Detailed Description

Note: Tumbler requires Qt 5.5.0 or later.

The Tumbler control is used with one or more TumblerColumn items, which define the content of each column:

  Tumbler {
      TumblerColumn {
          model: 5
      }
      TumblerColumn {
          model: [0, 1, 2, 3, 4]
      }
      TumblerColumn {
          model: ["A", "B", "C", "D", "E"]
      }
  }

You can also use a traditional model with roles:

  Rectangle {
      width: 220
      height: 350
      color: "#494d53"

      ListModel {
          id: listModel

          ListElement {
              foo: "A"
              bar: "B"
              baz: "C"
          }
          ListElement {
              foo: "A"
              bar: "B"
              baz: "C"
          }
          ListElement {
              foo: "A"
              bar: "B"
              baz: "C"
          }
      }

      Tumbler {
          anchors.centerIn: parent

          TumblerColumn {
              model: listModel
              role: "foo"
          }
          TumblerColumn {
              model: listModel
              role: "bar"
          }
          TumblerColumn {
              model: listModel
              role: "baz"
          }
      }
  }

Limitations

For technical reasons, the model count must be equal to or greater than visibleItemCount plus one. The visibleItemCount must also be an odd number.

You can create a custom appearance for a Tumbler by assigning a TumblerStyle. To style individual columns, use the delegate and highlight properties of TumblerColumn.
