have the ability to use wxConfig class.

+\membersection{Path management}\label{configpathmanagement}
+
+As explained in \helpref{config overview}{wxconfigoverview}, the config classes
support a file system-like hierarchy of keys (files) and groups (directories).
As in the file system case, to specify a key in the config class you must use
a path to it. Config classes also support the notion of the current group,
which makes it possible to use the relative paths. To clarify all this, here
-is an example (it's only for the sake of demonstration, it doesn't do anything

from running several enumerations simultaneously, that's why you must pass it
explicitly.
Having said all this, enumerating the config entries/groups is very simple:

+\membersection{Key access}\label{configkeyaccess}
These function are the core of wxConfigBase class: they allow you to read and
write config file data. All {\it Read} function take a default value which
will be returned if the specified key is not found in the config file.
-Currently, only two types of data are supported: string and long (but it might
-change in the near future). To work with other types: for {\it int} or {\it
-bool} you can work with function taking/returning {\it long} and just use the
-casts. Better yet, just use {\it long} for all variables which you're going to
-save in the config file: chances are that \verb$sizeof(bool) == sizeof(int) == sizeof(long)$ anyhow on your system. For {\it float}, {\it double} and, in
-general, any other type you'd have to translate them to/from string
-representation and use string functions.
+Currently, supported types of data are:
+\helpref{wxString}{wxstring}, {\it long}, {\it double}, {\it bool},
+\helpref{wxColour}{wxcolour} and any other types,
+for which functions \helpref{wxToString}{wxtostring}
+and \helpref{wxFromString}{wxfromstring} are defined.
Try not to read long values into string variables and vice versa: although it
just might work with wxFileConfig, you will get a system error with

+The functions in this section allow to rename entries or subgroups of the
+current group. They will return \false on error. typically because either the
+entry/group with the original name doesn't exist, because the entry/group with
+the new name already exists or because the function is not supported in this

+
+\membersection{Options}\label{configoptions}
Some aspects of wxConfigBase behaviour can be changed during run-time. The
first of them is the expansion of environment variables in the string values
# the following syntax is valud only under Windows
UserData = %windir%\\data.dat
\end{verbatim}
-
-the call to \verb$config->Read("UserData")$ will return something like
-\verb$"/home/zeitlin/data"$ if you're lucky enough to run a Linux system ;-)
+% $ % help EMACS syntax highlighting...
+the call to {\tt config->Read("UserData")} will return something like
+{\tt "/home/zeitlin/data"} if you're lucky enough to run a Linux system ;-)
Although this feature is very useful, it may be annoying if you read a value
which containts '\$' or '\%' symbols (\% is used for environment variables
expansion under Windows) which are not used for environment variable
-expansion. In this situation you may call SetExpandEnvVars(FALSE) just before
-reading this value and SetExpandEnvVars(TRUE) just after. Another solution

+
+\docparam{style}{Can be one of wxCONFIG\_USE\_LOCAL\_FILE and
+wxCONFIG\_USE\_GLOBAL\_FILE. The style interpretation depends on the config
+class and is ignored by some implementations. For wxFileConfig, these styles
+determine whether a local or global config file is created or used: if
+wxCONFIG\_USE\_GLOBAL\_FILE is used, then settings are read from the global
+config file and if wxCONFIG\_USE\_LOCAL\_FILE is used, settings are read from
+and written to local config file (if they are both set, global file is read
+first, then local file, overwriting global settings). If the
+flag is present but the parameter is empty, the parameter will be set to a
+default. If the parameter is present but the style flag not, the relevant flag
+will be added to the style. For wxRegConfig, thie GLOBAL flag refers to HKLM
+key while LOCAL one is for the usual HKCU one.
+
+For wxFileConfig you can also add wxCONFIG\_USE\_RELATIVE\_PATH by logically
+or'ing it to either of the \_FILE options to tell wxFileConfig to use relative
+instead of absolute paths.
+
+On non-VMS Unix systems, the default local configuration file is \tt{~/.appname}.
+However, this path may be also used as user data directory
+(see \helpref{wxStandardPaths::GetUserDataDir}{wxstandardpathsgetuserdatadir}) if
+the application has several data files. In this case wxCONFIG\_USE\_SUBDIR

+For wxFileConfig, you can also add wxCONFIG\_USE\_NO\_ESCAPE\_CHARACTERS which
+will turn off character escaping for the values of entries stored in the config
+file: for example a {\it foo} key with some backslash characters will be stored
+as {\tt foo=C:$\backslash$mydir} instead of the usual storage of {\tt
+foo=C:$\backslash\backslash$mydir}.
+
+The wxCONFIG\_USE\_NO\_ESCAPE\_CHARACTERS style can be helpful if your config
+file must be read or written to by a non-wxWidgets program (which might not
+understand the escape characters). Note, however, that if
