Is there an easy way to change the behavior of a Java/Swing control when it gets focus?

When I've needed this in the past, I've created subclasses of the components I wanted to add "auto-clearing" functionality too. Eg.

A separate class that attaches a FocusListener to the desired text field can be written. All the focus listener would do is call selectAll() on the text widget when it gains the focus.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
