Stopping edition of a NSTableView's row after hitting return

• Jerome Foucher Stopping edition of a NSTableView's row after hitting return Feb 04 2005, 19:00
  Hi list,
  
  I'm using a NSTableView with custom cells (subsclass of NSTextFieldCell) which can be edited.
  
  When I double-click on a cell, it's been edited normally. But when I hit enter to validate the change, the edition continues and the next cell si been edited.
  
  I would like the edition to stop. So, inside tableView:setObjectValue:forTableColumn:row:, I tried to call [tableView abortEditing], but this has no effect at all.
  
  Trying to prevent the next cell from been edited in tableView:shouldEditTableColumn:row: is not really possible, as if I return NO for row x, the method will be called for row x+1 and so on.
  
  Can someone tell me how to stop the edition ?
  Thanks
  Jérome

  Check the archives. Hint: search on NSTableView and textDidEndEditing. m.

  Subclass NSTableView and override -textDidEndEditing: to catch returns
  and end editing.  Normally, I'd refer you to the archives, since that's
  where I got much of my code.  But since it took me considerable time to
  actually get it working, I'll post it here for you and posterity.
  
  - (void)textDidEndEditing:(NSNotification *)notification
  {
  if([[[notification userInfo] valueForKey:@"NSTextMovement"] intValue]
  == NSReturnTextMovement) {
    NSMutableDictionary *newUserInfo;
    newUserInfo = [[NSMutableDictionary alloc]
                              initWithDictionary:[notification userInfo]];
    [newUserInfo setObject:[NSNumber numberWithInt:NSIllegalTextMovement]
        forKey:@"NSTextMovement"];
    notification = [NSNotification notificationWithName:[notification
  name]
                                                      object:[notification object]
                                                   userInfo:newUserInfo];
    [super textDidEndEditing:notification];
    [newUserInfo release];
    [[self window] makeFirstResponder:self];
  
    //Notification that table view has ended all editing
    [[NSNotificationCenter defaultCenter]
  postNotificationName:PFTableViewDidEndAllEditingNotification
  object:self];
    //Delegate endEditing
    id delg = [self delegate];
    SEL ds = @selector(tableViewDidEndAllEditing:);
    if([delg respondsToSelector:ds]) [delg performSelectorOnMainThread:ds
  withObject:self waitUntilDone:NO];
  }
  else {
    [super textDidEndEditing:notification];
      }
  }
  
  Note that everything from the "//Notification..." comment to the end of
  the block is my own code added for my own purposes, and is not required
  in order to do what you want.

  Thanks a million. I think it would be a good idea to post that code for
  a tutorial on some Cocoa sites like Cocoa Dev Central....
  
  As for the archives, I have to admit that I did not search the archives
  correctly, as I tried this morning looking for NSTableView + editing
  and got the answer in a few minutes.
  My bad.
