Hi, I need to write an app which shows a lot of items at the same time some items update and undefined quantity new items come over the network. The list of items persistently grows.
I wrote a Model inherited of QAbstractItemModel, and the some time it works well, but after a while the app starts to slow down.
Do you know a decision how to fix it? Thanks.

I would say - fix your model or don't add more than maybe 100k items to it.

You can try to implement fetchMore() for your model, so only the data that you want to see gets loaded dynamically.
@Christian-Ehrlicher , hello. I thought that Qt doesn't use or handle items which aren't visible, and it doesn't matter how many items you insert into a view. Approximately 100k items and the app is slow
@gde23 thanks, I'll try your decision
