Re: [Development] Contribution proposal: Dispatcher class
But say, if I want to submit this as part of QtCore, doesn't that package use one consistent license which I'll have to use?

Re: [Development] Contribution proposal: Dispatcher class
So let's all upvote https://bugreports.qt-project.org/browse/QTBUG-37253. BTW, the way you've implemented the Dispatcher constructor is off. You can't give it a parent from another thread. You should use QObject::moveToThread() instead.

Re: [Development] Contribution proposal: Dispatcher class
Technically it sounds good to me. But would it be consistent with the responsibility of QMetaObject? It doesn't use any metadata from the object passed, unlike the other overloads.

Re: [Development] Contribution proposal: Dispatcher class
I don't care so much about that. I just think it'd be nice as part of the Qt core library. So I'm open for suggestions. :) However, I will say I don't want to force people to give their sources away if they use it. So a license along the lines of 'this license is here for formal purposes; but feel free to do anything you want with this,' is good enough as far as I'm concerned.
