Maybe I'm just missing something obvious here, but is there an easy way to find the currently selected item in an OutlineView? Before someone gets all smart and says 'Yea, just use [outlineView selectedRow];.' Let me say that that doesn't give me the desired results. In my outline view, there are several expandable items within expandable items. So finding the currently selected item is kind of a pain. I haven't found a way to do it yet, and Apple's DragNDropOutlineView is confusing as all heck (I hate their Macro usage, makes everything confusing -- especially for newbies). Let me explain a little more. When this method fires:

- (BOOL)selectionShouldChangeInOutlineViewNSOutlin eView *)outlineView

I need to be able to find what item is selected, and then save some information based on that item.

Anyone know of a way to do this? I've been trying to figure it out for a few months now and I'm finaly at the stage of begging people to help me figure this out.

Thanks in advance,

Code:
- (id)itemAtRow:(int)row

Just pass in the selectedRow, and you're done!

OMG, you know that makes complete sense. I've been looking at itemForRow for sometime now, but it never clicked as to how it would work. It just clicked! Thanks!

Ok, I lied... I tested it out and it didn't work. *grins*

This is my code. Maybe you can see something that is making it not work?

//This method is called right before a change is made in the outlineView.
- (BOOL)selectionShouldChangeInOutlineViewNSOutlin eView *)outlineView
{
NSData *data = [textField RTFDFromRange:NSMakeRange(0, [[textField string] length])];
[[noteData objectAtIndex:[noteBoxView itemAtRow:[noteBoxView selectedRow]]] setObject:data forKey:@"Notes"];
NSLog(@"...selectionShouldChangeInOutlineView");
}

Thanks in advance,

It looks like objectAtIndex: should take an int, but you're giving it an id (from itemAtRow:).

[MaxPower2k3]

yeah, objectAtIndex needs an int, and selectedRow returns an int, so you jsut need to do...

[noteData objectAtIndex:[noteBoxView selectedRow]]

Yup, just change it to [[noteBoxView itemAtRow:[noteBoxView selectedRow]] setObject:data forKey:@"Notes"];

Thanks for the reply, but I do have one question. If I use the above code, how would my array 'noteData' know to add the desired data forKey:@"Notes"? I'm a bit confused...

I assume the object that the selected item represents listens to setObject:forKey: ?

For example, in my app I have a collection of CSSObject classes to which I can apply some values such as setName: , setSource: etc. Some of the objects can be groups etc etc. Getting the selected item, I can just call setName: after an edit for example, without having to search what item is clicked myself.


Hmm� while writing this I am confused How does your underlying model for the outline view work? A main array that contains normal objects and other arrays? Because setObject:forKey is normally a method for dictionaries, unless you make your own version for a custom class.

[DSHwrd]

Yes, it is a dictionary. Heh. I figured it'd be easier to do it that way. I think I'm kind of understanding what you're saying. Just use the datasource to add my information too. (It makes sense in my head... heh) I'll give it a shot and post back here on whether or not it works. I'm hopeful!

yay! I got it to work. Now I need to work on Drag and Drop... Yippie... Oh the joy.

Thanks for all the help,
