Swing: remove focus border from dialogues' but

问题:

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!

• 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

What about

JButton.setFocusPainted(false)

Here's a global fix so you don't have to do it manually for every control. From my other post: Disable JButton focus border

        // Removes the dotted border around controls which is not consistent with Windows
        UIManager.put("Button.focus", new ColorUIResource(new Color(0, 0, 0, 0)));
        UIManager.put("ToggleButton.focus", new ColorUIResource(new Color(0, 0, 0, 0)));

        // ways to remove it from other controls...
        UIManager.put("CheckBox.focus", new ColorUIResource(new Color(0, 0, 0, 0)));
        UIManager.put("TabbedPane.focus", new ColorUIResource(new Color(0, 0, 0, 0)));
        UIManager.put("RadioButton.focus", new ColorUIResource(new Color(0, 0, 0, 0)));
        UIManager.put("Slider.focus", new ColorUIResource(new Color(0, 0, 0, 0)));

        // figure out combobox
        UIManager.put("ComboBox.focus", new ColorUIResource(new Color(0, 0, 0, 0)));
