custom NSRulerView

Hi,

I want to customize an NSRuler of a NSScrollView, and from the
documentation I found the method setRulerViewClass. So In MyDocument
I call:

- (void)windowControllerDidLoadNib:(NSWindowController *) aController
{
    [super windowControllerDidLoadNib:aController];

    NSScrollView    *scroller = [myTextView enclosingScrollView];
    MyRulerView    *ruler;

    ruler = [[MyRulerView alloc] init];
    [scroller setRulerViewClass: ruler];

    [scroller setHasVerticalRuler:YES];
    [scroller setRulersVisible:YES];

    [ruler release];
}


However, I get an error that scroller doesn't respond to
setRulerViewClass. This is from the docs:

+ (void)setRulerViewClass:(Class)aClass

Sets the default class to be used for ruler objects in NSScrollViews
to aClass. This class is normally NSRulerView, but you can use this
method to set it to a custom subclass of NSRulerView.


how do I solve this?

thanks,

- Koen.
