Qt: alternative to QMetaObject::invokeMethod

In Qt, I often use something like QMetaObject::invokeMethod(this, "myMethod", Q_ARG(bool, foo)) (effectively, this causes the method call + args to be queued and later executed on the correct event queue).

Is there a way to use method references instead of using the method name as string (i.e. use &MyClass::myMethod instead of "myMethod"), while still queueing execution?

Since Qt 5.10 there are two QMetaObject::invokeMethod overloads which accept functor or a pointer to a member function as an argument.

Inside the same thread you can use QTimer::singleShot overload accepting functor (since Qt 5.4) and use zero milliseconds timeout.
