How to retrieve GTK::entry value

[Abhishek]

I have a Gtk::ListStore filled with row data.

I want the user to be able to type the row data they want to select so I am using aGtk::Entry

I have found a code sample to implement this here

  // Configure the Completion
  m_refEntryCompletion = Gtk::EntryCompletion::create();
  m_refCompletionModel = Gtk::ListStore::create(m_completionRecord);

  m_refEntryCompletion->set_model(m_refCompletionModel);
  m_entry.set_completion(m_refEntryCompletion);
  cout<<m_entry.get_completion(m_refEntryCompletion);
  m_refEntryCompletion->set_text_column (m_completionRecord.col_text);
  m_refEntryCompletion->set_minimum_key_length(1);
  m_refEntryCompletion->set_popup_completion(true);

  this->populateCompletion();

I want to extract the check that the user has entered into the Gtk::Entry field

Example here Solvakia is one of the country in the list.
When user has completed selection.

1. How do I come to know when the user has completed selection?
2. How do I extract the Completed Entry so that I highlight in the list?

Maybe I don’t understand it fully, but why not use Gtk.SearchEntry?

If “the user has completed selection” means “the user has pressed Enter”,
you can use Gtk::Entry::signal_activate(). If you use gtkmm4, that signal is
available only since gtkmm 4.7.1. If you use gtkmm 4.0.0-4.7.0, I have no good answer.

You can then get the selected text, but I don’t know an easy way to find that
text in the Gtk::ListStore.
