treemodelfilter = Gtk2::TreeModelFilter->new ($child_model, $root=undef)

• $child_model (Gtk2::TreeModel)
• $root (Gtk2::TreePath or undef)

treeiter = $filter->convert_child_iter_to_iter ($child_iter)

• $child_iter (Gtk2::TreeIter)

$filter->set_modify_func ($types, $func=undef, $data=undef)

• $types (scalar) type name string for one column, or an arrayref of type names for multiple columns
• $func (scalar)
• $data (scalar)

func is called as

    sub myfunc {
      my ($filter, $iter, $column_num, $data) = @_;
      ...

and should return the value from the filtered model that iter row and column number.

$filter->set_visible_column ($column)

• $column (integer)

$filter->set_visible_func ($func, $data=undef)

• $func (scalar)
• $data (scalar)
