not be used by itself (it is an abstract base class) and you will always use one

However, usually you don't even need to know the precise nature of the class
Windows 3.1 .INI files if you're really unlucky). To make writing the portable
code even easier, wxWidgets provides a typedef wxConfig
which is mapped onto the native wxConfigBase implementation on the given

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}.
+For wxRegConfig, this flag refers to HKLM, and provides read-only access.
