I followed your demo to create a memory sqlite instance, that's very cool. I always keep the db object as class member before, now I know how to access this resource from a pure name. However I face a weird phenomenon which I successfully opened sqlite on memory, but when I operate from another lamada and Qt warns me db not open. I close the app for a few seconds, it recovers, and when I run the app a few more times, it give me the same message. At present I think it's a little unstable for practical use.
