[Qt5-feedback] new Qt5 - great! - but: What about exceptions?

[Keith Gardner]

Sorry.  Boost exception supports the N2179-style(http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2179.html) of exception objects.  They also have a wrapper function that is used when calling throw to also include type information about the exception.  Once they make a copy of the exception, they then pass it around inside of a shared pointer.

My thoughts are that if a QThread catches an exception that was thrown in the run() method, it could emit a signal that it caught an error with the exception_ptr object as an argument.

Right, but could you point to the documentation or design information on how this is done? Or can you describe it yourself?

We can't go look at Boost's code then implement the same thing ourselves -- copyright violation. At most we could integrate with it: can you point to the docs on how to use them?

But if we could integrate with it, why can't you do the same in your application?
