I have a simple class that draws a box on the screen I'm trying to figure out how to attach click event listeners to the class and I seem to be failing miserably. I want to have a text box show up in a location relative to the box when an instance of it is clicked in the applet but i cant seem to get mousePressed() or mousePressed == true to work in the class. any suggestions?

this is my code. ignore the xml part that seems to be working as i want it for now.

//a variable holding an instance of a custom class Box i called oopbox
 Box oopbox;
 
 XMLElement xml;
 XMLElement[] numOfNodes;

 void setup(){
  size(500,400);
  background(0xffffff);
  xml = new XMLElement(this, "http://images.apple.com/main/rss/hotnews/hotnews.rss");
  //print(xml);
 numOfNodes = xml.getChildren("channel/item/description");
 //print(numOfNodes[0].getContent());
   for (int i = 0; i< numOfNodes.length; i++){
      //print(numOfNodes[i].getContent() + "\n\n");
      oopbox = new Box(10, 10, int(random(width)/2), int(random(height)));
   }

 }
 
 void draw(){
   //if(mousePressed == true){
     //print("mousepressed");
   //}
 }

class Box{
  private int boxWidth;
  private int boxHeight;
  private int boxX;
  private int boxY;
  PFont font;
 
  Box(int inWidth, int inHeight, int inX, int inY){
    boxWidth = inWidth;
    boxHeight = inHeight;
    boxX = inX;
    boxY = inY;
    font = loadFont("TrajanPro-Regular-18.vlw");
   
    rect(boxX, boxY, boxWidth, boxHeight);
  }
 
  void draw(){
  if (mousePressed == true){
     print("mousepressed");/// not really flying or giving errors here   
  }
 
  }
}
