isItemExpandable and isGroupItem have nothing to do with NSCells. They're called for the items.
Cell-based table and outlineView reuse the cells for each row; this was a memory-saving technique 20 years ago, not so useful today. So before they drew a particular cell it had to be configured for the item; that's what the willDisplayCell methods are for. outlineView:viewForTableColumn:item: is where you can create custom views. ----- Original Message ----- From: "Nava Carmon" <ncar...@mac.com> To: cocoa-dev@lists.apple.com Sent: Thursday, June 21, 2012 12:27:02 AM Subject: willDisplayOutlineCell of view-based NSOutlineView is not called Hi, I want to customize the disclosure arrow appearance in my view-based NSOutlineView. I overrode the willDisplayOutlineCell delegate method, but it's not called. The willDisplayCell delegate method - is not called either. Is it known issue or I'm missing something? (The isItemExpandable delegate function and isGroupItem returns YES for the expandable cell) Thanks, Nava _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
