- * QObject Reference Counts Terminology
- * ------------------------------------
- *
- * - Returning references: A function that returns an object may
- * return it as either a weak or a strong reference. If the reference
- * is strong, you are responsible for calling QDECREF() on the reference
- * when you are done.
- *
- * If the reference is weak, the owner of the reference may free it at
- * any time in the future. Before storing the reference anywhere, you
- * should call QINCREF() to make the reference strong.
- *
- * - Transferring ownership: when you transfer ownership of a reference
- * by calling a function, you are no longer responsible for calling
- * QDECREF() when the reference is no longer needed. In other words,
- * when the function returns you must behave as if the reference to the
- * passed object was weak.
