== '''QByteArray 概要''' ==
　Qt5.15.2

　#include <QByteArray>をインクルードする必要があります。文字列のようなバイトコードを格納するのに適したクラスです。文字列ではないバイトデータでも良いです。

　typedef型のメンバ変数はそのメンバ変数の型名を使うということを定義しています。QByteArray型の中でIterator型の戻り値などに使われます。この結びつけはSTL-style iteratorで定義されていることになっています。例えば
<syntaxhighlight2 lang="cpp">
QByteArray obj;
QByteArray::const_iterator const QByteArrayConstIterator_obj;
QByteArrayConstIterator_obj = obj.Begin();
</syntaxhighlight2>
　のような感じです。
