Accessing inner classes

Question

I am making a simple drawing program where the user can draw with the mouse on a jpanel.
i have my program structure with one big class and two inner classes
the first inner class creates the panel you can draw on and the mouselistener events to allow a user to draw.
the second class creates another jpanel that allows you to make a color with the three properties red,green and blue. it also has two buttons. one to set the forground(the color you will draw with) and the other to set the background.
I can get the forground one to work because i set the color created to a varible and sense there are mouse listners everytime the mouse listener executes it can grab that varible and set the color of the line be drawn.
my problem is with the background, i can't figure out how to access my first inner class from my second inner class to change the panels background to corspond with the user.
is there some listener i can apply or a way to change the properties of one inner classes objects from another inner class???
please help

I dont knoew if I understand your problem exactly- but if you are wanting to access the first inner class from the second inner class- you can go through the outer class like so:
public class InnerOuter {
  public InnerOuter() {
  public void test(String s) {
    Inner i = new Inner();
    i.setBackground(s);
  class Inner{
    public String B="inner";
    public void setBackground(String s){
      //do something
  class Inner2{
    public String C="inner2";
    public void setBack2(){
      InnerOuter.this.test("red");
  public static void main(String[] args) {
    InnerOuter innerOuter1 = new InnerOuter();
