how to show text and custom editor in QTableWidgetItem

[brook2lost]

my requirement is showing data using text, and editing data with custom format?
The code below display none when not editing, but show text when being clicked .

item->setData(Qt::EditRole, QVariant::fromValue<OBISCODE>(obis));
//  item->setData(Qt::DisplayRole, "1.2.3.4.5");

item->setData(Qt::EditRole, QVariant::fromValue<OBISCODE>(obis));
//  item->setData(Qt::DisplayRole, "1.2.3.4.5");

To copy to clipboard, switch view to plain text mode
