/**
 * #GtkIconView provides an alternative view on a #GtkTreeModel.
 * 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.
 * 
 * Note that if the tree model is backed by an actual tree store (as
 * opposed to a flat list where the mapping to icons is obvious),
 * #GtkIconView will only display the first level of the tree and
 * ignore the tree’s branches.
 * 
 * # CSS nodes
 * 
 * |[<!-- language="plain" -->
 * iconview.view
 * ╰── [rubberband]
 * ]|
 * 
 * GtkIconView has a single CSS node with name iconview and style class .view.
 * For rubberband selection, a subnode with name rubberband is used.
