Hi, As I see now, the best way for test purposing is to have two methods one with destructor as it is now and a second one with the delete operator. In this case it will be possible at 'prg' level to test/design the final destructor for both prg class and Qt native class.

But still experimenting. It is not the case that the memory is release properly at the "END" of the application, I need to have it released as soon as an object is "destroyed". Hopefully we may find a solution with further investigations. Keep on your good work of debugging and tips. BTW which is the best case? 1 or 3 ?
