Changed date is not shown in QStandardItemModel

Hi,
I created an date editor in QDelegate CreateEditor like this:

            QDateEdit *deditor = new QDateEdit(parent);
            deditor->setDisplayFormat ("MM/dd/yyyy");
            deditor->setCalendarPopup (true);
            deditor->setStyleSheet ("background-color:rgb(255,217,229)");
            connect(deditor,&QDateEdit::editingFinished ,this,&myDelegate::commitAndCloseEditor );

In setEditorData I have

    QDateEdit *dateEditor = qobject_cast<QDateEdit*>(editor);
    if(dateEditor)
        {
            dateEditor->setDate (index.model ()->data (index, Qt::EditRole).toDate ());
            QVariant d(index.data (Qt::DisplayRole));
            QDate fixdate;
            fixdate = d.toDate ();
            qDebug() << "fixdate: ";
            return;
        }

In setModelData:

            QDateEdit *dateEdit = qobject_cast<QDateEdit*>(editor);
            QModelIndex updateIndex(index.model ()->index(index.row (),0,index.parent ()));

            QString fixID;
            QVariant v(updateIndex.data (Qt::DisplayRole));
            fixID = v.toString ();
            qDebug() << "FixID: " << fixID;

            model->setData (index,dateEdit->date ().toString ("MM/dd/YYYY"));

I get the following message in output:
FixID: "3"
fixdate:
When I change the date in the editor it changes the month and the day but writes YYYY as a year. What did I miss?
Thank you.

Hi
Is it correct that in setEditorData , you use
setDate (index.model ()->data (index, Qt::EditRole) <<< Edit role
but for data, you use
d(index.data (Qt::DisplayRole)); << Display role
?

Just a thought.

Hi @mrjj
I changed it to

     dateEditor->setDate (index.model ()->data (index, Qt::EditRole).toDate ());
            QVariant d(index.data (Qt::EditRole));

but the same thing happens.

@mrjj
Even the QVariant is missing the year:

QVariant:  QVariant(QString, "01/01/YYYY")

mrjj

You mean its truncated and only the last / is there but no "YYYY" or
what is missing?
If you use pure string ( not as date) does it work then?
Im not sure if save/load data that is wrong og some convert to/from string with datatime.

Hi,

Your format is wrong: it's yyyy in lower case.

You should actually store the date as a QDate rather than a string and let displayText() in the delegate to take care to display it in the correct format

I will change it from text to date. Thank you.
