interface OnItemViewSelectedListener : BaseOnItemViewSelectedListener<Row!>
Interface for receiving notification when a row or item becomes selected. The concept of current selection is different than focus. A row or item can be selected without having focus; for example, when a row header view gains focus then the corresponding row view becomes selected. This interface expects row object to be sub class of
onItemSelected(itemViewHolder: Presenter.ViewHolder!, item: Any!, rowViewHolder: RowPresenter.ViewHolder!, row: T)
Called when a row or a new item becomes selected.
For a non
ListRow case, parameter item may be null. Event is fired when selection changes between rows, regardless if row view has focus or not.
ListRow case, parameter item is null if the list row is empty.
In the case of a grid, the row parameter is always null.
Row has focus: event is fired when focus changes between children of the row.
No row has focus: the event is fired with the currently selected row and last focused item in the row.
