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