Pure Virtual Method Called Error


What kind of "thing" can own an object? Jokes about Monica's haircut Where can I find my minimum tire pressure? Sun's compiler generated the same message, but Sun's debugger provided some additional information. Figure 1. Source

A derived class must define all inherited pure virtual functions of its base classes to be concrete. The destructor in ShapeProperties is to tell Triangle to remove a specific property of ShapeProperties from it's collection of QList. A collection of objects; for example, all the smart pointers that point to the owned object. In fact, it doesn't look like it would cause the problem you're seeing.

Scott Meyers also addresses this in Item 13, "Use objects to manage resources," and Item 14, "Think carefully about copying behavior in resource-managing classes," in the third edition of Effective C++. share|improve this answer answered Mar 23 '11 at 15:22 Alexander Poluektov 4,9371521 2 Or you call method while object is destructing.
