Support for multi-index containers?

[elfring]

Software libraries which support the management of multiple indexes within the same data structure are available.

• Databases manage primary keys (for example).
• Boost

Will the Qt class library improve the collaboration with such programming interfaces?

[VRonin]

Unlikely, as you already discovered there are already very mature implementations like the on in boost but feel free to propose it opening a ticket or you could also implement it yourself and commit it for review

Can another programming view help around data model indexes?

On very specific cases, the KDE API implemented KHash2Map<T,U> for bi-associative containers inside KDescendantsProxyModel but it's a very specific need, I wouldn't expect this to be needed by 99% of model implementations

Would you like to distinguish any more between the usage of one- and two-dimensional structures for data models?

Nope, the 2 dimensional structure is strictly more general of the 1D version so anything that goes for the first works in the second case.

You have been discussing a lot of theoretical problems relating to models across different threads. In all of them the feeling has been that you are uselessly overcomplicating things.
I feel it would be useful for you and easier for us to walk you through a concrete example of what you are trying to achieve rather than discuss endlessly on theoretical concepts.
