Re: copyWithZone error

Hi Nick, When you return your item to the table column, I believe this is setting the cell's object value to this item. The object value of an NSCell needs to conform to the NSCopyingProtocol. If you implement the method: - (id)copyWithZone:(NSZone *)zone in HDIR to return a copy of the o

Hi everyone, I have a window with a custom content view. The content view loads in a PDF image to be used as the window's background. I'd like the image to scale smoothly when the window is resized, so I set the source image to scale when resized (scalesWhenResized returns YES), and in my

I did try that at first, but the image becomes pixelated when you make the window larger. What I'm trying now is to do an initial scale of the image to some large dimensions, and then doing what you suggested. Maybe it will look fine if the only scaling it has to do is in the downwards dire
