[rgui-user] Re: [rgui-dev] Jumping Right In

[Tom Sawyer]

sorry to see that no one else is "jumping right in"

well, i'll carry on.

had some thoughts concerning possbile gui design pattern criteria:

1. the core-application, or model, should not require alteration in any
way in order to give it a gui interface.

2. ideally, the gui api allows for bindings on any of the model's
object's instance variables.

item #2 is a a rather thorny programming problem. as of yet the only
idea i've come up with is dynamically appending a method call to every
method of every bound model object. this special method keeps a record
of each bound object's instance variables. if any have changed since the
last call and a binding is defined for that instance variable then the
corrspoding binding action is called.

does that make sense? any better ideas? notions on the best way to
implement this?
