Hi,

Gtk::TreeSelection#selected ?

  tree_view.signal_connect('cursor-changed') do |e|
    iter = tree_view.selection.selected
  end

I’ve been trying to Gtk::TreeSelection this all weekend. I doesn’t >work.
Try it!

Could you send your test code here?
How doesn’t it work?

It doesn’t work in the sense that the ‘iter’ returned does not correspond
to any of the entries in the list structure. Sample code is attached.

Thanks. I understood your issue.
I’ll fix it.

BTW, your original questions is :

Suppose that I make a tree with the entries “Jeffrey”, “Melissa” and
“Sandy”. I want to know whether the user clicked on “Jeffrey” or whether
he clicked on “Melissa” or “Sandy”.

If you want to solve this problem now,
please try below codes:
