Hi Torsten,
> Maybe you forgot to call > enable_model_drag_source or enable_model_drag_dest? No, I was doing that [1]. > The following code, > adapting from an old thread on this list*, works for me: Thanks for this working example ! I was able to spot the difference with mine: how you create the "sorted model". I was doing: my $model_sort = MyTreeModelSort->new_with_model($model); while you created your own constructor ! After I changed the above line with: my $model_sort = MyTreeModelSort->new(model => $model); all suddenly worked as expected... (see attached for the complete code) Both lines are supposed to do the same, aren't they ? If I read Gtk3.pm correctly, "new_with_model" is calling "sort_new_with_model" in "TreeModel" ; is this still correct ? In any case, thanks a lot for your answer and your so valuable help ! Wish you a wonderful night. Gaëtan [1] See code attached to https://mail.gnome.org/archives/gtk-perl-list/2020-May/msg00007.html |
