    Hi,
    I have a problem with displaying time in the QTableView.
    I want to display time in "mm:ss" format so I defined createEditor method in my delegate like that

    QWidget *MyDelegate::createEditor(QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index) const
    {
        QTimeEdit *timeEdit = new QTimeEdit(parent);
        timeEdit->setDisplayFormat("mm:ss");
        timeEdit->setAlignment(Qt::AlignCenter);
        return timeEdit;
    }
    

    When I set a cell value say QTime(0,0,10) I see "00:00" in that cell,
    after doubleclick "00:10" and when I defocused this cell I can see 00:00 again.
    I checked data saving to model and they had proper value "00:00".

    Any suggestion?
    Thanks in advance

      Hi. I have to say I am confused by your description. Maybe somebody else will understand better.

      Can we start with one thing: are you aware that createEditor() is only called while a cell is being edited (e.g. double-click)? The rest of the time is just a non-widget delegate displaying the text of a time.

      The display of values, whether for edit or not, does not affect what value is in the model. setEditorData() and setModelData() transfer values between model and editor.

      I do not know what issue you are reporting where.

          Hi,

          Implement the displayText method of your delegate to return what you want to show.
