swing - Java JComboBox inner dotted border after select

Question

I want to remove that inner dotted border after select something from ComboBox.

I tried

UIManager.put("ComboBox.focus", new Color(0,0,0,0));

but not working. How can remove that border?

Answer 1

can you give this one a try ? I hope it helps

combobox.setBorder(new EmptyBorder(0, 0, 0, 0));

if you want to remove focus (i think dotted border you mention can be result of focus on widget) you can use getNextFocusableComponent() and requestFocusInWindow()
