Change colors to all components in a consistent way

Question

Is there a way to change color to all components of an application (or of a JFrame), such as all JButtons backgrounds, JFrame backgrounds etc.?
I suppose i've to deal with UIManager defaults, but is there some facility, or some check-list to help achieve this task?.
Thanks in advance

Answer 1

Check out my ComponentMapper class. You could do it with this by running the mapper on the contentpane (and potentially the JMenuBar too if you like)
You are welcome to use and modify this code but please don't change the package or take credit for it as your own work

                              System.out.println(c.getClass());
                              c = c.getParent();
                         //disable the textfield
