Repost：The goal of my topic is to write a usable form designer, what's the use? For example, after your program is released, users feel that the position of a certain control needs to be adjusted, and the font color of a certain control needs to be modified. It doesn't matter, the user just needs to modify it. A more complicated application is that the user wants to add a field to a certain document. It doesn't matter, the user or the implementer adds it by themselves, don't change the code, don't recompile. Even if the user wants to add some processing, the implementation staff can write the code in the designer on the spot, and the system can compile it and call it at runtime.
