Easier way to call NSBrowser's delegate from browser matrix?

In my implementation of browser drag-n-drop, my brower matrix class needs to send a -performSelector: to the browser's delegate when dragging begins. The view hierarchy in a browser is especially deep. Starting at the top, it goes:

NSBrowser
_NSBrowserScrollView
NSClipView
_NSBrowserColumnsContainerView
_NSBrowserColumnView
NSClipView
MyBrowserMatrix

So, for an instance of MyBrowserMatrix to call the browser's delegate, I'm using:

- (id)browserDelegate { return [(NSBrowser *)[[[[[[self superview] superview] superview] superview] superview] superview] delegate]; }

which seems somewhat ludicrous. There must be a smarter way?

Regards,
Jeremy
