This class defines a signal sendToQml and a slot receiveFromQml. Both have an integer parameter. The signal is sent to QML, and the slot is invoked from QML. Signals & Slots | Qt 4.8 Signals and slots are loosely coupled: A class which emits a signal neither knows nor cares which slots receive the signal. Qt's signals and slots mechanism ensures that if you connect a signal to a slot, the slot will be called with the signal's parameters at the right time.
