I seem to have solved the problem, but I'm not entirely sure why my original
code doesn't work. The NSTableView documentation says I should implement
this method:
- (BOOL)textShouldEndEditing:(NSText *)textObject
But that doesn't work, as I said. So, I looked up the NSControl
documentation, and instead implemented its equivalent method in my table
delegate:
- (BOOL)control:(NSControl *)control textShouldEndEditing:(NSText
*)fieldEditor
Which does indeed work as desired. Now all I need is to understand why the
first method doesn't work. :-) Any thoughts would be appreciated!
