<p>Note for database programmers: If you create a <tt>main.cpp</tt> file using <em>Qt Designer</em>, this file will <em>not</em> include the <tt>createConnections()</tt> function. We do not include this function because it needs the username and password for the database connection, and you may prefer to handle these differently from our simple example function. As a result, applications that preview correctly in <em>Qt Designer</em> will not run unless you implement your own database connections function.</p>
