yes. this is a major concept behind DataEngines: although different inside, 
the visualizations (e.g. a widget) uses all them the same way. :)

extragear/office/skrooge/skgdataengine .. in case anyone else goes looking :)

it looksing good... some small suggestions/issue:

* it's missing a sourceRequestEvent method; in the case of this DataEngine its 
implementation would be very simple: return updateSourceRequest(source);

* perhaps make "Accounts" and "Incomes & Expenditures" static const QString's 
in the .cpp file so that you don't have to worry about typos in the strings 
that are duplicated in sources() and updateSourceEvent(const QString &); 
common source of errors in DataEngines.
