Hi Philip,

The NSBox is itself a subclass of NSView. So, you can utilize a 
combination of removeFromSuperview and addSubview. For example, you 
could bind the box  (or create a connection in IB) to a variable in 
your main controller class ("mainBox"). Connect the "Next" button to a 
method that unloads the previous subview from that box, then adds the 
next subview ("updateSubview"). Below is some example code...

NSBox *mainBox;
NSView *currentSubview;

NSView *subView1;
NSView *subView2;
NSView *subView3;

- (IBAction) updateSubview:(id) sender
{
   [currentSubview removeFromSuperview];
   currentSubview =  subViewX             // use some logic, index, etc. to 
determine the next desired subview, and copy it to the currentSubview 
variable
   [mainBox addSubview];
}

hth,
