GtkListBoxset_filter_func

void
gtk_list_box_set_filter_func (
  GtkListBox* box,
  GtkListBoxFilterFunc filter_func,
  gpointer user_data,
  GDestroyNotify destroy
)

By setting a filter function on the box one can decide dynamically which of the rows to show.

For instance, to implement a search function on a list that filters the original list to only show the matching rows.

The filter_func will be called for each row after the call, and it will continue to be called each time a row changes (via gtk_list_box_row_changed()) or when gtk_list_box_invalidate_filter() is called.

Note that using a filter function is incompatible with using a model (see gtk_list_box_bind_model()).
