Hi, You were right, when I click the cross button to close the window, all my new objects are deleted, even if my destructor is not called.
I tried to not using Qt GUI, and instead, using no GUI, but it is the same behavior. Actually, during the runtime, my application records some information (# of packet lost, # of packets send...), and I want to print out these information when I close my application. So I think I am going to find an other way to do this... Thanks you Sylvain for your help.
