I'd assume I would have to come up with a FolderController extending
either NSObjectController or NSController. Or extend
NSArrayController and fill the array from the folder.
Or go old-school and provide a data source. Probably easier in
this situation.
Ehm ...I am still a newbie that basically started my first real
Cocoa project about 1,5 weeks ago. So old-school "data source" does
not tell me that much yet :) Care to elaborate?
In general the problem I see is that the model could change
"underneith". A file could have been deleted/added outside the
application and not through the controller. Of course I could poll
the directory for changes ...or is there a way to register to
receive
file modification events?
New in Leopard: FSEvents. Tiger and below have fseventsd, but it's
private.
OK ...then I will go for polling - for now. Still waiting for the
new MBPs to switch to Leopard ;)
Have a look at kevent too (there is an Obj c wrapper for it: UKKQueue. http://www.zathras.de/angelweb/sourcecode.htm)
.
It's far better than polling.
