title: QML: How to retrieve a default font object?
body: <p>I have a QML <code>Item</code> with some <code>Text</code> fields in it, which should have all the same font. Do achieve this i introduce a new property <code>myFont</code> of type <code>font</code>. Do initialize this property I use the <code>Qt.font</code> function, which creates a font object. But I have to specify at least one property (either <code>family</code> or <code>pointSize</code>). </p>
  
  <p>My Question is now: How can I retrieve the default font for the <code>myFont</code> property?
  If I create only a <code>Text{}</code> item, it has already a default font attached, how can I get the same font for the <code>myFont</code> property? (Meanwhile I use a hidden <code>Text</code> field and create an alias to it's <code>font</code> property, but I want a better solution).</p>
  
  <pre><code>Item {
   property font myFont: Qt.font({pointSize: 10})
   Text {
    id: header
    font: myFont
    text: "My Header"
   }
   Text {
    id: subject
    font: myFont
    text: "My Subject"
   }
   Text {
    id: message
    font: myFont
    text: "Some meassage!"
   }
  }
  </code></pre>
