So it should be renamed to "Verify class typecasts" or something. For this program the best would be to get rid of typecasts. It would need more designing and refactoring again. > The code uses some dirty tricks that are doomed to fail with newer > Delphi versions, and even more to port to FPC and other platforms. Did you find other dirty tricks than the typecast trick for setting mouse events, and delegated interface methods? > I think it is a bad example for testing the converter. Yes, it was way beyond testing the converter. I thought the manual conversion is easier. Then I became obsessed with it because I didn't understand what is going on.

I think the design of EssModel is OK but the authors implemented it in a too fancy way. About the editing abilities you mentioned. Ideally the only editing should be to select the classes and methods etc. you want included. Then an advanced layout algorithm takes care of the rest. Otherwise you have to relocate things in the diagram every time the class structure changes. In my experience code generation from a diagram doesn't work very well in practice. Or maybe there are people who can use it but I got my classes screwed up completely by using the Delphi UML tool. Then I was afraid of the whole tool and didn't want to touch it. There are now reverse engineering class diagram tools (but not for OP) with automatic layout calculation, like UMLGraph http://www.umlgraph.org/. It uses an external program (Graphviz) for layouting.
