Using a QTimeEdit in a delegate - WITHOUT having the values re-set to 00:00:00 when the cell is double-clicked

Hello,

I have a QT project with a QTableWidget.  When the form is loaded the QTableWidget is populated with hard-coded values.  These values are all QStrings that denote time values - ie:  "12:34:45", "02:33:15", etc.

When the user double-clicks on a cell in the table, I want the cell to convert itself to a QEditTime box, so that the user's input is limited to valid time values.

This is easy enough - I just use a delegate to create a QTimeEdit editor like so...

QWidget * TimeEditDelegate::createEditor(QWidget * pParent, const QStyleOptionViewItem& option, const QModelIndex& index)
{
     QTimeEdit * timeEdit = new QTimeEdit(pParent);
     timeEdit->setDisplayFormat("HH:mm:ss");
     return timeEdit;
}

The ONLY problem is, when the user double-clicks on one of these table cells - it erases whatever value was already in there, and replaces it with a "00:00:00" value.  I need it to retain the value after it is double-clicked.

Thanks in Advance,
Timj
