First off, thanks for bringing in the lower-tech solution. I do consider inspector plugins a last resort, and I hadn’t considered this for my use-case.
With that in mind, I’m trying to piece together how to do what I’d like to do now. My Money class is a little more complex, and I’ve already written a custom inspector plugin for that (which you helped me with in another thread). That comes with a custom SpinBox, and works well enough if I create a resource on its own.
So your example above will get me a standard range display for that passthrough, but is it possible to combine these two things? In other words, can I use _get_property_list() to display my custom MoneySpinBox (that extends SpinBox)?
