Event/Focus/Key Listener Problem.
I am trying to write a java GUI application where one of the screen is to have several buttons. I want to make it where I can simply type in (using the keyboard) a specified key and have the focus transfer from one key to the specified key. For example, if key "A" has the focus and I want key "C" to gain the focus from key "A", I just want to press key C on the keyboard and not use the mouse. This application is written for a power user I guess.
I can make the focus traverse the button list so that's not what I want, I want the focus to pass button B if its presently on button A and I type C on the keyboard.

Write a focus manager class which maintains a list of buttons (vector) whose focus need to be
managed. This focus manager class implements the KeyListener interface. It registers itself as a valid keylistener for all the buttons in the list. Also, register this focusmanager class as key listener to the parent of all the buttons When a key event occurs on a button, the focus manager class callback gets called. In this keyPress method, send the focus to appropriate component using requestFocus method of that component (button).

I understand the solution for the most part, but I do not understand fully the part about the "parent" of the buttons. I don't exactly understand what this "parent" is. Please clarify this to me. Thanks.
