title: Qt regexp on QRect
body: <p>I have a QRect which I try to filter in qml using RegExpFilter
  QRect(1220,50, 500, 300)</p>
  
  <p>I want to match them like that:
  QRect([0-2000], [0-500], *, *)</p>
  
  <pre><code>SortFilterProxyModel
  {
      onCountChanged: listView.recalculate()
      id: proxyModel
      sourceModel: m_sourceModel
      filters: [
          RegExpFilter {
              enabled: true 
              roleName: "myQRectRole"
  
              pattern: ????
          }
      ]
  }
  </code></pre>
  
  <p>I am stuck as it is a QRect, is it even possible?</p>
