\brief A ListView with special features tailored for a look and feel fitting the
Ubuntu Touch platform.
The UbuntuListView works just like a regular ListView, but it adds special features
such as expanding/collapsing items (when used together with the Expandable item).
It provides features like automatically positioning the expanding item when it
expands and collapsing it again when the user taps outside of it.
Examples:
\qml
import Ubuntu.Components 1.2
import Ubuntu.Components.ListItems 1.0 as ListItem
Item {
ListModel {
id: listModel
}
UbuntuListView {
id: ubuntuListView
anchors { left: parent.left; right: parent.right }
height: units.gu(24)
model: listModel
delegate: ListItem.Expandable {
id: expandingItem
expandedHeight: units.gu(30)
onClicked: {
ubuntuListView.expandedIndex = index;
}
}
}
}
\endqml
