Revision 7e0fa2fc75a9c9ca3466d0a3fb6c9f302fc22a62 authored by Marc Mutz on 10 July 2012, 13:27:48 UTC, committed by Qt by Nokia on 26 August 2012, 12:29:49 UTC
Currently, we have a C++11 version that requires Q_COMPILER_DECLTYPE support, and can deal with final classes, and a C++98 version that doesn't require any C++11 features, but fails on final classes. What we're missing is a version that works for MSVC v8 and v9 (2005 and 2008), which sport the 'sealed' non-standard keywords but lack decltype support. So far, we tried to solve the problem by making class-level final special (Q_DECL_FINAL_CLASS), not defining that macro for these two compilers, even though we did define Q_DECL_FINAL, the method-level keyword. This new formulation, taken from http://stackoverflow.com/a/9655327/134841 supposedly supports all compilers with a minor #ifdef for MSVC which doesn't like applying sizeof() the way we do. However, testing has shown this to blow up on OSX. So we use the less intrusive approach: add this variant as a third version, only used by VC 2005 and 2008.
