6ac7ddd3 27 program sources (it was previously required if you wanted to support Unicode).

36 Compatibility macro which expands to wxT() in wxWidgets 2 only.
37
c3b8a196
VZ
38 This macro can be used in code which needs to compile with both
39 wxWidgets 2 and 3 versions, in places where the wx2 API requires a Unicode string
40 (in Unicode build) but the wx3 API only accepts a standard narrow
41 string, as in e.g. wxCmdLineEntryDesc structure objects initializers.
9204fde6
VZ
42
43 Example of use:
44 @code
45 const wxCmdLineEntryDesc cmdLineDesc[] =
46 {
47 { wxCMD_LINE_SWITCH, wxT_2("q"), wxT_2("quiet"),
48 wxT_2("Don't output verbose messages") },
49 wxCMD_LINE_DESC_END
50 };
51 @endcode
52
c3b8a196
VZ
53 Without @c wxT_2 the code above wouldn't compile with wxWidgets 2, but using @c
54 wxT instead, it wouldn't compile with wxWidgets 3.

65 wxS is a macro which can be used with character and string literals (in other words,
66 @c 'x' or @c "foo") to convert them either to wide characters or wide strings
67 in @c wchar_t-based (UTF-16) builds, or to keep them unchanged in @c char-based
fde96a2f 68 (UTF-8) builds.

70 Basically this macro produces characters or strings of type wxStringCharType.
71
fde96a2f
FM
72 The use of this macro is optional as the translation will always be done at
73 run-time even if there is a mismatch between the kind of the literal used
74 and the string or character type used in the current build.
75 However using it can be beneficial in <b>performance-sensitive code</b> to
76 do the conversion at compile-time instead.

85 This macro is exactly the same as wxT() and is defined in wxWidgets simply
86 because it may be more intuitive for Windows programmers as the standard
87 Win32 headers also define it (as well as yet another name for the same
88 macro which is _TEXT()).
89
90 Don't confuse this macro with _()!

92 Note that since wxWidgets 2.9.0 the use of _T() is discouraged just like
93 for wxT() and also that this macro may conflict with identifiers defined in
94 standard headers of some compilers (such as Sun CC) so its use should
95 really be avoided.
