| |
| \image qtquickcontrols2-itemdelegate.gif |
| |
| ItemDelegate presents a standard view item. It can be used as a delegate |
| in various views and controls, such as \l ListView and \l ComboBox. |
| |
| ItemDelegate inherits its API from AbstractButton. For instance, you can set |
| \l {AbstractButton::text}{text}, display an \l {Icons in Qt Quick Controls}{icon}, |
| and react to \l {AbstractButton::clicked}{clicks} using the AbstractButton API. |

| This property holds whether the delegate is highlighted. |

| highlight the current item in a ListView using the following code: |
| |
| \code |
| ListView { |
| id: listView |
| model: 10 |
| delegate: ItemDelegate { |
| text: modelData |
| highlighted: ListView.isCurrentItem |
| onClicked: listView.currentIndex = index |
| } |
