Re: NSSegmentedControl and Bindings

I'm trying to bind either of the two segments in my

As I understand the documentation, the individual segments do not work as independent controls, and what you want to do cannot be done in IB alone. The problem must be addressed through the NSSegmentedControl. I subclassed NSArrayController, assigned the NSSegmentedControl target to a method of the array controller subclass, and within that method distinguished separate actions for the individual cells. Thus the array controller subclass has a method click:,

-(IBAction)click:(NSSegmentedControl*)sender
{
    int cell = [sender selectedSegment];
    if (cell == 0) {
        [self add:sender];
    } else {
        [self remove:sender];
    }
}
