Glenn,  [email to you bounced, perhaps others are interested]

   Apparently 1.0 will have a clip-View object to do what you want.
Until then, you can do what I did:

Create a sub-Class of Matrix, let's say ListView. In its newFrame
you set up what kind of cell it has, the SelectionCell is perfect for
a text string [like a file name or whatever]

Use a scrollText view from IB, and during -appDidInit:, set its' docView to 
listView. Here is a newFrame which works for me. CAPS are #defined as per
your needs.


@implementation ListView:Matrix

+ newFrame:(const NXRect *)frameRect
{   
    id proto = [SelectionCell new];
     const NXSize  size = { LIST_WIDTH,LIST_HEIGHT };
     const NXSize  Intersize = {LIST_WIDTH,-1. };
    [ListView setCellClass:SelectionCell];
    
    self = [super newFrame:frameRect];
    [scrollView setDocView:self];         /// It may not be created yet!!
    [self setFlip:YES];

    [self setCellSize:&size];
    [self setIntercell:&Intersize];
    [self setMode:NX_LISTMODE];
    [self setPrototype:proto];
    [self setTarget:[NXApp delegate];     /// or whoever handles action
    [self setAction:@selector(LIST_ACTION)];
    return self;
}

Hope this helps.
