Using typeid to get name of derived class

Question

I\'m creating a resource manager that takes in classes derived from the class Resource. My problem is that typeid(..).name() returns the wrong name of the class.

If you are using Qt library, you could use the metaobject to distinguish the resource instances.

class Resource : public QObject {
    Q_OBJECT

}; // abstract

class Texture : public Resource {
    Q_OBJECT
};

Resource *texture = new Texture();
Resource *resource = new Resource();

texture ->metaObject()->className(); // yields 'Texture'
resource ->metaObject()->className(); // yields 'Resource'
