 // This example shows how to create your own highlight delegate for a ListView
 // that uses a SpringAnimation to provide custom movement when the
 // highlight bar is moved between items.

 import Qt 4.7
 import "content"

 Rectangle {
     width: 200; height: 300

     // Define a delegate component.  A component will be
     // instantiated for each visible item in the list.
     Component {
         id: petDelegate
         Item {
             id: wrapper
             width: 200; height: 55

                 Text { text: 'Name: ' + name }
                 Text { text: 'Type: ' + type }
                 Text { text: 'Age: ' + age }
             }
