even look at it: it is just a "cookie" which stores the state of the
enumeration. It can't be stored inside the class because it would prevent you
from running several enumerations simultaneously, that's why you must pass it

Although this feature is very useful, it may be annoying if you read a value

\membersection{wxConfigBase::Get}\label{wxconfigbaseget}
-\func{wxConfigBase *}{Get}{\param{bool }{CreateOnDemand = TRUE}}
+\func{static wxConfigBase *}{Get}{\param{bool }{CreateOnDemand = TRUE}}
Get the current config object. If there is no current object and
{\it CreateOnDemand} is TRUE, creates one
\membersection{wxConfigBase::Set}\label{wxconfigbaseset}
-\func{wxConfigBase *}{Set}{\param{wxConfigBase *}{pConfig}}
+\func{static wxConfigBase *}{Set}{\param{wxConfigBase *}{pConfig}}
Sets the config object as the current one, returns the pointer to the previous
current object (both the parameter and returned value may be NULL)
