class GTK_ICON_VIEW
		-- GtkIconView provides an alternative view on a list model.
		-- It displays the model as a grid of icons with labels.
		-- Like GtkTreeView, it allows to select one or multiple items (depending
		-- on the selection mode, see gtk_icon_view_set_selection_mode()). In
		-- addition to selection with the arrow keys, GtkIconView supports
		-- rubberband selection, which is controlled by dragging the pointer.
