Conventions used

There are a number of text conventions used throughout this book.

CodeInText: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: "This API is centered on QNetworkAccessManager,which handles the complete communication between your game and the Internet."

A block of code is set as follows:

QNetworkRequest request;
request.setUrl(QUrl("http://localhost/version.txt"));
request.setHeader(QNetworkRequest::UserAgentHeader, "MyGame");
m_manager->get(request);

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

void FileDownload::downloadFinished(QNetworkReply *reply) {
    const QByteArray content = reply->readAll();
    _edit->setPlainText(content);
    reply->deleteLater();
}

Bold: Indicates a new term, an important word, or words that you see onscreen. For example, words in menus or dialog boxes appear in the text like this. Here is an example: "On the Select Destination Location screen, click on Next to accept the default destination."
