The <a href="QByteArray.html"><tt>QByteArray</tt></a> is treated just as a standard random-accessed file.

You can access this buffer directly by calling <a href="QBuffer.html#buffer()"><tt>buffer</tt></a>. You can also use <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a> with an existing <a href="QByteArray.html"><tt>QByteArray</tt></a> by calling setBuffer(), or by passing your array to <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a>'s constructor.</p> <p>Call <a href="QBuffer.html#open(com.trolltech.qt.core.QIODevice.OpenMode)"><tt>open</tt></a> to open the buffer.

When you are done with accessing the buffer, call <a href="QBuffer.html#close()"><tt>close</tt></a>.</p> <p>The following code snippet shows how to write data to a <a href="QByteArray.html"><tt>QByteArray</tt></a> using <a href="QDataStream.html"><tt>QDataStream</tt></a> and <a href="QBuffer.html#QBuffer(com.trolltech.qt.core.QObject)"><tt>QBuffer</tt></a>:</p> <pre> QByteArray byteArray; QBuffer buffer(&byteArray); buffer.open(QIODevice::WriteOnly); QDataStream out(&buffer); out << QApplication::palette();</pre> <p>Effectively, we convert the application's <a href="%2E%2E/gui/QPalette.html"><tt>QPalette</tt></a> into a byte array.
