Extending data models with fields

elfring

Proxy models are described to some degree.
How often is a need there to extend a source data model (like a base class) with fields?

Would you like to point further information sources out for this software design approach?

Hi,

You should check KDE's KItemModels which provide some nice addition to what Qt has. From which, KExtraColumnsProxyModel which provides the base for what you are looking for.

Thanks for your hint.

Can any similar classes be integrated into the Qt software library?

SGaist

What do you mean by integrated ?

What do you mean by integrated ?

Will the collection of (proxy) data models grow anyhow?

SGaist

That I don't know.

If you have an interesting re-usable model to share then you can do a submission.
