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: ( "<NSLayoutConstraint:0x60c00009be90 NSImageView:0x60c000170e00.height == 16 (active)>", "<NSLayoutConstraint:0x60c000087ee0 V:|-(2)-[NSImageView:0x60c000170e00] (active, names: DE_DataCell:0x60c000188470, '|':DE_DataCell:0x60c000188470 )>", "<NSLayoutConstraint:0x60c000082300 V:[NSImageView:0x60c000170e00]-(2)-| (active, names: DE_DataCell:0x60c000188470, '|':DE_DataCell:0x60c000188470 )>", "<NSLayoutConstraint:0x60c00009c5c0 'NSView-Encapsulated-Layout-Height' DE_DataCell.height == 12 (active, names: DE_DataCell:0x60c000188470 )>" ) 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!
