Looking at the sample you pasted:
class TowerView < NSView
def awakeFromNib
tracking_area = NSTrackingArea.alloc.initWithRect self.bounds
self.addTrackingArea tracking_area
tracking_area.initWithRect self.bounds # <- ???
end
end
Why the extra call to -initWithRect on the instance of NSTrackingArea?
