Good day,
For the last few days I've been working on my own "2D Scatter Plot View" all
is going great and it looks nice:

of mouse or keyboard input except mouseDragged and mouseUp events,
just in case the user is dragging something. For this purpose I use a

Just check the OS version, because they're correlated. Leopard
supports GC-enabled apps on all four CPU architectures; Tiger and
earlier, as well as the iPhone OS, don't support GC on any

It is different, UIWindow doesn't have a method -makeFirstResponder.
When I was trying to figure this out I had assumed UIWindow had a
firstResponder outlet just like NSWindow but it doesn't. Of course
it's possible to extend the class to access the iv.
