445 Virtual keycodes used by wxKeyEvent and some other wxWidgets functions.

895 /** @addtogroup group_funcmacro_byteorder */
899 This macro will swap the bytes of the @a value variable from little endian
900 to big endian or vice versa if the program is compiled on a little-endian
901 architecture (such as Intel PCs). If the program has been compiled on a
902 big-endian architecture, the value will be unchanged.
904 Use these macros to read data from and write data to a file that stores
905 data in big-endian format.

918 /** @addtogroup group_funcmacro_misc */
922 This macro can be used in a class declaration to disable the generation of
923 default assignment operator.
925 Some classes have a well-defined copy constructor but cannot have an
926 assignment operator, typically because they can't be modified once created.
927 In such case, this macro can be used to disable the automatic assignment
930 @see DECLARE_NO_COPY_CLASS()
932 #define DECLARE_NO_ASSIGN_CLASS(classname)
935 This macro can be used in a class declaration to disable the generation of
936 default copy ctor and assignment operator.
938 Some classes don't have a well-defined copying semantics. In this case the
939 standard C++ convention is to not allow copying them. One way of achieving
940 it is to use this macro which simply defines a private copy constructor and
943 Beware that simply not defining copy constructor and assignment operator is
944 @em not enough as the compiler would provide its own automatically-generated
945 versions of them -- hence the usefulness of this macro.
956 // widgets can't be copied
957 DECLARE_NO_COPY_CLASS(FooWidget)
961 Notice that a semicolon should not be used after this macro and that it
962 changes the access specifier to private internally so it is better to use
963 it at the end of the class declaration.
965 #define DECLARE_NO_COPY_CLASS(classname)
968 Equivalent of DECLARE_NO_COPY_CLASS() for template classes.
970 This macro can be used for template classes (with a single template
971 parameter) for the same purpose as DECLARE_NO_COPY_CLASS() is used with the
972 non-template classes.
974 @param classname The name of the template class.
975 @param arg The name of the template parameter.
977 #define DECLARE_NO_COPY_TEMPLATE_CLASS(classname, arg)
980 A function which deletes and nulls the pointer.
982 This function uses operator delete to free the pointer and also sets it to
983 @NULL. Notice that this does @em not work for arrays, use wxDELETEA() for
987 MyClass *ptr = new MyClass;
995 template <typename T
> wxDELETE(T
*& ptr
);
998 A function which deletes and nulls the pointer.
1000 This function uses vector operator delete (@c delete[]) to free the array
1001 pointer and also sets it to @NULL. Notice that this does @em not work for
1002 non-array pointers, use wxDELETE() for them.
1005 MyClass *array = new MyClass[17];
1015 template <typename T
> wxDELETEA(T
*& array
);
1018 This macro can be used around a function declaration to generate warnings
1019 indicating that this function is deprecated (i.e. obsolete and planned to
1020 be removed in the future) when it is used. Only Visual C++ 7 and higher and
1021 g++ compilers currently support this functionality.
1026 // old function, use wxString version instead
1027 wxDEPRECATED( void wxGetSomething(char *buf, size_t len) );
1030 wxString wxGetSomething();
1035 #define wxDEPRECATED(function)
1038 This is a special version of wxDEPRECATED() macro which only does something
1039 when the deprecated function is used from the code outside wxWidgets itself
1040 but doesn't generate warnings when it is used from wxWidgets.
1042 It is used with the virtual functions which are called by the library
1043 itself -- even if such function is deprecated the library still has to call
1044 it to ensure that the existing code overriding it continues to work, but
1045 the use of this macro ensures that a deprecation warning will be generated
1046 if this function is used from the user code or, in case of Visual C++, even
1047 when it is simply overridden.
1051 #define wxDEPRECATED_BUT_USED_INTERNALLY(function)
1054 This macro is similar to wxDEPRECATED() but can be used to not only declare
1055 the function @a function as deprecated but to also provide its (inline)
1056 implementation @a body.
1058 It can be used as following:
1064 // OldMethod() is deprecated, use NewMethod() instead
1066 wxDEPRECATED_INLINE( void OldMethod(), NewMethod() );
1072 #define wxDEPRECATED_INLINE(func, body)
1075 @c wxEXPLICIT is a macro which expands to the C++ @c explicit keyword if
1076 the compiler supports it or nothing otherwise. Thus, it can be used even in
1077 the code which might have to be compiled with an old compiler without
1078 support for this language feature but still take advantage of it when it is
1086 GNU C++ compiler gives a warning for any class whose destructor is private
1087 unless it has a friend. This warning may sometimes be useful but it doesn't
1088 make sense for reference counted class which always delete themselves
1089 (hence destructor should be private) but don't necessarily have any
1090 friends, so this macro is provided to disable the warning in such case. The
1091 @a name parameter should be the name of the class but is only used to
1092 construct a unique friend class name internally.
1094 Example of using the macro:
1100 RefCounted() { m_nRef = 1; }
1101 void IncRef() { m_nRef++ ; }
1102 void DecRef() { if ( !--m_nRef ) delete this; }
1107 wxSUPPRESS_GCC_PRIVATE_DTOR(RefCounted)
1111 Notice that there should be no semicolon after this macro.
1115 #define wxSUPPRESS_GCC_PRIVATE_DTOR_WARNING(name)
1118 Swaps the contents of two variables.
1120 This is similar to std::swap() but can be used even on the platforms where
1121 the standard C++ library is not available (if you don't target such
1122 platforms, please use std::swap() instead).
1124 The function relies on type T being copy constructible and assignable.
1131 wxASSERT( x == 4 && y == 3 );
1134 template <typename T
> wxSwap(T
& first
, T
& second
);
1137 This macro is the same as the standard C99 @c va_copy for the compilers
1138 which support it or its replacement for those that don't. It must be used
1139 to preserve the value of a @c va_list object if you need to use it after
1140 passing it to another function because it can be modified by the latter.
1142 As with @c va_start, each call to @c wxVaCopy must have a matching
1147 void wxVaCopy(va_list argptrDst
, va_list argptrSrc
);
