drjdpowell, Thanks for the feedback. Boy do I have a lot to learn. I know how to do inheritance and dynamic dispatch but I don't know much about design patterns and frameworks.

I often have to create interfaces for power supplies. I often use the QMH for my overall architecture. I have created a QMH that controls multiple power supplies. It was designed in such a way that it takes a minute to add an additional power supply. Of course I am using Dynamic Dispatch to use multiple types of power supplies. It works quite well. I am trying to get better at LVOOP and plug-ins. I was thinking of creating an abstract class that contains a QMH for just one power supply. Of course I would create children for several types of power supplies. My plan with the single QMH for each power supply would be to use it as a plug-in or use a sub panel so that all the QMHs are on one UI. If anyone has any advice on the methodology please feel free to comment. Also I am new to LAVA so I hope I am not asking something that has already been solved.
