I am an experienced java programmer but a newbie in InteliJ platform plugin programing. I want to start a development of my very own plugin. The idea is to have a little bit more sophisticated tools for real-time class creation in the Diagrams dialog. The dialog is already there so I would like to reuse it and add my own code (additional view and some creational dialogs).
I have already seen this video and cloned the idea comunity project. Please would anybody know, where to find the UML Diagrams dialog in the code (to extend it)? Or how to add a functionality to it directly by plugin? I am a bit confused with the sources and I would appreciate any help.
Thank you very much.
