Someone has any idea how to do it?

  1. I don’t know if I understand correctly:

    QStringList wordList; wordList << "alpha and beta" << "omega" << "omicron" << "zeta";  QCompleter *completer = new QCompleter(wordList, this); completer->setCaseSensitivity(Qt::CaseInsensitive);  QLineEdit *lineEdit = new QLineEdit(this); lineEdit->setCompleter(completer);

    If you type alp then you get the completion "alpha and beta" which is more than one word. There is no limit.

    Update after clarifications:

    Seems that what is requested is starting a new autocompletion after a delimiter value. In the current case this delimiter will be a space. An equivalent example would be the tree model completer from the Qt examples. This example illustrates how to solve the same situation.
