I've a custom view that provides a graphical representation of

the custom view, in line with Apple's human interface guidelines.
For selection with mouse clicks most things are possible, but I
cannot figure out how to easily implement shift-clicking using the
additional model so that it co-operates with the NSTableView.

I assume you're referring to the GraphicsBinding example? If so, it's
not quite what I'm after. I want to provide a contiguous selection, as
my graphical layout does lend itself to the notion of ordering. So if
you click on one object, and then shift-click on another it should make
all objects in between selected also. The graphics binding example
doesn't do this (I assume as the notion of ordering doesn't really
apply here due to the layout of the dots). It shows what I'd expect
command-click selection to do.
Any other ideas?
Thanks, Paul.
p.s. the simple scenario above isn't the problem - it's the more
complex case in the original post.
p.p.s. leaving my bind: and unbind: methods to call the superclass
implementation as in this example, combined with undo/redo, made my app
crash. Instead I only allow bind: and unbind: to pass on to super if
it's not for one of the bindings I'm implementing.
