52 * @short_description: A widget which displays a list of icons in a grid
54 * #GtkIconView provides an alternative view on a #GtkTreeModel.
55 * It displays the model as a grid of icons with labels. Like
56 * #GtkTreeView, it allows to select one or multiple items
57 * (depending on the selection mode, see gtk_icon_view_set_selection_mode()).
58 * In addition to selection with the arrow keys, #GtkIconView supports
59 * rubberband selection, which is controlled by dragging the pointer.
61 * Note that if the tree model is backed by an actual tree store (as
62 * opposed to a flat list where the mapping to icons is obvious),
63 * #GtkIconView will only display the first level of the tree and
64 * ignore the tree's branches.
