QJSEngine: Q_INVOKABLE method that returns pointer to subclass of QObject

[dimonomid]

Suppose I have some class that derives from QObject:

class MyTest : public QObject {
Q_OBJECT
   // ... 
};

class MyTest : public QObject {
Q_OBJECT
   // ... 
};

To copy to clipboard, switch view to plain text mode 

And I want to return pointer to this class from Q_INVOKABLE function, like this:

Q_INVOKABLE MyTest *createMyTest(){
      return new MyTest();
   }

Q_INVOKABLE MyTest *createMyTest(){
      return new MyTest();
   }

To copy to clipboard, switch view to plain text mode 

However, when I try to invoke this method from the script in QJSEngine, I get the following error:

Error: Unknown method return type: MyTest*

Error: Unknown method return type: MyTest*

To copy to clipboard, switch view to plain text mode 

If I make createMyTest() to return QObject* instead of MyTest*, it works. But of course this would force me to use casts, which I'd like to avoid. So, how to make it work with MyTest*?
Just by chance, I tried to declare metatype, as follows:

Q_DECLARE_METATYPE(MyTest*)

Q_DECLARE_METATYPE(MyTest*)

To copy to clipboard, switch view to plain text mode 

But this didn't help.
Thanks in advance.

This helped:

qmlRegisterType<MyTest>();

qmlRegisterType<MyTest>();

To copy to clipboard, switch view to plain text mode 

However, documentation of QJSEngine is far from perfect: it's really hard to catch (at least for me) interrelation between QML and QJSEngine. What do they have in common, and where do they differ.

In your case it might even be sufficient to use qmlRegisterUncreatableType().

Though the main question is if you really need to use the function from C++ and script?
