Here's a fun little method I wrote to explore this - it just fakes
an event that gradually tracks from the top of the table to the
bottom. As you can see, you wouldn't really expect it to draw
anything, but it does highlight each row in turn. The call to the
window's -displayIfNeeded is required to flush the drawing out
during the loop. <mLayersTable> is the ivar for the tableview (in
fact an outline view - I haven't tested this against a table view).
A few more clues/results...
The highlight is being drawn by drawRect: as usual - I was thinking
that some direct drawing was being done but that's not the case on
further investigation.
After running the test code, the table highlighting gets firmly set to
the blue outline style for ALL further selections. This suggests that -
menuForEvent is setting a highlighting style mode, making a note of
the row to highlight and then doing the drawing in -drawRect: Am I
warm, Corbin?
I still say that -menuForEvent: is the wrong place to be setting these
internal flags - the internal client of -menuForEvent: should be doing
that (-rightMouseDown: or something it calls) - plus the highlighting
"mode" should be public so that delegate methods that customise
highlighting could make use of it.
