[PySide] QStandardItemModel vs QAbstractItemModel

[Frank Rueter | OHUfx]

Hi,

I am building a spreadsheet widget for custom data and will need many 
custom editors and item delegates.
The amount of items will potentially be in the 100,000s and a lot of 
filtering will be going on.

I started using the QStandardItemModel and so far things are working 
fine, but I haven't implemented the delegates or editors yet, and I will 
also have to override the data()/setData().

I'm wondering if I should switch to using the QAbstractItemModel before 
proceeding but can't make up my mind.
I am using some of the QStandardItemModel's method's, such as clear() 
and item() and setItem(), but I guess those are easy to re-implement.

The docs say that one should consider using QAbstractItemModel for 
efficiency and flexibility, but I am struggling to make an educated 
decision because I haven't used model/views often enough yet to know 
about all the pros and cons.

Any advice on how to make that decision would be much appreciated. I'd 
hate to finish writing the code only to find out that it's too slow for 
large data sets, and then re-jig everything to use the QAbstractItemModel.


Thanks,
frank
