Dear All,
I have a problem in the following code.....I was unit testing the code
from main(). I have the FaMain base class for creating the window with
certain features. So I need all my child windows to inherit FaMain
class. Similarly, I need FaButton as base class instead of JButton.
But even after creating two buttons but1 & but2 only the second button
but2 is getting appeared......Please help me.......
