title: Avoid newline in qDebug()
body: <p>Sometimes I want to output a single line in <code>qDebug()</code>, but with some conditional text, like</p>
  
  <pre><code>if (fontMetricsLeading &lt; 0)
      qDebug() &lt;&lt; "!!!";
  qDebug() &lt;&lt; fontMetricsLeading;
  </code></pre>
  
  <p>However, that would output them on 2 separate lines. </p>
  
  <p>Is there a way to avoid appending a new line after each <code>qDebug()</code>?</p>
