[Drawkit] two views, different layers?

[Graham Cox]

In your view's mouseDown: method, you can set the active layer "just  
in time" then continue with normal processing. Switching the active  
layer is usually a cheap process (as it's only changing a pointer and  
sending a couple of notifications) so you're unlikely to run into  
performance issues. And if the layer you want is already active, DK  
does nothing, so you don't even need to test for it - just set it and  
go.

cheers, Graham
