Customize right click highlight on view-based NSTableView

Question

I have a view-based NSTableView with a custom NSTableCellView and a custom NSTableRowView. I customized both of those classes because I want to change the appearance of each row. By implementing the [NSTableRowView draw...] methods I can change the background, the selection, the separator and the drag destination highlight.

My question is: how can I change the highlight that appears when the row is right clicked and a menu appears?

For example, this is the norm:

And I want to change the square highlight to a round one, like this:

I'd imagine this would be done in NSTableRowView by calling a method like drawMenuHighlightInRect: or something, but I can't find it. Also, how can the NSTableRowView class be doing this if I customized, in my subclass, all of the drawing methods, and I don't call the superclass? Is this drawn by the table itself?

EDIT:

After some more experimenting I found out that the round highlight can be achieved by setting the tableview as a source list. Nonetheless, I want to know how to customize it if possible.

Answer 1

I'd take a look at the NSTableRowView documentation. It's the class that is responsible for drawing selection and drag feedback in a view-based NSTableView.
