| 20 | |
| 21 | \image qtquickcontrols-itemdelegate.gif |
| 22 | |
| 23 | ItemDelegate presents a standard view item. It can be used as a delegate |
| 24 | in various views and controls, such as \l ListView and \l ComboBox. |
| 25 | |
| 26 | ItemDelegate inherits its API from AbstractButton. For instance, you can set |
| 27 | \l {AbstractButton::text}{text}, display an \l {Icons in Qt Quick Controls}{icon}, |
| 28 | and react to \l {AbstractButton::clicked}{clicks} using the AbstractButton API. |

| 52 | A delegate can be highlighted in order to draw the user's attention towards |
| 53 | it. It has no effect on keyboard interaction. For example, you can |
| 54 | highlight the current item in a ListView using the following code: |
| 55 | |
| 56 | \code |
| 57 | ListView { |
| 58 | id: listView |
| 59 | model: 10 |
| 60 | delegate: ItemDelegate { |

| 64 | required property int index |
| 65 | |
| 66 | onClicked: listView.currentIndex = index |
| 67 | } |
| 68 | } |
