You may try too use the TextField delegate methods, especially:

- (BOOL)control:(NSControl 

 *)control textView:(NSTextView 

 *)textView doCommandBySelector:(SEL)command

You can detect that this is a return if the selector match 
@selector(insertNewline:), and in such case, return true to inhibit the event.

Return false in all other cases.

View-based NSTableView and ending editing with "return"

[Arved von Brasch]

Hello list,

After putting it off for too long, I’m migrating to view-based NSTableViews.  
I’ve worked through most of the conversion problems I’ve had, and am generally 
pretty happy.  There is, however, one problem I haven’t been able to solve.

I have a NSButton in the same window as my table.  The button has “return” as a 
key-equavlent.  This worked fine with a cell-based NSTableView, but with a 
view-based table, ending editing in the table with a “return” key press always 
triggers the NSButton as well.  This is obviously undesirable behaviour, but I 
can’t work out an obvious place to intercept the “return” key press and discard 
it.

My attempts thus far have been messing around with a subclass of the 
NSTableView. I’m thinking this is probably wrong, and I should be subclassing 
the NSTextField instead, but my experience with such things is minimal, and my 
Google-Fu has failed me in finding someone else with a similar problem.  So, my 
question is if anyone can give me a pointer to how to go about this.

Thanks in advance,
Arved
