renegadex has asked for the wisdom of the Perl Monks concerning the following question:

hi perl monkies, I need help in creating a simple editable treeview. Back in Gtk2, I am using Gtk2::SimpleList. Now I am having a problem because the SimpleList was removed on the Gtk3.

Now I did my research and end up with this... 

my $model = Gtk3::ListStore->new('Glib::String');
my $list = Gtk3::TreeView->new();
$list->set_model($model);
my $cell = Gtk3::CellRendererText->new();
$cell->set('editable'=>1);
my $column = Gtk3::TreeViewColumn->new_with_attributes('name',$cell,'t
+ext',$i);
$list->append_column($column);

The problem here is that if I added a new row and tries to edit the contents of it by double clicking and typing a new text after I press enter, the new text is not updated. So I did googling around and found this site. 

http://python-gtk-3-tutorial.readthedocs.org/en/latest/cellrenderers.h
+tml#cellrenderertext

[download]

It says that I need to update the liststore manually using the edited signal. Problem is that I can't seem to find a way to properly get the iterator of the row so that I could update the liststore manually by using: 

$list->set($iter,0,'edited text here');

Please help. Thanks in Advance

    This is from Gtk2 code, but should work on Gtk3. 

    .....
....

 #this will create a treeview, specify $tree_store as its model
 my $tree_view = Gtk2::TreeView->new($tree_store);

  #create a Gtk2::TreeViewColumn to add to $tree_view
  my $tree_column = Gtk2::TreeViewColumn->new();
  $tree_column->set_title ("Select Something");

   #for editing
   my $renderer = Gtk2::CellRendererText->new;
  $renderer->set_property('editable' => TRUE);
  $renderer->signal_connect (edited => \&cell_edited, $tree_store);

.....
.....


sub cell_edited {
  my ($cell, $path_string, $new_text, $model) = @_;

  my $path = Gtk2::TreePath->new_from_string ($path_string);

        my $column = $cell->get_data ("column");
        my $iter = $model->get_iter ($path);

  $model->set_value ($iter, $column, $new_text);

}

    a problem because the SimpleList was removed on the Gtk3.

    I wouldn't say it was removed exactly, anyway its a pure-perl module -- i'm not sure if it will run under gtk3 unmodified, but modification shouldn't be hard
