Added wxDECLARE_ANY_TYPE(CLS, DECL) and documented for what kind of situation it is intended: wxAny used across DLL and EXE boundaries.

@warning Caveat with shared libraries (DLLs): If you have a scenario where
|
||||
you use wxAny across application's shared library and application
|
||||
itself (or, with another of your shared libraries), then you must
|
||||
use wxDECLARE_ANY_TYPE() macro in your shared library code to
|
||||
correctly make sure that the wxAnyValueType implementation is
|
||||
generated correctly. Failure to do this will result in breakage
|
||||
of the wxAny type recognition with type in question. Below is an
|
||||
example how to use the macro.
|
||||
@code
|
||||
// In your shared library/DLL-only
|
||||
wxDECLARE_ANY_TYPE(MyClass, WXEXPORT)
|
||||
|
||||
// In your shared library/DLL source code
|
||||
WX_IMPLEMENT_ANY_VALUE_TYPE(wxAnyValueTypeImpl<MyClass>)
|
||||
|
||||
// In code using said shared library/DLL
|
||||
wxDECLARE_ANY_TYPE(MyClass, WXIMPORT)
