Hello,
I read that QMetaObject::invokeMethod shall be used to invoke methods of an object which is affined to a different thread from the calling thread. Lets suppose we have two threads a pthread and a qthread. Is it allowed to call QMetaObject::invokeMethod from pthread to invoke a method of a worker object in Qthread. Could you please help me understand this.

Correct.

Yes, it's allowed.

See http://doc.qt.io/qt-5/qmetaobject.html#invokeMethod for some example code.
