Be careful with List->append( &someOtherList ); If someOtherList goes out of scope, you will be pointing to a deleted list.
Since QList uses implicit sharing, the cost of removing the inner pointer isn't that much.

For example: if (!list->at(pos)->contains(id)) { // Do something. } _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest _______________________________________________ Interest mailing list Interest@qt-project.org http://lists.qt-project.org/mailman/listinfo/interest
