Detailed Description

The KIdentityProxyModel class proxies its source model unmodified.

Since: 4.6

KIdentityProxyModel can be used to forward the structure of a source model exactly, with no sorting, filtering or other transformation. This is similar in concept to an identity matrix where A.I = A.

Because it does no sorting or filtering, this class is most suitable to proxy models which transform the data() of the source model. For example, a proxy model could be created to define the font used, or the background colour, or the tooltip etc. This removes the need to implement all data handling in the same class that creates the structure of the model, and can also be used to create re-usable components.

This also provides a way to change the data in the case where a source model is supplied by a third party which can not be modified.

class DateFormatProxyModel : public KIdentityProxyModel
{
  // ...
  void setDateFormatString(const QString &formatString)
  {
    m_formatString = formatString;
  }
  QVariant data(const QModelIndex &index, int role)
  {
    if (role != Qt::DisplayRole)
      return KIdentityProxyModel::data(index, role);
    const QDateTime dateTime = sourceModel()->data(SourceClass::DateRole).toDateTime();
    return dateTime.toString(m_formatString);
  }
private:
  QString m_formatString;
};
