I am trying to update the color of a circle when the user move sliders using java awt standalone (homework).I have to use a Frame. I can see that my values update form the slider but I can get those values to the inner class circle in the paint method to be repainted and update the color of the circle(the objective) thanks for any help!! this is my code so far:
package cs111b;
import java.awt.*;
import java.awt.event.*;
public class ColorFactory extends Frame implements ActionListener, AdjustmentListener

Dimension Cr = new Dimension((int)(t.width*.70),(int)(t.height*.60));
int w = 300;
int x = (Cr.width/2)-(w/2);
int y = (Cr.height/2)-(w/2);

//Color c;// = new Color(rgb[0],rgb[1],rgb[2]);

}
