Struggling with TreeModelFilter

[Mike Martin <mike redtux org uk>]

Hi

I have a small (3 columns including filter column) treeview with a treemodel filter.

Editing works fine if no filter is applied, but if a filter is applied I cant get the edit to apply to the correct row in the underlying model.

I assume its something to do with setting an iter_to_child_iter mapping , but where?

Code

###setup  model###

my $tag_model=Gtk3::ListStore->new('Glib::String','Glib::String','Glib::Boolean')
my $filter=Gtk3::TreeModelFilter->new($widget_table{tag_model});
$filter->set_visible_column(2);

my $tag_view=Gtk3::TreeView->new();

$tag_view->set_model($filter);

the editing setup code is

my @tvctrl=(
[0,'text','tag',0],
[1,'text','value',1],
[2,'bool','vis',1]
);

&tv_cols(\@tvctrl,$tag_view,$tag_model);
  
sub tv_cols {
 my ($cols,$list,$liststore)=@_;

foreach my $col (@{$cols}){
my $column;   
my $r;
my $id=$col->[0];
if ($col->[1] eq 'text'){
$r=Gtk3::CellRendererText->new;
$r->set( editable => $col->[3] );

$column = Gtk3::TreeViewColumn->new_with_attributes(
                $col->[2],
                $r,
                   'text' => $col->[0]
                );
                my $model1=[$liststore,$id];
$r->signal_connect (edited => \&cell_edited, $model1);
}
$list->append_column($column);
}

sub cell_edited {
  my ($cell, $path_string, $new_text, $model1) = @_;
my ($model,$column)=@{$model1};
  my $path = Gtk3::TreePath->new_from_string ($path_string);
        my $iter = $model->get_iter ($path);
my $gvalue = Glib::Object::Introspection::GValueWrapper->new (
    'Glib::String', $new_text);
  #$self->{stack}->child_set_property ($child, 'needs-attention', $gvalue);
  $model->set_value ($iter, $column, $gvalue);

}
