/**
 * A `SelectorWithWidgetPreference` with additional features:
 * - Propagates the supplied `app:extraWidgetIcon` drawable to the extraWidget
 * - Propagates the supplied `app:extraWidgetId` id to the extraWidget (the icon on the right)
 * - Propagates the supplied `app:checkboxId` id to the checkbox (or radio button, on the left)
 * - Allows defining a "disabled click listener" handler that handles clicks when disabled
