public static final class MultiColumnListView.ColumnItem<T> extends Object
A wrapper around the model objects shown by the MultiColumnListView control. All list views managed by the control show instances of this type. This allows the control to add and remove the two marker / placeholder items that are used to visualize an ongoing drag and drop operation without requiring the application to provide model objects for these markers.
