title: where does QT go to look for fonts?
body: <p>I'm using QT-4 embedded-linux. </p>
  
  <p>I have the following code in my QT application:</p>
  
  <pre><code>QFont newFont("wenquanyi", 8, QFont::Bold, true);
  
  QApplication::setFont(newFont);
  </code></pre>
  
  <p>But the character cannot be displayed correctly. I do have a <code>wenquanyi_150_50.qpf</code> file under <code>QT-directory/lib/fonts</code> in my target linux device. </p>
  
  <p>If I changed the code like this:</p>
  
  <pre><code> QFont newFont("unifont", 8, QFont::Bold, true);
  </code></pre>
  
  <p>I can see the character being displayed correctly. </p>
  
  <p>So i'm thinking that the problem is the about the path in which QT looks for a specific fonts.</p>
