I have a NSCollectionview inside my macOS application and I want to control the knob proportion of the vertical NSScroller.

As I am loading more and more item into my collection view asynchronous, the proportion of the scroller is changing frequently and does not represent how many items there will be in the end. So if the user begins to scroll before all items are loaded, the knob shrinks while he's scrolling.

How can I set the knob proportion to an initial size, so I can represent how big the NSCollectionView will be in the end?

Are all items the same size and do you know the number of items from the start? – Willeke Aug 28 '18 at 12:57
The items are not the same size but they are of similar size. I know the number of items from the start. But I think it's not important if the proportion is not 100% correct. – Yakuhzi Aug 28 '18 at 18:48
Show placeholders? – Willeke Aug 28 '18 at 21:28
If I display over 5000 placeholders, it will not load smoothly. – Yakuhzi Aug 29 '18 at 22:05
