I am not sure why my reason is so important, but i just want to do these: How to maintain there is only one instance of a topcomponent window of a specific class? How to close all topcomponent of a specific class?
OK, my reason is: when you open an editor, there is a property window, whatever how many editor you are opened, since there is only one active editor, so there is only one property window. If can't control only one instance of a topcomponent, how can we achieve this. I am not sure why you think it is so important to ask for my reason to solve a specific technical question. If people ask "how to solve my for-loop error", do we really need to know his reason to write his for-loop? Or I am thinking i am being discriminated. If people in here think i am disturbing, i can quit.
