I am happy to put in a feature request for the basic transformation / refactoring, since that seems to be well defined, and I can pin down a set of test cases to make sure it does what I expect it to do. That is going to need more explaining, if you are after VA doing something like that. If a signal has some overloads, you need something like:Ĭonnect(&m_senderMapper, SIGNAL(mapped(QObject *)), this, SLOT(objChanged(QObject *))) Ĭonnect(&m_senderMapper,QOverload::of(&QSignalMapper::mapped), this, &cParameterModel::objChanged) argument is expected to be a Functor or lambda without any 'this'. New syntax is only valid for 4 parameters. If there are only 3 parameters then the required type for the 3rd parameter is 'this'.īut in case of 3 parameters, you also need to add 'this' as the 3rd argument. It looks like the rule is that with 4 parameters, we can get the required type of the 2nd parameter from the 1st parameter, and the required type of the 4th parameter from the 3rd parameter. I am seeing connect() with 3 or 4 parameters.

Since I needed some examples to see what was going on here. I have hunted up a sample project built with Qt, qftp: The new format used normal c++ member function pointer syntax, where a class name is mandatory. And yes, no class name are needed or allowed there. The old format uses meta object logic (moc.exe) to resolve the function names. Zen is the art of being at one with the two'ness The main reason for asking is that if you don't need to look up the class names then this looks like it could be done quite easily with a careful regex find and replace. I am wondering how the functions were resolved if they didn't have class names in the old format.

In the old format, the functions don't have their class names, but they do in the new format.

It would be nice to automatically refactor this to modern style:Ĭonnect(sender, &Sender::editingFinished, this, &Receiver::zoomIndexChanged) There is a lot of old Qt code using something likeĬonnect(sender, SIGNAL(editingFinished()), this, SLOT(zoomIndexChanged())) Whole Tomato Software Forums - Refactor Qt signal/slot
