Hi Bo, Hi everyone thanks for your reply and the thoughts you have spent on my problem. You are right, using these cascading loader elements is a fundamental structure of the program which will not be easy to change. The point is that everything is user editable. The user can decide which

Sure, you can look and see that the size() of a QByteArray returns an 'int', but that is only as of today. You should get into the habit of controlling the types written to QDataStreams. Actually, for reading and writing binary data files, I think it is wise to get into the habbit of using
