[odb-users] Qt and classes derived from QObject

[Diego Fernando]

Hi Boris,

Employee and Person class

class Person : public QObject

class Employee : public OQbject
{
  Person *person;
}

It's compile output:
error: invalid cast from type 'odb::object_traits<Person>::pointer_type
{aka QSharedPointer<Person>}' to type
'odb::pointer_traits<Person*>::pointer_type {aka Person*}'
             obj_traits::object_type > (id));

Show this line on code

        // If a compiler error points to the line below, then

        // it most likely means that a pointer used in a member

        // cannot be initialized from an object pointer.

        //

        v = ptr_traits::pointer_type (

          static_cast<pgsql::database*> (db)->load<

            obj_traits::object_type > (id));

      }


I am using Qt and QML and exists some way to make this works without
duplicate the code where one class is derived from QObject and another no.


Thank you
