837 This macro can be used in a class declaration to disable the generation of
838 default assignment operator.
840 Some classes have a well-defined copy constructor but cannot have an
841 assignment operator, typically because they can't be modified once created.
842 In such case, this macro can be used to disable the automatic assignment
845 @see DECLARE_NO_COPY_CLASS()
847 #define DECLARE_NO_ASSIGN_CLASS(classname)
850 This macro can be used in a class declaration to disable the generation of
851 default copy ctor and assignment operator.
853 Some classes don't have a well-defined copying semantics. In this case the
854 standard C++ convention is to not allow copying them. One way of achieving
855 it is to use this macro which simply defines a private copy constructor and
858 Beware that simply not defining copy constructor and assignment operator is
859 @em not enough as the compiler would provide its own automatically-generated
860 versions of them -- hence the usefulness of this macro.
871 // widgets can't be copied
872 DECLARE_NO_COPY_CLASS(FooWidget)
876 Notice that a semicolon should not be used after this macro and that it
877 changes the access specifier to private internally so it is better to use
878 it at the end of the class declaration.
880 #define DECLARE_NO_COPY_CLASS(classname)
883 Equivalent of DECLARE_NO_COPY_CLASS() for template classes.
885 This macro can be used for template classes (with a single template
886 parameter) for the same purpose as DECLARE_NO_COPY_CLASS() is used with the
887 non-template classes.
889 @param classname The name of the template class.
890 @param arg The name of the template parameter.
892 #define DECLARE_NO_COPY_TEMPLATE_CLASS(classname, arg)
895 A function which deletes and nulls the pointer.
897 This function uses operator delete to free the pointer and also sets it to
898 @NULL. Notice that this does @em not work for arrays, use wxDELETEA() for
902 MyClass *ptr = new MyClass;
910 template <typename T
> wxDELETE(T
*& ptr
);
913 A function which deletes and nulls the pointer.
915 This function uses vector operator delete (@c delete[]) to free the array
916 pointer and also sets it to @NULL. Notice that this does @em not work for
917 non-array pointers, use wxDELETE() for them.
920 MyClass *array = new MyClass[17];
930 template <typename T
> wxDELETEA(T
*& array
);
933 This macro can be used around a function declaration to generate warnings
934 indicating that this function is deprecated (i.e. obsolete and planned to
935 be removed in the future) when it is used. Only Visual C++ 7 and higher and
936 g++ compilers currently support this functionality.
941 // old function, use wxString version instead
942 wxDEPRECATED( void wxGetSomething(char *buf, size_t len) );
945 wxString wxGetSomething();
950 #define wxDEPRECATED(function)
953 This is a special version of wxDEPRECATED() macro which only does something
954 when the deprecated function is used from the code outside wxWidgets itself
955 but doesn't generate warnings when it is used from wxWidgets.
957 It is used with the virtual functions which are called by the library
958 itself -- even if such function is deprecated the library still has to call
959 it to ensure that the existing code overriding it continues to work, but
960 the use of this macro ensures that a deprecation warning will be generated
961 if this function is used from the user code or, in case of Visual C++, even
962 when it is simply overridden.
966 #define wxDEPRECATED_BUT_USED_INTERNALLY(function)
969 This macro is similar to wxDEPRECATED() but can be used to not only declare
970 the function @a function as deprecated but to also provide its (inline)
971 implementation @a body.
973 It can be used as following:
979 // OldMethod() is deprecated, use NewMethod() instead
981 wxDEPRECATED_INLINE( void OldMethod(), NewMethod() );
987 #define wxDEPRECATED_INLINE(func, body)
990 @c wxEXPLICIT is a macro which expands to the C++ @c explicit keyword if
991 the compiler supports it or nothing otherwise. Thus, it can be used even in
992 the code which might have to be compiled with an old compiler without
993 support for this language feature but still take advantage of it when it is
1001 GNU C++ compiler gives a warning for any class whose destructor is private
1002 unless it has a friend. This warning may sometimes be useful but it doesn't
1003 make sense for reference counted class which always delete themselves
1004 (hence destructor should be private) but don't necessarily have any
1005 friends, so this macro is provided to disable the warning in such case. The
1006 @a name parameter should be the name of the class but is only used to
1007 construct a unique friend class name internally.
1009 Example of using the macro:
1015 RefCounted() { m_nRef = 1; }
1016 void IncRef() { m_nRef++ ; }
1017 void DecRef() { if ( !--m_nRef ) delete this; }
1022 wxSUPPRESS_GCC_PRIVATE_DTOR(RefCounted)
1026 Notice that there should be no semicolon after this macro.
1030 #define wxSUPPRESS_GCC_PRIVATE_DTOR_WARNING(name)
1033 Swaps the contents of two variables.
1035 This is similar to std::swap() but can be used even on the platforms where
1036 the standard C++ library is not available (if you don't target such
1037 platforms, please use std::swap() instead).
1039 The function relies on type T being copy constructible and assignable.
1046 wxASSERT( x == 4 && y == 3 );
1049 template <typename T
> wxSwap(T
& first
, T
& second
);
1052 This macro is the same as the standard C99 @c va_copy for the compilers
1053 which support it or its replacement for those that don't. It must be used
1054 to preserve the value of a @c va_list object if you need to use it after
1055 passing it to another function because it can be modified by the latter.
1057 As with @c va_start, each call to @c wxVaCopy must have a matching
1062 void wxVaCopy(va_list argptrDst
, va_list argptrSrc
);
