[Qt-interest] Qt and C++ exceptions

[Maxim Egorov]

I think you're mistaken. Yes, the implementation of exceptions in MSVC6 based on SEH mechanism, or in your terms, Win32 exceptions. It's true. But this is just a realization. Speaking about the full support of exceptions, I mean the correct processing of construction like try / catch by the compiler in accordance with the C++ standard. And the C++ compliler in MSVC6 did it. Exceptions can cross dll boundaries. You may have linked to run-time C++ library, both static and shared (msvcrt.dll). If you choose to use msvcrt.dll, you still can handle exceptions of type std:: exception, and derived from it (even if it had been throwed in another dll) by the try / catch construction. In any case, the compiler used in MSVC6 is out of date and I think there are not many developers using it.
P.S.
Sorry for my English.
