QCompleter doesn't work

It's not showing any popup or error. It silently doing nothing.

QStringList dictionary;
dictionary << "exampleOne" << "Two" << "blah" << "hello";
dictionary.sort();
QCompleter * completer = new QCompleter(dictionary,ui->inRawText);
completer->setModel(new QStringListModel(dictionary, completer));
completer->setCompletionMode(QCompleter::PopupCompletion);
completer->setCaseSensitivity(Qt::CaseInsensitive);
completer->setWidget(ui->inRawText);

inRawText is instance of QTextEdit class.

EDIT: Signals (activated and highlighted) are not emited.

EDIT: Popup is shown only if I call complete() slot. It's stupid, I must reimplement QTextEdit class and it's keyPressEvent handler ... damned QT...

Making a QTextEdit the parent of a QCompleter only affects the ownership hierarchy, it does not mean that the QCompleter must start processing text for the QTextEdit.

In fact, QCompleter does not function as an autocompleter for QTextEdit, it only works for QLineEdit and QComboBox and you use the setCompleter() function of those two classes to start the autocompletion.

Read the documentation of QCompleter for more information.
