Creating forms with dynamic graphic ("annotation") objects

[Former Community Member]

Is there a documented method in Designer to create dynamic

graphical objects?



Practical example: I want to draw a line between coordinates calculated

based on filling some numerical fields in a form.



Directly related to this question (critic): How is that possible to say that Annot methods work in Designer static forms when it's obvious they don't and how it's possible to have a lot of new methods (like createNode) undocumented?
