Re: Smart way to get "etched" borders in Leopard

Ken,

We are probably driving you nuts with our stupidity, but I'm also 
still having a hard time getting this to work. For a textured window 
I the call setContentBorderThickness:forEdge: does seem to make a 
difference in the background, but as you say no black line is drawn 
in that case. But when I try 
setContentBorderThickness:forEdge:NSMinYEdge on a normal non textured 
window I don't see any change in it's appearance at all.

Thanks again for your help, I'm sure the answer is sitting right 
there, I just can't seem to get it.

Can someone walk me through how to make this work the really slow way :)

Jesse
