@class wxString
@wxheader{string.h}
- wxString is a class representing a character string. It uses
- reference counting and copy-on-write internally and is not
- thread-safe. Please see the
- @ref overview_string "wxString overview" and the
- @ref overview_unicode "Unicode overview" for more information
- about it.
-
+ wxString is a class representing a Unicode character string.
+ wxString uses @c std::string internally to store its content
+ unless this is not supported by the compiler or disabled
+ specifically when building wxWidgets. Therefore wxString
+ inherits many features from @c std::string's. Most
+ implementations of @std::string are thread-safe and don't
+ use reference counting. By default, wxString uses @c std::string
+ internally even if wxUSE_STL is not defined.
+
Since wxWidgets 3.0 wxString internally uses UCS-2 (basically 2-byte per
character wchar_t) under Windows and UTF-8 under Unix, Linux and
- OS X to store its content. Much work has been done to make
- existing code using ANSI string literals work as before.
+ OS X to store its content. Much work has been done to make existing
+ code using ANSI string literals work as before. If you need to have a
+ wxString that uses wchar_t on Unix and Linux, too, you can specify
+ this on the command line with the @c configure @c --disable-utf8 switch.
+
+ As a consequence of this change, iterating over a wxString by index
+ can become inefficient in UTF8 mode and iterators should be used instead:
+
+ @code
+ wxString s = "hello";
+ wxString::const_iterator i;
+ for (i = s.begin(); i != s.end(); ++i)
+ {
+ wxUniChar uni_ch = *i;
+ // do something with it
+ }
+ @endcode
- wxString implements most of the methods of the
- std::string class. These standard functions are not documented in
- this manual, please see the STL documentation. The behaviour of
- all these functions is identical to the behaviour described there.
+ Please see the
+ @ref overview_string "wxString overview" and the
+ @ref overview_unicode "Unicode overview" for more information
+ about it.
+
+ wxString uses the current locale encoding to convert any C string
+ literal to Unicode. The same is done for converting to and from
+ @c std::string and for the return value of c_str(). For this
+ conversion, the @a wxConvLibc class instance is used. See wxCSConv and wxMBConv.

+ wxString implements most of the methods of the @c std::string class.
+ These standard functions are only listed here, but they are not
+ fully documented in this manual. Please see the STL documentation.
+ 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, wxString::Length, wxString::Len and @c length()
- which all return the string length. In all cases of such duplication the @c std::string
- compatible method (@c length() in this case, always the lowercase version) should be
- used as it will ensure smoother transition to @c std::string when wxWidgets
- starts using it instead of wxString.
+ You may notice that wxString sometimes has several functions which do
+ the same thing like, for example, Length(), Len() and length() which
+ all return the string length. In all cases of such duplication the
+ @c std::string compatible method should be used.
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.

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
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 c_str() method for the sake of clarity.

The default comparison function Cmp() is case-sensitive and
so is the default version of IsSameAs(). For case
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 Cmp() does.

StartsWith() is helpful when parsing a line of text which should start
with some predefined prefix and is more efficient than doing direct string
