Question

When an NSTableView has the style NSTableViewSelectionHighlightStyleRegular, the group rows have a very nice background and design overall.
I’d like a NSTableViewSelectionHighlightStyleSourceList Table view, but with the same header style.

Has anyone an idea how to do this, without having to subclass it?

Answer 1

I guess there is no other way then subclassing it, but it’s pretty easy:
Just make a subclass of NSTableRowView, override the DrawRect method.
Check the property self.isGroupRowStyle. If it is, then write the code to draw it.
Else just call [super drawRect:dirtyRect];

In the TableView Delegate, return an instance in the
tableView:rowViewForRow: Method.

thanks anyway
