Here is a good question for everyone. In a NSTableView, how do you add sub table? ie, you click on a triangle and it expands to show a few more rows? If someone could help on that it would be greatly appreciated. Oh and if you need more info, just ask!

Isn't that a different kind of control? There is an element in IB which looks like the Finder tree view with columns.

yes, it's called NSOutlineView, a subclass of NSTableView

No, it is a NSTableView that I need to use. I know it can be done somehow, I just dont know how.... yet! It would be similiar to how iTunes expands the table.

Ok, you got that while I was typing my reply. I will check on it now. Thanks!

When you access the playlist from another computer, you can expand it. Also on the free radio stations. I am guessing it is the same.

hmm, never saw that before. Anyway, it's probably not exactly the same since iTunes is Carbon and its table view has significant differences from NSTableViews. But from 10 seconds of playing with it I can't find any differences.

Yeah it will be a little different, but it should work fine. I will see tonight though...

I think you want NSOutlineView, which is a subclass of NSTableView.

djohnson · Apr 3, 2004, 02:01 PM

Yeah I figred that out already....

Angus_D · Apr 3, 2004, 02:15 PM

That's what I get for not reading the thread properly. Doh!

I'll add a pseudo-useful comment that there's some decent sample code in /Developer/Examples/AppKit (OutlineView and DragNDropOutlineView).

Just an update for those that might need to use a NSOutlineView in the future... Here is an awesome link with code, that once modified to fit your code, will work wonderfully.

So far this NSOutlineView has been the most difficult part of Cocoa/Objective-C to wrap my brain around, but well worth the effort!!!!
