    \brief Basic item delegate that can be used in various views and controls.

    \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 2}{icon},
    and react to \l {AbstractButton::clicked}{clicks} using the AbstractButton API.

    \qmlproperty bool QtQuick.Controls::ItemDelegate::highlighted

    This property holds whether the delegate is highlighted.

    A delegate can be highlighted in order to draw the user's attention towards
    it. It has no effect on keyboard interaction. For example, you can
    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
        }
    }
    \endcode

    The default value is \c false.
