gtk:filter-list-model-watch-items (object)

object -- a gtk:filter-list-model object
setting -- a boolean whether to monitor list items for changes

The accessor for the watch-items slot of the gtk:filter-list-model class gets or sets whether watching items is enabled. This allows implementations of the gtk:filter object that support expression watching to react to property changes. This property has no effect if the current filter does not support watching items. By default, watching items is disabled.
