A QListView of 2 billion lines with where each line is a QString one to 7 characters in length would be 2G * (24 + 32) = 96 GB of memory use. QListWidget's overhead is much worse.
This isn't accurate; QListView (with the default delegate) doesn't cache data, and only fetches and shows what's visible in its viewport. So the actual consumption is pretty much constant no matter how big is the underlying model.
