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.
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
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()).
