title: Navigating and addressing QMLComponents
body: <p>I am working on a desktop application the uses a QML GUI with a lot of QML Components.
  These are parts of the hierarchy:</p>
  
  <pre><code>main -&gt; toolbar -&gt; searchbar -&gt; editfield
  </code></pre>
  
  <p>and</p>
  
  <pre><code>main -&gt; resultlist -&gt; header -&gt; button1
  </code></pre>
  
  <p>I could not find a way to access the text contents of editfield in a signal handler for button1. Is it possible to do that in QML or Javascript?</p>
  
  <p>I know I can access the element in the C++ part by using the objectName property.</p>
