wxConfigBase class defines the basic interface of all config classes. It can
not be used by itself (it is an abstract base class) and you will always use one
-of its derivations: wxIniConfig, wxFileConfig, wxRegConfig or any other.

+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

which is mapped onto the native wxConfigBase implementation on the given

wxFileConfig otherwise.

\membersection{Static functions}\label{wxconfigstaticfunctions}
These functions deal with the "default" config object. Although its usage is
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.
-Note that wxWindows will delete this config object for you during the program
-shutdown (from \helpref{wxApp::OnExit}{wxapponexit} to be precise) but you can
-also do it yourself earlier if needed.
+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 wxWindows

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 {\tt 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.
