\membersection{wxConfigBase::\destruct{wxConfigBase}}\label{wxconfigbasedtor}

\func{}{\destruct{wxConfigBase}}{\void}

Empty but ensures that dtor of all derived classes is virtual.


\membersection{wxConfigBase::Create}\label{wxconfigbasecreate}

\func{static wxConfigBase *}{Create}{\void}

Create a new config object: this function will create the "best"
implementation of wxConfig available for the current platform, see comments
near the definition of wxCONFIG\_WIN32\_NATIVE for details. It returns the
created object and also sets it as the current one.


\membersection{wxConfigBase::DontCreateOnDemand}\label{wxconfigbasedontcreateondemand}

\func{void}{DontCreateOnDemand}{\void}

Calling this function will prevent {\it Get()} from automatically creating a
new config object if the current one is NULL. It might be useful to call it
near the program end to prevent "accidental" creation of a new config object.


\membersection{wxConfigBase::DeleteAll}\label{wxconfigbasedeleteall}

\func{bool}{DeleteAll}{\void}

Delete the whole underlying object (disk file, registry key, ...). Primarly
for use by uninstallation routine.


\membersection{wxConfigBase::DeleteEntry}\label{wxconfigbasedeleteentry}

\func{bool}{DeleteEntry}{\param{const wxString\& }{ key}, \param{bool}{ bDeleteGroupIfEmpty = true}}

Deletes the specified entry and the group it belongs to if it was the last key
in it and the second parameter is true.


\membersection{wxConfigBase::DeleteGroup}\label{wxconfigbasedeletegroup}

\func{bool}{DeleteGroup}{\param{const wxString\& }{ key}}

Delete the group (with all subgroups). If the current path is under the group
being deleted it is changed to its deepest still existing component. E.g. if
the current path is \texttt{/A/B/C/D} and the group \texttt{C} is deleted the
path becomes \texttt{/A/B}.


\membersection{wxConfigBase::Exists}\label{wxconfigbaseexists}

\constfunc{bool}{Exists}{\param{wxString\& }{strName}}

returns \true if either a group or an entry with a given name exists


\membersection{wxConfigBase::Flush}\label{wxconfigbaseflush}

\func{bool}{Flush}{\param{bool }{bCurrentOnly = false}}

permanently writes all changes (otherwise, they're only written from object's
destructor)


\membersection{wxConfigBase::Get}\label{wxconfigbaseget}

\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
(using {\it Create}) unless DontCreateOnDemand was called previously.


\membersection{wxConfigBase::GetAppName}\label{wxconfigbasegetappname}

\constfunc{wxString}{GetAppName}{\void}

Returns the application name.


\membersection{wxConfigBase::GetEntryType}\label{wxconfigbasegetentrytype}

\constfunc{enum wxConfigBase::EntryType}{GetEntryType}{\param{const wxString\& }{name}}

Returns the type of the given entry or {\it Unknown} if the entry doesn't
exist. This function should be used to decide which version of Read() should
be used because some of wxConfig implementations will complain about type
mismatch otherwise: e.g., an attempt to read a string value from an integer
key with wxRegConfig will fail.

The result is an element of enum EntryType:

\begin{verbatim}
  enum EntryType
  {
    Type_Unknown,
    Type_String,
    Type_Boolean,
    Type_Integer,
    Type_Float
  };
\end{verbatim}


\membersection{wxConfigBase::GetFirstGroup}\label{wxconfigbasegetfirstgroup}

\constfunc{bool}{GetFirstGroup}{\param{wxString\& }{str}, \param{long\&}{ index}}

Gets the first group.

\pythonnote{The wxPython version of this method returns a 3-tuple
consisting of the continue flag, the value string, and the index for
the next call.}

\perlnote{In wxPerl this method takes no arguments and returns a 3-element
list {\tt ( continue, str, index )}.}


\membersection{wxConfigBase::GetFirstEntry}\label{wxconfigbasegetfirstentry}

\constfunc{bool}{GetFirstEntry}{\param{wxString\& }{str}, \param{long\&}{ index}}

Gets the first entry.

\pythonnote{The wxPython version of this method returns a 3-tuple
consisting of the continue flag, the value string, and the index for
the next call.}

\perlnote{In wxPerl this method takes no arguments and returns a 3-element
list {\tt ( continue, str, index )}.}


\membersection{wxConfigBase::GetNextGroup}\label{wxconfigbasegetnextgroup}

\constfunc{bool}{GetNextGroup}{\param{wxString\& }{str}, \param{long\&}{ index}}

Gets the next group.

\pythonnote{The wxPython version of this method returns a 3-tuple
consisting of the continue flag, the value string, and the index for
the next call.}

\perlnote{In wxPerl this method only takes the {\tt index} parameter
and returns a 3-element list {\tt ( continue, str, index )}.}


\membersection{wxConfigBase::GetNextEntry}\label{wxconfigbasegetnextentry}

\constfunc{bool}{GetNextEntry}{\param{wxString\& }{str}, \param{long\&}{ index}}

Gets the next entry.

\pythonnote{The wxPython version of this method returns a 3-tuple
consisting of the continue flag, the value string, and the index for
the next call.}

\perlnote{In wxPerl this method only takes the {\tt index} parameter
and returns a 3-element list {\tt ( continue, str, index )}.}


\membersection{wxConfigBase::GetNumberOfEntries}\label{wxconfigbasegetnumberofentries}

\constfunc{uint }{GetNumberOfEntries}{\param{bool }{bRecursive = false}}


\membersection{wxConfigBase::GetNumberOfGroups}\label{wxconfigbasegetnumberofgroups}

\constfunc{uint}{GetNumberOfGroups}{\param{bool }{bRecursive = false}}

Get number of entries/subgroups in the current group, with or without its
subgroups.


\membersection{wxConfigBase::GetPath}\label{wxconfigbasegetpath}

\constfunc{const wxString\&}{GetPath}{\void}

Retrieve the current path (always as absolute path).


\membersection{wxConfigBase::GetVendorName}\label{wxconfigbasegetvendorname}

\constfunc{wxString}{GetVendorName}{\void}

Returns the vendor name.


\membersection{wxConfigBase::HasEntry}\label{wxconfigbasehasentry}

\constfunc{bool}{HasEntry}{\param{wxString\& }{strName}}

returns \true if the entry by this name exists


\membersection{wxConfigBase::HasGroup}\label{wxconfigbasehasgroup}

\constfunc{bool}{HasGroup}{\param{const wxString\& }{strName}}

returns \true if the group by this name exists


\membersection{wxConfigBase::IsExpandingEnvVars}\label{wxconfigbaseisexpandingenvvars}

\constfunc{bool}{IsExpandingEnvVars}{\void}

Returns \true if we are expanding environment variables in key values.


\membersection{wxConfigBase::IsRecordingDefaults}\label{wxconfigbaseisrecordingdefaults}

\constfunc{bool}{IsRecordingDefaults}{\void}

Returns \true if we are writing defaults back to the config file.


\membersection{wxConfigBase::Read}\label{wxconfigbaseread}

\constfunc{bool}{Read}{\param{const wxString\& }{key}, \param{wxString*}{ str}}

Read a string from the key, returning \true if the value was read. If the key
was not found, {\it str} is not changed.

\constfunc{bool}{Read}{\param{const wxString\& }{key}, \param{wxString*}{ str}, \param{const wxString\& }{defaultVal}}

Read a string from the key. The default value is returned if the key was not
found.

Returns \true if value was really read, \false if the default was used.

\constfunc{wxString}{Read}{\param{const wxString\& }{key}, \param{const
wxString\& }{defaultVal}}

Another version of {\it Read()}, returning the string value directly.

\constfunc{bool}{Read}{\param{const wxString\& }{ key}, \param{long*}{ l}}

Reads a long value, returning \true if the value was found. If the value was
not found, {\it l} is not changed.

\constfunc{bool}{Read}{\param{const wxString\& }{ key}, \param{long*}{ l},
\param{long}{ defaultVal}}

Reads a long value, returning \true if the value was found. If the value was
not found, {\it defaultVal} is used instead.

\constfunc{long }{Read}{\param{const wxString\& }{key}, \param{long}{ defaultVal}}

Reads a long value from the key and returns it. {\it defaultVal} is returned
if the key is not found.

NB: writing

{\small
\begin{verbatim}
    conf->Read("key", 0);
\end{verbatim}
}

won't work because the call is ambiguous: compiler can not choose between two
{\it Read} functions. Instead, write:

{\small
\begin{verbatim}
    conf->Read("key", 0l);
\end{verbatim}
}

\constfunc{bool}{Read}{\param{const wxString\& }{ key}, \param{double*}{ d}}

Reads a double value, returning \true if the value was found. If the value was
not found, {\it d} is not changed.

\constfunc{bool}{Read}{\param{const wxString\& }{ key}, \param{double*}{ d},
 \param{double}{ defaultVal}}

Reads a double value, returning \true if the value was found. If the value was
not found, {\it defaultVal} is used instead.

\constfunc{bool}{Read}{\param{const wxString\& }{ key}, \param{bool*}{ b}}

Reads a bool value, returning \true if the value was found. If the value was
not found, {\it b} is not changed.

\constfunc{bool}{Read}{\param{const wxString\& }{ key}, \param{bool*}{ d},
\param{bool}{ defaultVal}}

Reads a bool value, returning \true if the value was found. If the value was
not found, {\it defaultVal} is used instead.

implements the following methods:\par
\indented{2cm}{\begin{twocollist}

}}


\membersection{wxConfigBase::RenameEntry}\label{wxconfigbaserenameentry}

\func{bool}{RenameEntry}{\param{const wxString\& }{ oldName}, \param{const wxString\& }{ newName}}

Renames an entry in the current group. The entries names (both the old and
the new one) shouldn't contain backslashes, i.e. only simple names and not
arbitrary paths are accepted by this function.

Returns \false if {\it oldName} doesn't exist or if {\it newName} already
exists.


\membersection{wxConfigBase::RenameGroup}\label{wxconfigbaserenamegroup}

\func{bool}{RenameGroup}{\param{const wxString\& }{ oldName}, \param{const wxString\& }{ newName}}

Renames a subgroup of the current group. The subgroup names (both the old and
the new one) shouldn't contain backslashes, i.e. only simple names and not
arbitrary paths are accepted by this function.

Returns \false if {\it oldName} doesn't exist or if {\it newName} already
exists.


\membersection{wxConfigBase::Set}\label{wxconfigbaseset}

\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)


\membersection{wxConfigBase::SetExpandEnvVars}\label{wxconfigbasesetexpandenvvars}

\func{void}{SetExpandEnvVars }{\param{bool }{bDoIt = true}}

Determine whether we wish to expand environment variables in key values.


\membersection{wxConfigBase::SetPath}\label{wxconfigbasesetpath}

\func{void}{SetPath}{\param{const wxString\& }{strPath}}

Set current path: if the first character is '/', it is the absolute path,
otherwise it is a relative path. '..' is supported. If strPath doesn't
exist it is created.


\membersection{wxConfigBase::SetRecordDefaults}\label{wxconfigbasesetrecorddefaults}

\func{void}{SetRecordDefaults}{\param{bool }{bDoIt = true}}

Sets whether defaults are recorded to the config file whenever an attempt to
read the value which is not present in it is done.

If on (default is off) all default values for the settings used by the program
are written back to the config file. This allows the user to see what config
options may be changed and is probably useful only for wxFileConfig.


\membersection{wxConfigBase::Write}\label{wxconfigbasewrite}

\func{bool}{Write}{\param{const wxString\& }{ key}, \param{const wxString\& }{
value}}

\func{bool}{Write}{\param{const wxString\& }{ key}, \param{long}{ value}}

\func{bool}{Write}{\param{const wxString\& }{ key}, \param{double}{ value}}

\func{bool}{Write}{\param{const wxString\& }{ key}, \param{bool}{ value}}

These functions write the specified value to the config file and return \true on success.
