I have commented out because the module A just adding some other QVariants and QString to the bytearray with using QDataStream. That was my reason I was passing data as QByteArray between modules. Because I have seperated them and each modules serializes their own data. For example on the module A, I was constructing a QDataStream with the same QByteArray and insert QVariant and QString datas. > That doesn't mean anything. > Yes you are right, constructing a QDataStream with a bytearray overwrite that.

My intention was collect all modules datas on a single byte array (I do not understand myself why I forced to collect them on all in a same bytearray). While collecting modules datas on it, I was also be able to extracts same datas individually for modules. But I was not realized that I was not extracting same as I inserted.
