+<p> The <a href="qdatastream.html">TQDataStream</a> allows you to serialize some of the TQt data types.
+The table below lists the data types that <a href="qdatastream.html">TQDataStream</a> can serialize
+and how they are represented.
+<p> It is best to always cast integers to a TQt integer type when writing,
+and to read back into the same TQt integer type when reading.
