[Qt-interest] How to change text in itemview (not in model)?

[Justus Best]

Hi,

My solution for this would be not to override the paint method,just 
reimplement
QString QStyledItemDelegate::displayText ( const QVariant & value, const 
QLocale & locale ) const   [virtual]

and process QVariant::String.

Regards Justus
