Nice post!

I'm not sure if the same result is applicable to most software projects. A console emulator doesn't need several types of GUI objects, while most other projects need to display and handle input for several different types of data.

In most projects I've worked on, the proportion of GUI code to business code was different: I saw apprx. 70% GUI code to 30% business code.

So a cross platform GUI layer saves a lot more development time.

Is it just me or is this a sad indictment of GUI libraries/frameworks in general? I'm not saying that the majority of situations I've seen are different, but while looking at these percentages it's actually sad that they seem likely, especially when you consider the lack of control most modern GUI solutions afford you and how you constantly have to work around their bad design. We're paying a lot for very little in the modern GUI landscape.

Is 70% of the code actually GUI code, or is it business-and-platform-logic-coupled-to-GUI code?

New kinds of widgets, composition of classic widgets, view models, event handling (selection state, drag and drop, user inputs), visuals, shortcuts and accessibility.
