I have a custom list, and on the view (with the QStyledItemDelegate) I want display many things, including a text edit
(think about an online shopping cart where you have the items (photos and infos of them) and next to them you can change the quantity, but within a text edit, and not a spinbox).

This text edit should be able to communicate with the model. Currently I can only draw an empty textEdit, but I don’t know how to connect it properly to the editorEvent ( and createEditor, setEditorData).

void CustomDelegate::paint(QPainter *painter,
                           const QStyleOptionViewItem &opt,
                           const QModelIndex &idx) const
{
      // My other painting stuff (labels, shapes...)
    QStyleOptionFrame panelFrame;
    QLineEdit lineEdit;
    panelFrame.initFrom(&lineEdit);
    panelFrame.rect = rectLE;
    panelFrame.state |= QStyle::State_Sunken;
    QApplication::style()->drawPrimitive(QStyle::PE_PanelLineEdit, &panelFrame, painter);
}

QWidget *CustomDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
{
    auto editor = new QLineEdit(parent);
    editor->setText("test");
    return editor;
}


void CustomDelegate::setEditorData(QWidget *editor, const QModelIndex &index) const
{
    auto lineEdit = dynamic_cast<QLineEdit*>(editor);
    if(lineEdit)
    {
        lineEdit->setText("test2");
    }
}

As a the result I can only see an empty lineEdit and can’t really interact with it.

• If I would have multpiple lineEdits inside one modelIndex delegate, how could I differentiate them in the setEditorData and createEditor?

Thanks
