-wxString is a class representing a character string. Please see wxString
-\helpref{overview}{wxstringoverview} for more information about it. As explained
-there, wxStrign implements about 90\% of methods of std::string class (iterators
-are not supported and so all methods which use them are not supported neither),

This section also contains both implicit and explicit conversions to C style
strings. Although implicit conversion is quite convenient, it is advised to use
explicit \helpref{c\_str()}{wxstringcstr} method for the sake of clarity. Also

+\membersection{Conversion to numbers}
+
+The string provides functions for conversion to signed and unsigned integer and
+floating point numbers. All three functions take a pointer to the variable to
+put the numeric value in and return TRUE if the {\bf entire} string could be
+converted to a number.

\constfunc{int}{CompareTo}{\param{const char*}{ psz}, \param{caseCompare}{ cmp = exact}}
Case-sensitive comparison. Returns 0 if equal, 1 if greater or -1 if less.
\func{void}{Empty}{\void}
