    For autocompletion, there is a QCompleter class:

     QStringList list; list << "Some" << "Text" << "To" << "Complete"; QCompleter *completer = new QCompleter(list,this); ui->lineEdit->setCompleter(completer);

    Interface behavior is configured using setCompletionMode

    And, as a more complicated option, organize a drop-down list, if the entered first letters will coincide with several last names.

    This behavior corresponds to the default mode QCompleter::PopupCompletion

      Replace QLineEdit with QComboBox . The latter has a complete dictionary.

      • Then another question. In QComboBox, is it possible to enter text not from a dictionary? - yurasja
