I'm not sure I understand what you're saying, but I think you may not be
I've now gotten part way to my goal by using IB to set my drawer's table
view as initial first responder. Some old posts to the list indicated that
it might be necessary to do this in my window controller's -awakeFromNib,
but doing it in IB works seems to work. My NSScrollView subclass is
recognized, and now its override of -acceptsFirstMouse: is called when I
click on the table with my app frontmost.
However, -acceptsFirstMouse: is called AFTER -tableView:shouldSelectRow: and
AFTER my -selectRow action method. I haven't thought through the
implications of that yet. Maybe all it means is that -acceptsFirstMouse:
acts as a veto authority after the selection is attempted.
But it still doesn't work when my app is in the background and I
Command-click on the table. I suspect that I also have to subclass
NSClipView and override its -acceptsFirstMouse: to return YES. I won't be
able to try that until tonight.
