The problem I encountered is:
I have an Action which for the class under the carret finds all its inheritors and opens files with their declarations. Instead, I would like it to show a list of the classes it found and go to the corresponding file after clicking on an entry. What is the best way to do this? I tried creating a JBTable but I don't know how to show it at the right place (actually I wasn't able to make it visible at all). Any ideas from more experienced developers?
