    Hi guys, I'm working on an app a little different from many of the ones that are spoken in this forum, I want to complete words from a string in a data structure .

    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);
        }
}
