title: How to connect menu click with action in Qt Creator?
body: <p>I am completely new to Qt.</p>
  
  <p>I started with a new Qt4 GUI Application.</p>
  
  <p>Using the designer, I have created a menu like so:</p>
  
  <pre><code>File
   - Exit
  </code></pre>
  
  <p>How do I get an action associated with the menu item?</p>
  
  <p>I found something called the 'Signals and slots editor' but have no idea how to use it.</p>
