Question about modeling with MVC (the pattern, not the MS stuff / non web)
- by paul
I'm working on an application in which I'm looking to employ the MVC pattern, but I've come up against a design decision point I could use some help with.
My application is going to deal with the design of state-machines. Currently the MVC model holds information about the machine's states, inputs, outputs, etc. The view is going to show a diagram for the machine, graphically allowing the user to add new states, establish transitions, and put the states in a pleasing arrangement, among other things.
I would like to store part of the diagram's state (e.g. the x and y state positions) when the machine information is stored for later retrieval, and am wondering how best to go about structuring the model(s?) for this.
It seems like this UI information is more closely related to the view than to the state-machine model, so I was thinking that a secondary model might be in order, but I am reluctant to pursue this route because of the added complexity. Adding this information to the current model doesn't seem the right way to go about it either.
This is the my first time using the MVC pattern so I'm still figuring things out. Any input would be appreciated.
