how to connect the signal from FinestraDelPensiero (2nd snippet), that is used in the first snippet, to qt (3rd snippet)?

Expose cpp as a "context property":http://doc.qt.nokia.com/4.7-snapshot/qtbinding.html#embedding-c-objects-into-qml-components say Engine. Now create a "Connections":http://doc.qt.nokia.com/latest/qml-connections.html element in Seconda.qml which is connected to the signal of interest and call the Engine slot.
