Is there a way of getting the classname of a QObject derived class without creating an instantiation of that class?

Question

I'm looking for something like this:

MyClass::metaObject()->className()

which doesn't work because at the point where this code is executed, there exists no instantiation of MyClass.

If this is somehow possible, is there a way of getting all names of the classes that have been derived from MyClass?

 MyClass::staticMetaObject.className()

Works!

@TomášZato Just use `myClassInstance->staticMetaObject().className()`. – rbaleksandar Jan 31 '17 at 15:14

@TomášZato Actually, you probably want to use `metaObject` rather than `staticMetaObject`, to get info about the actual type of the object and not the type of the pointer. – Luc Touraille Jun 14 '17 at 08:36

You should be able to use:

obj->metaObject()->className();

This gave me the desired result by returning the name of the actual class and not the base class (as oposed to the accepted answer) – George Oct 20 '21 at 22:40
