You can! ;-)

You need to:

1. subclass NSView in the Classes tab of the NIB file window in
    IB to MyView, say
2. drag a custom view from the container views palette on some window
3. select the custom view and type Cmd-5 to change its class to MyView
4. add Python code for MyView somewhere, inheriting from AutoBaseClass,
    not NSView!
5. implement relevant methods for MyView like drawRect!

Excellent! Will be fun to extend this to mouse handling and dragging
operations...! ;-)
