Your biological and technological distinctiveness will be added to our own. Resistance is futile.
Please ask Qt related questions on the forum and not using private messages or visitor messages.

Another way to get to that kind of error (related to pointer being invalid) is by allocating child widgets on the stack and if the parent is deleted (or goes out of scope) first it calls delete with the child address (that is actually not allocated on heap so delete will cause the error).
