      error C2065: 'data structure' : undeclared identifier

      please define what you mean. maybe provide an example?

        what I mean is that the QCompleter read a QString and not a QTextEdit or QLineEdit

          Can you provide an example of what you want to achieve?
          something like: "I type a string in a QLineEdit and I want QCompleter to complete using a list of strings I have in a database"

            That is not what I want to do. I'm writing a QTextEdit, but in a QString am keeping what am writing, without showing what is in the QTextEdit, then, I want to complete what is in the QString with a database in a file

              with a database in a file

              If you mean a SQLite DB then just use a QSqlTableModel as QSqlQueryModel with setModel()

              want to complete what is in the QString

              call setCompletionPrefix() with the string you want to complete and just iterate through the completions

                It is not a database, it is a file with a long list of words

                If you mean a SQLite DB then just use a QSqlTableModel as QSqlQueryModel with setModel()

                Thanks

                  Then read all the words in a QStringList and use a QStringListModel with setModel()

                    I know how to do that part. Thanks again.

                    By using the setCompletionPrefix() funtion the QCompleter does not work. Can you show me how you do it

                        Let's see, I use what you tell me about setCompletionPrefix (), but on any side it raises the popup.
                        What I do is that I connect a signal that passes the prefix and a slot that look like this:

                        void MineTextEdit::completeWord(QString cad)
{
    if(cad.size() > 3)
        {
            this->setFocus();
            c->setCompletionPrefix(cad);
            QRect cr = cursorRect();
            cr.setWidth(c->popup()->sizeHintForColumn(0)
                        + c->popup()->verticalScrollBar()->sizeHint().width());
            c->complete(cr);
        }
}
