I'd like to apply the MVC pattern to a GUI we are developing for an embedded system. In this case my understanding is we would need to provide the underlying framework for listener/event actions between the Controller and View. Also, I have seen some examples where the Model send an event to the View, but perhaps that is not correct. Does that seem correct?
Does anyone know of a framework targeted to embedded devices that may have this capability?
I could suggest the Qt Toolkit. But you don't give any mention of your platform capabilities.
If your embedded device supports Java, eRCP would be the best GUI framework in that case. Check out: http://www.eclipse.org/ercp/
Model sends event to view is a way to notify the view updated about things has been changed in model. It's normal communication between M & V in MVC. However, the "view" here should be a generic view which is bound via an "observable" interface, not a concrete one.
For example:
This is a bit late, but Storyboard Suite from Crank Software is designed specifically for embedded systems and explicitly emphasizes an MVC design pattern.
Storyboard applications are based on a data deployment bundle which makes it portable to multiple operating systems, CPU architectures and rendering technologies and also provides a GUI builder that lets you use images as your 'widgets' and use Lua scripting for the system and glue logic.
I work for Crank, but you can download a free evaluation to try it out
