missing vertical scroll bar

[Dale Miller]

When I execute the application using the code excerpts shown below,  
the vertical scroll bar never appears, whether I add enough text to  
overflow the clip view, or resize the scroll view by resizing the  
window so that the existing text no longer fits within the clip view.  
All of the scroll view mechanism except for the display of the  
vertical scroll bar works as expected, since I can scroll vertically  
with the mouse scroll wheel.The horizontal scroll bar appears and  
disappears when I resize the scroll view horizontally.
Changing the sequence of the "set..." messages, or issuing: [scview  
setAutohidesScrollers:NO] has no effect.


        scrollSize  = [NSScrollView frameSizeForContentSize:NSMakeSize(tvw,tvh)
                                                        
hasHorizontalScroller:YES
                                                        hasVerticalScroller:YES
                                                        
borderType:NSLineBorder];
        ...
        scview = [[[NSScrollView alloc] initWithFrame:
                                          
NSMakeRect(15.,15.,scrollSize.width,scrollSize.height)]
                                          retain];
        [scview setBorderType:NSLineBorder];
        [scview setAutoresizingMask:NSViewWidthSizable+NSViewHeightSizable];
        [scview setHasHorizontalScroller:YES];
        [scview setHasVerticalScroller:YES];
        [scview setAutohidesScrollers:YES];
        [[window contentView] addSubview:scview];
        ...
        textView = [[NSTextView alloc]
                initWithFrame:NSMakeRect(0.,0.,tvw,tvh)];
        textc = [textView textContainer];
        [textc setWidthTracksTextView:NO];      
        [textc setHeightTracksTextView:NO];
        [textView setHorizontallyResizable:YES];
        [textView setVerticallyResizable:YES];
        [textc setContainerSize:NSMakeSize(FLT_MAX,FLT_MAX)];
        [textView setTextContainerInset:NSMakeSize(0.,0.)];
        [textc setLineFragmentPadding:0.];
        [textView setFont:fixed];
        [scview setDocumentView:textView];

Does anyone see what I'm missing?
