Signal Management: The signal management tab is where you will designate how your input switching behaves.

Also in QML there is still the ability to connect a signal to a signal, as in Qt/C++.

Does it mean I should use signal/slots whenever possible (because they are asynchronous? ... It doesn’t mean that every normal method call should be replaced by signal/slots, that would just result in worse readability and additional overhead.

Connecting a QML signal to a regular C++ slot is easy: // QML Rectangle { signal foo(); } // C++ old-style QObject::connect(some_qml_container, SIGNAL(foo()), some_qobject, SLOT(fooSlot()); // works!
