Re: GtkIconView remove item

[Tadej BorovÅak <tadeboro gmail com>]

Hi.

You need to remove the data from underlying model and your icon view
will get updated automatically.

Sample code that is capable of removing multiple items at a time would
look like this:
------
GtkIconView  *icon_view;
GtkListStore *store;
GList        *elements,
             *iter;

/* Initialize icon_view here */

elements = gtk_icon_view_get_selected_items (icon_view);

/* Convert to row references for safe removal */
for (iter = elements; iter; iter = g_list_next (iter))
{
  GtkTreeRowReference *ref;
  GtkTreePath         *path = (GtkTreePath *)iter->data;

  ref = gtk_tree_row_reference_new (GTK_TREE_MODEL (store), path);
  gtk_tree_path_free (path);
  iter->data = ref;
}

/* Remove now */
for (iter = elements; iter; iter = g_list_next (iter))
{
  GtkTreeRowReference *ref = (GtkTreeRowReference *)iter->data;
  GtkTreePath         *path;
  GtkTreeIter          remove_me;

  path = gtk_tree_row_reference_get_path (ref);
  gtk_tree_model_get_iter (GTK_TREE_MODEL (store), &remove_me, path);
  gtk_tree_path_free (path);

  gtk_list_store_remove (store, &remove_me);
  gtk_tree_row_reference_free (ref);
}

g_list_free (elements);
