Did you perhaps forget to set translatesAutoresizingMaskIntoConstraints = NO on one of the views you return it defaults to YES on newly-created views)? This constraint is used by the layout system to apply heights you specify elsewhere. I *think* it is one for non-AutoLayout views. If I'm misremembering, check for any other views that arrange their subviews, like NSStackViews.

The “NSView-Encapsulated-Layout” constraints are constraints that are added to represent views that are not laying out with auto layout but still need to be represented in the solution. Beyond that, I’m not familiar with the area that you are trying to resolve.

Sorry, in my email I wrote "outlineView:rowViewForItem:” when I meant to say "outlineView:heightOfRowByItem:”, which I have returning 20 or 24. This correctly changes the row height (it is being called), but the highlighting remains at 12 pixels regardless of value.

You need to implement -outlineView:heightOfRowByItem: to return the height you want for each row. Hope that helps. —Rob > On Aug 30, 2018, at 6:23 PM, Demitri Muna wrote: > > Hi, > > I’ve been hitting my head against a wall for more time than I’d like to admit > on what should be a simple problem - maybe someone can spot it immediately… > > I’m implementing a view-based source list style NSOutlineView (I’m trying to > mimic the Finder sidebar).

Bothersome "NSView-Encapsulated-Layout-Height" constraint?
Hi, I’ve been hitting my head against a wall for more time than I’d like to admit on what should be a simple problem - maybe someone can spot it immediately… I’m implementing a view-based source list style NSOutlineView (I’m trying to mimic the Finder sidebar). My header items are a different row height than the items underneath. I’ve implemented outlineView:rowViewForItem: (returns 24 for headers, 20 for items). The rows are spaced as expected in the column, but they are not drawn correctly. The cell is cropped to 12 pixels, as seen here: https://imgur.com/a/7KKgtZX I expect the highlighting to extend to the full height of the row. I tried to force this by adding two constraints, 2 pixels above and below the image, then got this: 2018-08-30 14:55:36.807612-0400 Nightlight[78272:15775715] [Layout] Unable to simultaneously satisfy constraints: ( "", "", "", "" ) This shows where the problem is: a height constraint on the row of 12 with the name "NSView-Encapsulated-Layout-Height”. This is the exact height I see being drawn. I have no idea where this is coming from or how to fix it though. Any help welcome - it’s annoying because this seems like such simple thing!
