How to populate form asynchronously
-
I have succesfully built an QAbstractItemModel which populates my view asynchronously. Each cell of the view holds a SUMMARY of an ITEM (row) in my database.
I know which to edit the ITEM, and need to retrieve ALL fields from the row, and populate a larger form. My model above is of summary data only.
What is the right way to populate the form asynchronously? Do I have to make another model with ALL fields? (That feels wrong somehow).

@eyllanesc I don't have an example because I'm still at the design stage. But I'll try to rephrase.
My QAbstractItemModel works great when populating a view with many items. Now, I need to populate a single form, with the data from a single row of my database, for editting.
The QAbstractItemModel seems like overkill for this. I just need to retrieve the data and fill in the form. But this must be asynchronous because the source of the data is across the internet.
What mechanism should I use to fetch the data and populate the form when ready. The QAbstractItemModel seems too complex (though I imagine it would work). I'm not sure what else is available for this type of scenario.

It sounds like the program has already retrieved the data, converted it into a model, and used a view to select an element from the model. Why not use the same model again? The view used to select the data of interest should provide a current or selected QModelIndex. The secondary view can either be another QAbstractItemView which displays the same index, or directly use QAbstractItemModel::data().
