This macro simply returns the value passed to it without changes in ASCII build. In fact, its definition is: @code #ifdef UNICODE # define wxT(x) L##x #else // !Unicode # define wxT(x) x #endif @endcode Note that since wxWidgets 2.9.0 you shouldn't use wxT() anymore in your program sources if you want to support Unicode. @see @ref overview_unicode, wxS() @header{wx/chartype.h} */ #define wxT(string) /** wxS is macro which can be used with character and string literals (in other words, @c 'x' or @c "foo") to either convert them to wide characters or wide strings in @c wchar_t-based (UTF-16) builds or keep them unchanged in @c char-based (UTF-8) builds. Basically this macro produces characters or strings of type wxStringCharType. The use of this macro is optional as the translation will always be done at run-time even if there is a mismatch between the kind of the literal used and the string or character type used in the current build. However using it can be beneficial in performance-sensitive code to do the conversion at compile-time instead. @see @ref overview_unicode, wxT() @header{wx/chartype.h} */ #define wxS(string) /** This macro is exactly the same as wxT() and is defined in wxWidgets simply because it may be more intuitive for Windows programmers as the standard Win32 headers also define it (as well as yet another name for the same macro which is _TEXT()).
