Constructor.
| function | the function to call |
| result | a pointer to store the result in. Can be NULL if you are not interested in the result. You need to alloc and free it. The reason for using an external pointer is that Qt doc tells us that you loose ownership on QEvents when using QCoreApplication::postEvent. The Event will be deleted after being processed, thus we cannot ensure safe access to members after posting the event. |
| notify | specify your own condition to wait for. This is needed since the QApplication doc tells us that ownership of an event is handed over to QT and that it is not save to use the event after posting it. This means we cannot utilize an internal condition in the event as it might be deleted already when calling wait() on it. Do not specify this variable to get a fire-and-forget call. |
