Re: Field name from "this"

I am trying to find a way to get a field's name (variable name) given a
pointer to "this".

I am trying to log all user actions in an application. In every case
where a JButton appears in my app, I use a subclass:

JButton aButton = new MyButton();

I can modify the constructor for MyButton to automatically log when the
button is clicked by adding an ActionListener. I would like to print
the class of the containing window (JDialog or JFrame) and the variable
name of the button. This way I can recreate what the user clicked.

I realize that I could use getClass().getFields() and loop thought the
Field[] until I find "this" then use Field.getName(), but I was hoping
for a faster way (less impact on performance).
