Re: 4D UI code questions and observations

I would not go back and change existing code that works to do this. I might and have made use of objects rather than variable on forms when appropriate. I do not think all items on form should be objects, variables, or fields. I think it depends Regards Chuck -

It is where I’d like to go, but most of what I’ve done so far focuses on the lower level bits of the MVC pattern like binding UI objects to the model. So for relatively simple UI objects like numbers, dates, popups, etc., the modules do basically what you are talking about: set the object up and
