How to remove border around bottoms?

Question

I have a JPanel with the GridLayout. In every cell of the grid I have a button. I see that every button is surrounded by a gray border. I would like to remove these borders. Does anybody know how it can be done?

Answer 1

I think it's very likely the borders are part of the buttons' GUI. You could try calling .setBorder(null) on all the buttons and see what happens!

Answer 2

Border emptyBorder = BorderFactory.createEmptyBorder();
yourButton.setBorder(emptyBorder);

For more details on borders see the BorderFactory
