GtkIconViewget_selected_items

Creates a list of paths of all selected items. Additionally, if you are planning on modifying the model after calling this function, you may want to convert the returned list into a list of GtkTreeRowReferences. To do this, you can use gtk_tree_row_reference_new().

To free the return value, use g_list_free_full:

GtkWidget *icon_view = gtk_icon_view_new ();
// Use icon_view

GList *list = gtk_icon_view_get_selected_items (GTK_ICON_VIEW (icon_view));

// use list

g_list_free_full (list, (GDestroyNotify) gtk_tree_path_free);
