[Interest] parallel asynchrone action

Dear all, I made an action processed in another thread in QML, and I would like your review. When in QML, I click on a button, I send a signal to an object "TaskProcessor" (declared in QML) to start the action. Within this slot I start a future with QtConcurrent. Before I was using

[Interest] using a custom class as parameter of signal/slot, used in QML

Dear all, I understood how to use a struct / simple class as a parameter of a signal / slot, and it works well by value. However as soon as we have to declare the type for QML, it is not good anymore. It seems that it must be derived from QObject and passed by pointer. Do I understand well that
