My hierearchical list will not changed or sorted in the NSoutlineView….that's
why I was thinking to use NSArray for the buttons.
However if I want to do it correctly, should I add an ivar like BOOL isChecked
to my OvItem class ? So I won't need an NSArray
Like this:
@interface OvItem : NSObject {
NSString *name;
NSMutableArray *children;
BOOL isGroup;
BOOL isChecked; // For NSButtonCell in the
NSOutlineView
}
Do you think this is a better idea than using NSArray ?
