Yes I mean’t IDetailLayoutBuilder. When one sees DetailBuilder used as a variable name to in the code every where, it can get burnt into my head that that is the also the class name. When I write my own code I will use the name DetailLayoutBuilder in one form or another so as to know what class my variable refers to as I do in all the code I write when referring variables to class or structure types so it is easy to keep track of what refers to what.
Also what you you said about IDetailLayoutBuilder not being able to be created is something I suspected. I do not really understand at this stage how to set up a plugin application correctly so as to access many of the editor inbuilt features, variables etc like this. I suspect there will be many more and given I have only begun to look at editor plugin creation, there is much more to learn.
I will spend some more time and effort however in part one of my question to get the schematics of this widget to work. As I said, I can select the static mesh as I need and I can use this and continue on.
Thank you.
