It seems that connect() is copying its lambda parameter around. That
means that if a lambda capture contains a non-copyable object, like a
unique_ptr, connect() cannot be used:
{
auto ptr = std::make_unique<int>(0);
connect(this, &MyQObject::mySignal,
[ptr = std::move(ptr)]() mutable { });
}
How do you propose we keep the connection alive after the scope ends, if we
don't copy the lambda?
As mentioned by the others, this seems to have already been brought up
some months ago. Furthermore, you're the reviewer for the changes:
