I think you are talking about the FileDialog QML type and MessageBox. But my problem is, when I call a static method of the intermediary class which calls FileDialog's open function would not return the file URL while QFileDialog::getSaveFileName would return it. So to do it, QML would need to call another function onAccepted handler and it would need to know which function it needs to call.
I mean, for example consider a situation where a C++ class process a user input carried from QML to C++. If the user input is incorrect, I would need to ask the user some options. So I pop up a message box which presents the options to the user with this intermediary class. But when I do this, I would lose the flow of the program. So when the user responds to the message box, I would need to call another C++ function to process. But since QMessageBox's and QFileDialog's static functions create their own event loop and returns the data, I would be able to process new data without loosing the current stack and flow of the program. So QMessageBox and QFileDialog's static functions are not need to know on their event handlers, because they just returns the information that is needed so program can continue from the same stack. Like I said, I am not so exprienced with programming. I might be misjudging your advice or QML and C++ seperation.
