How to change one object's color while useing Flatlaf

Question

1. This will change all the JRadioButton's checkmark color.

   UIManager.put( "CheckBox.icon.checkmarkColor", Color.red );
   LookAndFeel lookAndFeel = UIManager.getLookAndFeel();
   try {
       UIManager.setLookAndFeel( lookAndFeel );
   } catch (UnsupportedLookAndFeelException ex) {
       ex.printStackTrace();
   }
   updateUI();
   

2. And then I want to only change radiobutton1's color while I click another button. But it does not work.

   radiobutton1.putClientProperty( "CheckBox.icon.checkmarkColor",Color.yellow);
   

Answer 1

Use "style" can do this.

radiobutton1.putClientProperty( FlatClientProperties.STYLE,"icon.checkmarkColor:#ffff66");

This can change only radiobutton1's "icon.checkmarkColor".
