We do this internally, but don't usually expose it. If you're going to 
contribute it, please make sure your contribution uses QMetaCallEvent.

Anyway, the important question is whether you have the QThread for that thread 
or an object that lives in that thread. If you have the latter, it's already 
easy to do so:

  QMetaObject::invokeMethod(obj, Qt::QueuedConnection, [] { doSomething(); });
