How to edit NSOutlineView item

Question

I have a Outlineview using a NSTreeController, for the most part everything is functioning as I would like except when a new item is added, I would like the item automatically selected for editing. In the past when using a NSTableview I would determine the row the item is located and used the function

- (void)editColumn:(NSInteger)columnIndex row:(NSInteger)rowIndex withEvent:(NSEvent *)theEvent select:(BOOL)flag

However, since NSOutlineView uses NSindexPath, I’m struggling with how to accomplish this, so is there a function available to pass a NSIndexpath as opposed to a row to achieve the same result. Or should I have a different approach for NSOutlineView.

Answer 1

Turns out my problem was related to the addChild method, the documentation for addChild indicates the following;

Special Considerations

Beginning with OS X v10.4 the result of this method is deferred until the next iteration of the runloop so that the error presentation mechanism can provide feedback as a sheet.

So, I added the following, with the corresponding selector

[self performSelector:@selector(editNewSector:) withObject:nil afterDelay:0];

Everything seems to be working now,my code is below

- (IBAction)addChildSector:(id)sender
{
    [[self myTreeController] addChild:sender];
    [self performSelector:@selector(editNewSector:) withObject:nil afterDelay:0];
}

- (IBAction)editNewSector:(id)sender
{
    NSTreeNode *nodeSector = [[self myOutlineView]
                                   itemAtRow:[[self myOutlineView] selectedRow]];

    NSInteger row = [[self myOutlineView] rowForItem:nodeSector];
    [[self myOutlineView] editColumn:0 row:row withEvent:nil select:YES];
}

You should be able to just call editColumn:row:withEvent:select: on the NSOutlineView:

[outlineView editColumn:0 row:editRowIndex withEvent:nil select:YES];

Whilst this a method from NSTableView, NSOutlineView is a subclass of NSTableView and thus you can call it on the outline view too.
