I have a somewhat spaced checkerboard of JPanel "cells" in a larger JPanel.
The 2-d array is rainbow colored while the background is white.
I want to make it so that hovering on a panel changes the border of one cell to a different color.
I can only .getComponent() though and change the cell itself, like size and background.
I saw someone else be able to do this though, so is there some method I don't know about?
