java - Swing: remove focus border from dialogues' buttons

Question

I wonder how can I remove this grey border from buttons in dialogues?

For simple JButtons I found a solution - just use button.setFocusPainted(false); But is there a simple way to perform the same for all buttons in all dialogues? I tried to look through UIManager properties, but it seems that there are no suitable parameters there.

Thanks in advance!

Answer 1

• from JButtons API you can to use JButton.setFocusable() and with JButton.setBorderPainted(false);

• from UIManager have to override key (valid for whole JVM instance)

.

UIDefaults defaults = UIManager.getLookAndFeelDefaults();
defaults.put("Button.focus", new ColorUIResource(new Color(0, 0, 0, 0)));

• I'd to suggest to change Color with transparency (4th paramater in a.m. code) to another more decent Color, otherwise you can't to see focus for any of `JButtons
