Signal/slots from Android(Java) to Qt(C++) and vice versa, how?

Question

Android

Greetings!
In general, subject!
The usual functionality has become lacking, you have to use JNI
. Is there a ready-made class for Java and Qt that could implement the signal / slots?

Answer 1

Well, what is the problem of your class-binding according to the model ? After receiving a callback from Java, you can emit a signal, and vice versa, pull the functions in the slot. In fact, without a preprocessor, automating such things seems unrealistic to me.
