programming question

[mhodkin]

I looking to design a (graphical) program in which a known path (such as anelectrical circuit) can be interrupted by the user. That is, the user canclick the mouse anywhere on a path to "cut" it so that the path is disabled. Once the path is cut, the item connected to the path reacts (such as a light bulb going out). From a high level point of view, what would be the best code / algorithm to design such an interface?

I would implement an event-driven schema (you can google 'delegate' and 'event' keywords).

Circuit (publisher): Detects user interaction (OnClick, OnMouseOver events)and, if criteria is met, raises the cut event.
Light bulb (subscriber): Subscribes the circuit's cut event and turn on thelight if is not already on.

Typical UI's do not use algorithms.

The code will depend a lot on whether it is Win Forms, WPF,
WinRT, ASP.NET web forms, ASP.NET MVC, GTK# or something else.
