How to handle QTableView's behaviour

[norobro]

In paint() try:

QColor color = index.data().value<QColor>();

QColor color = index.data().value<QColor>();

To copy to clipboard, switch view to plain text mode

Great. Thanks a lot.

Now the updating works, but the name is kinda messed up, for it shows it's hex value instead of the proper noun. Still, this is quite an improvement.
Care to explain a little more what's going on in that line, because I'm barely keeping up with delegates, to be honest.

. . . I'm barely keeping up with delegates, to be honest.

Looks to me like you are handling delegates pretty well

Take a look at QVariant::value() in the docs. As long as the color name in your cell is recognized by Qt that statement will work. To see the list of Qt recognized color names use:

qDebug() << QColor::colorNames();

qDebug() << QColor::colorNames();

My Debian system lists 148 colors.

Regarding the text, use:

painter->drawText(option.rect.x() + 27, option.rect.y() + 20, index.data().toString());

painter->drawText(option.rect.x() + 27, option.rect.y() + 20, index.data().toString());
