Trying to change spinboxdelegate example from spinbox to QTextEdit but it dosn’t show

[umen]

Hi
im trying to find out why i can’t see QTextEdit in item delegate , in my application so i remembered there is simple example in the examples
i did put simple QTextEdit in the sample code and it also didn’t show the QTextEdit why ? what im doing wrong
here is the modified code:

QWidget *SpinBoxDelegate::createEditor(QWidget *parent,
        const QStyleOptionViewItem &/* option */,
        const QModelIndex &/* index */) const
    {
        //QSpinBox *editor = new QSpinBox(parent);
        //editor->setMinimum(0);
        //editor->setMaximum(100);
     QTextEdit *editor = new QTextEdit(parent);
        //editor->setGeometry(QRect(40, 30, 401, 31));
        editor->setLayoutDirection(Qt::LeftToRight);
     editor->setLocale(QLocale(QLocale::English, QLocale::UnitedStates));
        editor->setFrameShape(QFrame::WinPanel);
     editor->setLineWidth(0);
        editor->setReadOnly(true);
        editor->setText("This is text test!!1");
        return editor;
    }
    //! [1]
 
    //! [2]
    void SpinBoxDelegate::setEditorData(QWidget *editor,
                                        const QModelIndex &index) const
    {
       /* int value = index.model()->data(index, Qt::EditRole).toInt();
     
        QSpinBox *spinBox = static_cast<QSpinBox*>(editor);
        spinBox->setValue(value);*/
     QTextEdit *textEdit = static_cast<QTextEdit*>(editor);
        textEdit->setText("This is text test!!1");
 
 
    }
    //! [2]
 
    //! [3]
    void SpinBoxDelegate::setModelData(QWidget *editor, QAbstractItemModel *model,
                                       const QModelIndex &index) const
    {
        /*QSpinBox *spinBox = static_cast<QSpinBox*>(editor);
        spinBox->interpretText();
        int value = spinBox->value();
     
        model->setData(index, value, Qt::EditRole);*/
 
     QTextEdit *textEdit = static_cast<QTextEdit*>(editor);
    }

    //! [4]

    {
        editor->setGeometry(option.rect);
    }

So what does it show when you enter edit mode?
