\section{\class{wxString}}\label{wxstring}
-\overview{Overview}{wxstringoverview}
+wxString is a class representing a character string. Please see the
+\helpref{wxString overview}{wxstringoverview} for more information about it.
-\helpref{Member functions by category}{wxstringcategories}
+As explained there, wxString implements most of the methods of the std::string
+class.
+These standard functions are not documented in this manual, please see the
+\urlref{STL documentation}{http://www.cppreference.com/cppstl.html}).
+The behaviour of all these functions is identical to the behaviour described
+there.
+
+You may notice that wxString sometimes has many functions which do the same
+thing like, for example, \helpref{Length()}{wxstringlength},
+\helpref{Len()}{wxstringlen} and {\tt length()} which all return the string
+length. In all cases of such duplication the {\tt std::string}-compatible
+method ({\tt length()} in this case, always the lowercase version) should be
+used as it will ensure smoother transition to {\tt std::string} when wxWidgets
+starts using it instead of wxString.

+\membersection{Constructors and assignment operators}\label{constructorsinwxstring}
+
+A string may be constructed either from a C string, (some number of copies of)
+a single character or a wide (UNICODE) string. For all constructors (except the
+default which creates an empty string) there is also a corresponding assignment
+operator.
+
+\helpref{wxString}{wxstringconstruct}\\
+\helpref{operator $=$}{wxstringoperatorassign}\\
+\helpref{\destruct{wxString}}{wxstringdestruct}
+
+
+\membersection{String length}\label{lengthfunctionsinwxstring}
+
+These functions return the string length and check whether the string is empty
+or empty it.
+
+\helpref{Len}{wxstringlen}\\
+\helpref{IsEmpty}{wxstringisempty}\\
+\helpref{operator!}{wxstringoperatornot}\\
+\helpref{Empty}{wxstringempty}\\
+\helpref{Clear}{wxstringclear}
+
+
+\membersection{Character access}\label{characteraccessinwxstring}
+
+Many functions in this section take a character index in the string. As with C
+strings and/or arrays, the indices start from $0$, so the first character of a
+string is string[$0$]. Attempt to access a character beyond the end of the
+string (which may be even $0$ if the string is empty) will provoke an assert
+failure in \helpref{debug build}{debuggingoverview}, but no checks are done in
+release builds.
+
+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
+see \helpref{overview}{wxstringadvices} for the cases where it is necessary to
+use it.

+\helpref{wc\_str}{wxstringwcstr}\\
+\helpref{fn\_str}{wxstringfnstr}\\
+\helpref{operator const char*}{wxstringoperatorconstcharpt}
+
+
+\membersection{Concatenation}\label{concatenationinwxstring}
+
+Anything may be concatenated (appended to) with a string. However, you can't
+append something to a C string (including literal constants), so to do this it
+should be converted to a wxString first.
+
+\helpref{operator \cinsert}{wxstringoperatorout}\\
+\helpref{operator $+=$}{wxstringplusequal}\\
+\helpref{operator $+$}{wxstringoperatorplus}\\
+\helpref{Append}{wxstringappend}\\
+\helpref{Prepend}{wxstringprepend}
+
+
+\membersection{Comparison}\label{comparisoninwxstring}
+
+The default comparison function \helpref{Cmp}{wxstringcmp} is case-sensitive and
+so is the default version of \helpref{IsSameAs}{wxstringissameas}. For case
+insensitive comparisons you should use \helpref{CmpNoCase}{wxstringcmpnocase} or
+give a second parameter to IsSameAs. This last function is may be more
+convenient if only equality of the strings matters because it returns a boolean
+\true value if the strings are the same and not 0 (which is usually false in C)
+as {\tt Cmp()} does.
+
+\helpref{Matches}{wxstringmatches} is a poor man's regular expression matcher:
+it only understands '*' and '?' metacharacters in the sense of DOS command line
+interpreter.
+
+\helpref{StartsWith}{wxstringstartswith} is helpful when parsing a line of
+text which should start with some predefined prefix and is more efficient than
+doing direct string comparison as you would also have to precalculate the
+length of the prefix then.
+
+\helpref{Cmp}{wxstringcmp}\\
+\helpref{CmpNoCase}{wxstringcmpnocase}\\
+\helpref{IsSameAs}{wxstringissameas}\\
+\helpref{Matches}{wxstringmatches}\\
+\helpref{StartsWith}{wxstringstartswith}\\
+\helpref{EndsWith}{wxstringendswith}
+
+
+\membersection{Substring extraction}\label{substringextractioninwxstring}
+
+These functions allow to extract substring from this string. All of them don't
+modify the original string and return a new string containing the extracted
+substring.
+
+\helpref{Mid}{wxstringmid}\\
+\helpref{operator()}{wxstringoperatorparenth}\\
+\helpref{Left}{wxstringleft}\\
+\helpref{Right}{wxstringright}\\
+\helpref{BeforeFirst}{wxstringbeforefirst}\\
+\helpref{BeforeLast}{wxstringbeforelast}\\
+\helpref{AfterFirst}{wxstringafterfirst}\\
+\helpref{AfterLast}{wxstringafterlast}\\
+\helpref{StartsWith}{wxstringstartswith}\\
+\helpref{EndsWith}{wxstringendswith}
+
+
+
+\membersection{Case conversion}\label{caseconversioninwxstring}
+
+The MakeXXX() variants modify the string in place, while the other functions
+return a new string which contains the original text converted to the upper or
+lower case and leave the original string unchanged.
+
+\helpref{MakeUpper}{wxstringmakeupper}\\
+\helpref{Upper}{wxstringupper}\\
+\helpref{MakeLower}{wxstringmakelower}\\
+\helpref{Lower}{wxstringlower}
+
+
+\membersection{Searching and replacing}\label{searchingandreplacinginwxstring}
+
+These functions replace the standard {\it strchr()} and {\it strstr()}
+functions.
+
+\helpref{Find}{wxstringfind}\\
+\helpref{Replace}{wxstringreplace}
+
+
+\membersection{Conversion to numbers}\label{conversiontonumbersinwxstring}
+
+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.
+
+\helpref{ToLong}{wxstringtolong}\\
+\helpref{ToLongLong}{wxstringtolonglong}\\
+\helpref{ToULong}{wxstringtoulong}\\
+\helpref{ToULongLong}{wxstringtoulonglong}\\
+\helpref{ToDouble}{wxstringtodouble}
+
+
+\membersection{Writing values into the string}\label{writingintostringinwxstring}
+
+Both formatted versions (\helpref{Printf}{wxstringprintf}) and stream-like
+insertion operators exist (for basic types only). Additionally, the
+\helpref{Format}{wxstringformat} function allows to use simply append
+formatted value to a string:
+
+\begin{verbatim}
+ // the following 2 snippets are equivalent
+
+ wxString s = "...";
+ s += wxString::Format("%d", n);
+
+ wxString s;
+ s.Printf("...%d", n);
+\end{verbatim}
+
+\helpref{Format}{wxstringformat}\\
+\helpref{FormatV}{wxstringformatv}\\
+\helpref{Printf}{wxstringprintf}\\
+\helpref{PrintfV}{wxstringprintfv}\\
+\helpref{operator \cinsert}{wxstringoperatorout}
+
+
+\membersection{Memory management}\label{memoryinwxstring}
+
+These are "advanced" functions and they will be needed quite rarely.
+\helpref{Alloc}{wxstringalloc} and \helpref{Shrink}{wxstringshrink} are only
+interesting for optimization purposes.
+\helpref{GetWriteBuf}{wxstringgetwritebuf} may be very useful when working with
+some external API which requires the caller to provide a writable buffer, but
+extreme care should be taken when using it: before performing any other
+operation on the string \helpref{UngetWriteBuf}{wxstringungetwritebuf} {\bf
+must} be called!
+
+\helpref{Alloc}{wxstringalloc}\\
+\helpref{Shrink}{wxstringshrink}\\
+\helpref{GetWriteBuf}{wxstringgetwritebuf}\\
+\helpref{UngetWriteBuf}{wxstringungetwritebuf}
+
+
+\membersection{Miscellaneous}\label{miscellaneousinwxstring}
+
+Other string functions.
+
+\helpref{Trim}{wxstringtrim}\\
+\helpref{Truncate}{wxstringtruncate}\\
+\helpref{Pad}{wxstringpad}
+
+
+\membersection{wxWidgets 1.xx compatibility functions}\label{backwardcompatibilityinwxstring}
+
+These functions are deprecated, please consider using new wxWidgets 2.0
+functions instead of them (or, even better, std::string compatible variants).

+\func{}{wxString}{\void}
+
+Default constructor. Initializes the string to {\tt ""} (empty string).
+
+\func{}{wxString}{\param{const wxString\&}{ x}}
+
+Copy constructor.
+
+\func{}{wxString}{\param{wxChar}{ ch}, \param{size\_t}{ n = 1}}
+
+Constructs a string of {\it n} copies of character {\it ch}.
+
+\func{}{wxString}{\param{const wxChar*}{ psz}, \param{size\_t}{ nLength = wxSTRING\_MAXLEN}}
+
+Takes first {\it nLength} characters from the C string {\it psz}.
+The default value of {\tt wxSTRING\_MAXLEN} means to take all the string.
+
+Note that this constructor may be used even if {\it psz} points to a buffer
+with binary data (i.e. containing {\tt NUL} characters) as long as you provide
+the correct value for {\it nLength}. However, the default form of it works
+only with strings without intermediate {\tt NUL}s because it uses
+{\tt strlen()} to calculate the effective length and it would not give correct
+results otherwise.
+
+\func{}{wxString}{\param{const unsigned char*}{ psz}, \param{size\_t}{ nLength = wxSTRING\_MAXLEN}}
+
+For compilers using unsigned char: takes first {\it nLength} characters from the C string {\it psz}.
+The default value of {\tt wxSTRING\_MAXLEN} means take all the string.
+For ANSI builds only (note the use of {\tt char} instead of {\tt wxChar}).
+
+\wxheading{Constructors with conversion}
+
+The following constructors allow you to construct wxString from a wide string
+in ANSI build or from a C string in Unicode build.
+
+\func{}{wxString}{\param{const wchar\_t*}{ psz}, \param{wxMBConv\&}{ conv}, \param{size\_t}{ nLength = wxSTRING\_MAXLEN}}
+
+Initializes the string from first \arg{nLength} characters of wide string.
+The default value of {\tt wxSTRING\_MAXLEN} means take all the string.
+In ANSI build, \arg{conv}'s
+\helpref{WC2MB}{wxmbconvwc2mb} method is called to
+convert \arg{psz} to wide string. It is ignored in Unicode build.
+
+\func{}{wxString}{\param{const char*}{ psz}, \param{wxMBConv\&}{ conv}, \param{size\_t}{ nLength = wxSTRING\_MAXLEN}}
+
+Initializes the string from first \arg{nLength} characters of C string.
+The default value of {\tt wxSTRING\_MAXLEN} means take all the string.
+In Unicode build, \arg{conv}'s
+\helpref{MB2WC}{wxmbconvmb2wc} method is called to
+convert \arg{psz} to wide string. It is ignored in ANSI build.

+\func{}{\destruct{wxString}}{\void}
+
+String destructor. Note that this is not virtual, so wxString must not be inherited from.
+
+
+\membersection{wxString::Alloc}\label{wxstringalloc}
-String destructor.
+\func{void}{Alloc}{\param{size\_t}{ nLen}}
+
+Preallocate enough space for wxString to store {\it nLen} characters. This function
+may be used to increase speed when the string is constructed by repeated
+concatenation as in
+
+\begin{verbatim}
-\membersection{wxString::Alloc}\label{wxstringAlloc}

+ result += original[n];
+ }
+
+ return result;
+}
+
+\end{verbatim}
-\func{void}{Alloc}{\param{int}{ newsize}}
+because it will avoid the need to reallocate string memory many times (in case
+of long strings). Note that it does not set the maximal length of a string - it
+will still expand if more than {\it nLen} characters are stored in it. Also, it
+does not truncate the existing string (use
+\helpref{Truncate()}{wxstringtruncate} for this) even if its current length is
+greater than {\it nLen}

-wxSubString extraction.

+Prepends {\it str} to this string, returning a reference to this string.
-Formatted assignment. We do not use the 'sprintf' constructor anymore,
-because with that constructor, every initialisation with a string would
-go through sprintf and this is not desirable, because sprintf

+
+\membersection{wxString::Printf}\label{wxstringprintf}
+
+\func{int}{Printf}{\param{const wxChar* }{pszFormat}, \param{}{...}}
+
+Similar to the standard function {\it sprintf()}. Returns the number of
+characters written, or an integer less than zero on error.
+
+Note that if {\tt wxUSE\_PRINTF\_POS\_PARAMS} is set to 1, then this function supports
+Unix98-style positional parameters:
\begin{verbatim}
-wxString msg; msg.sprintf("Processing item %d\n", count);

\end{verbatim}
-\membersection{wxString::Strip}\label{wxstringStrip}
+{\bf NB:} This function will use a safe version of {\it vsprintf()} (usually called

+\membersection{wxString::Shrink}\label{wxstringshrink}
+
+\func{void}{Shrink}{\void}

+
+
+\membersection{wxString::StartsWith}\label{wxstringstartswith}
+
+\constfunc{bool}{StartsWith}{\param{const wxChar }{*prefix}, \param{wxString }{*rest = NULL}}
+
+This function can be used to test if the string starts with the specified
+{\it prefix}. If it does, the function will return \true and put the rest
+of the string (i.e. after the prefix) into {\it rest} string if it is not
+{\tt NULL}. Otherwise, the function returns \false and doesn't modify the
+{\it rest}.
+
+
+\membersection{wxString::EndsWith}\label{wxstringendswith}
+
+\constfunc{bool}{EndsWith}{\param{const wxChar }{*suffix}, \param{wxString }{*rest = NULL}}
+
+This function can be used to test if the string ends with the specified
+{\it suffix}. If it does, the function will return \true and put the
+beginning of the string before the suffix into {\it rest} string if it is not
+{\tt NULL}. Otherwise, the function returns \false and doesn't

-\func{wxSubString}{Strip}{\param{StripType}{ s = trailing}, \param{char}{ c = ' '}}
+\constfunc{wxString}{Strip}{\param{stripType}{ s = trailing}}
+
+Strip characters at the front and/or end. The same as Trim except that it
+doesn't change this string.
+
+This is a wxWidgets 1.xx compatibility function; you should not use it in new code.
+
+
+\membersection{wxString::SubString}\label{wxstringsubstring}
+
+\constfunc{wxString}{SubString}{\param{size\_t}{ from}, \param{size\_t}{ to}}
+
+Returns the part of the string between the indices {\it from} and {\it to}
+inclusive.
+
+This is a wxWidgets 1.xx compatibility function, use \helpref{Mid}{wxstringmid}
+instead (but note that parameters have different meaning).
+
+
+\membersection{wxString::ToAscii}\label{wxstringtoascii}
+
+\constfunc{const char*}{ToAscii}{\void}
+
+Converts the string to an ASCII, 7-bit string (ANSI builds only).
+
+\constfunc{const wxCharBuffer}{ToAscii}{\void}
+
+Converts the string to an ASCII, 7-bit string in the form of
+a wxCharBuffer (Unicode builds only).
+
+Note that this conversion only works if the string contains only ASCII
+characters. The \helpref{mb\_str}{wxstringmbstr} method provides more

+
+
+\membersection{wxString::ToDouble}\label{wxstringtodouble}
+
+\constfunc{bool}{ToDouble}{\param{double}{ *val}}
+
+Attempts to convert the string to a floating point number. Returns \true on

+\constfunc{bool}{ToLong}{\param{long}{ *val}, \param{int }{base = $10$}}
+
+Attempts to convert the string to a signed integer in base {\it base}. Returns
+\true on success in which case the number is stored in the location
+pointed to by {\it val} or \false if the string does not represent a
+valid number in the given base.
+
+The value of {\it base} must be comprised between $2$ and $36$, inclusive, or
+be a special value $0$ which means that the usual rules of {\tt C} numbers are
+applied: if the number starts with {\tt 0x} it is considered to be in base
+$16$, if it starts with {\tt 0} - in base $8$ and in base $10$ otherwise. Note
+that you may not want to specify the base $0$ if you are parsing the numbers
+which may have leading zeroes as they can yield unexpected (to the user not
+familiar with C) results.

+
+Notice that currently it doesn't work (always returns \false) if parsing of 64

+Attempts to convert the string to an unsigned integer in base {\it base}.
+Returns \true on success in which case the number is stored in the
+location pointed to by {\it val} or \false if the string does not
+represent a valid number in the given base. Please notice that this function
+behaves in the same way as the standard \texttt{strtoul()} and so it simply
+converts negative numbers to unsigned representation instead of rejecting them
+(e.g. $-1$ is returned as \texttt{ULONG\_MAX}).

+Puts the string back into a reasonable state (in which it can be used
+normally), after
+\rtfsp\helpref{wxString::GetWriteBuf}{wxstringgetwritebuf} was called.
+
+The version of the function without the {\it len} parameter will calculate the
+new string length itself assuming that the string is terminated by the first
+{\tt NUL} character in it while the second one will use the specified length
+and thus is the only version which should be used with the strings with

+
+This tiny class allows to conveniently access the \helpref{wxString}{wxstring}
+internal buffer as a writable pointer without any risk of forgetting to restore
+the string to the usable state later.
+
+For example, assuming you have a low-level OS function called
+{\tt GetMeaningOfLifeAsString(char *)} returning the value in the provided
+buffer (which must be writable, of course) you might call it like this:
\begin{verbatim}
-#define wxCHARARG(s) ((const wxString\& )(s).Chars())
+ wxString theAnswer;
+ GetMeaningOfLifeAsString(wxStringBuffer(theAnswer, 1024));
+ if ( theAnswer != "42" )
+ {
+ wxLogError("Something is very wrong!");
+ }
\end{verbatim}
-Here is a very, very, very ugly macro, but it makes things more
-transparent in cases, where a library function requires a
-(const wxString\& ) argument. This is especially the case in wxWindows,
-where all char-arguments are (const wxString\& ) and not (const char* ).
-This macro should only be used in such cases and NOT to
-modify the internal data.
-The conventional way would be 'function((char*)string.Chars())'.
-With the wxCHARARG macro, this can be achieved by 'function(wxCHARARG(string))'.
-This makes it clearer that the usage should be confined
-to arguments.

+Note that the exact usage of this depends on whether on not wxUSE\_STL is enabled. If
+wxUSE\_STL is enabled, wxStringBuffer creates a separate empty character buffer, and
+if wxUSE\_STL is disabled, it uses GetWriteBuf() from wxString, keeping the same buffer
+wxString uses intact. In other words, relying on wxStringBuffer containing the old
+wxString data is probably not a good idea if you want to build your program in both
+with and without wxUSE\_STL.

+\membersection{wxStringBuffer::wxStringBuffer}\label{wxstringbufferctor}
+
+\func{}{wxStringBuffer}{\param{const wxString\& }{str}, \param{size\_t }{len}}
+
+Constructs a writable string buffer object associated with the given string
+and containing enough space for at least {\it len} characters. Basically, this
+is equivalent to calling \helpref{GetWriteBuf}{wxstringgetwritebuf} and
+saving the result.
+
+
+\membersection{wxStringBuffer::\destruct{wxStringBuffer}}\label{wxstringbufferdtor}

+\func{}{\destruct{wxStringBuffer}}{\void}
+
+Restores the string passed to the constructor to the usable state by calling
+\helpref{UngetWriteBuf}{wxstringungetwritebuf} on it.
+
+
+\membersection{wxStringBuffer::operator wxChar *}\label{wxstringbufferwxchar}
+
+\func{wxChar *}{operator wxChar *}{\void}
+
+Returns the writable pointer to a buffer of the size at least equal to the
+length specified in the constructor.
+
+
+
+\section{\class{wxStringBufferLength}}\label{wxstringbufferlength}
+
+This tiny class allows to conveniently access the \helpref{wxString}{wxstring}
+internal buffer as a writable pointer without any risk of forgetting to restore
+the string to the usable state later, and allows the user to set the internal
+length of the string.
+
+For example, assuming you have a low-level OS function called
+{\tt int GetMeaningOfLifeAsString(char *)} copying the value in the provided
+buffer (which must be writable, of course), and returning the actual length
+of the string, you might call it like this:
+
+\begin{verbatim}
+ wxString theAnswer;
+ wxStringBuffer theAnswerBuffer(theAnswer, 1024);
+ int nLength = GetMeaningOfLifeAsString(theAnswerBuffer);
+ theAnswerBuffer.SetLength(nLength);
+ if ( theAnswer != "42" )
+ {
+ wxLogError("Something is very wrong!");
+ }
+\end{verbatim}
+
+Note that the exact usage of this depends on whether on not wxUSE\_STL is enabled. If
+wxUSE\_STL is enabled, wxStringBuffer creates a separate empty character buffer, and
+if wxUSE\_STL is disabled, it uses GetWriteBuf() from wxString, keeping the same buffer
+wxString uses intact. In other words, relying on wxStringBuffer containing the old
+wxString data is probably not a good idea if you want to build your program in both
+with and without wxUSE\_STL.
+
+Note that SetLength {\tt must} be called before wxStringBufferLength destructs.
