Description AtkSelection should be implemented by UI components with children which are exposed by atk_object_ref_child and atk_object_get_n_children, if the use of the parent UI component ordinarily involves selection of one or more of the objects corresponding to those AtkObject children - for example, selectable lists. Note that other types of "selection" (for instance text selection) are accomplished a other ATK interfaces - AtkSelection is limited to the selection/deselection of children.
