Changing look and feel for one INSTANCE of a component

Question

I am trying to change the look and feel of just ONE instance of a component. In particular, I want to change the color of the JScrollBar thumb on a certain JScrollPane. I want this change to not affect any other component, either before or after. How can I do this?? Any help would be much appreciated.

Hi acalvin3!
I have a solution. Use the UIManagers database. You should overwrite the default settings for the resource you want to change, the code is self explaining:
      UIManager.put( "Button.margin", commonMargin );
      UIManager.put( "Button.focusInputMap", commonInputMap );
      UIManager.put( "Button.font", buttonFont );To reset values you only have to use
      UIManager.put( "Button.margin", null );
      UIManager.put( "Button.focusInputMap", null );
      UIManager.put( "Button.font", null );Set values before you create your component and reset values immedeately after you created your component, otherwise you may affect other components too.
With following code you can find out default values for the whole UIManagers database:
      Hashtable defaultProps = UIManager.getDefaults();
      Enumeration enum = defaultProps.keys();
      while (enum.hasMoreElements()) {
         Object key = enum.nextElement();
         System.out.println( "key: '" + key + "'\t value: '" + defaultProps.get(key) + "'" );
      }You just have to look for the output for the component you want to change the look and feel.
Have fun...
