Accessing QObject property from a non QObject subclass in another thread

I have use case where I want to read properties of a QObject from a non QObject subclass (so no signals and slots) that is in another thread (non Qt thread).
I got the instance of the QObject form the class by using its object name property and using the find Child class from the root object.
Is it safe to do so? Are these methods reentrant? -

I would do so, yes. Even though I would not expect a threading problem with qFindChild as long as the object tree is not changing but one never knows.
