In Nimbus, how to paint TextField when MousOver?

In Nimbus, how to paint TextField when MousOver?

I recently studied to override the defaults of Nimbus. In the page of
Nimbus Defaults for the TextField, there is no key
"TextField[MouseOver].borderPainter" while there is
"Button[MouseOver].backgroundPainter". I desired to paint TextField when
MousOver as I can do for JButton. How can I achieve that? Thanks for your
help
