keyPressed() inside a class [Eclipse]

dimiro

is there any way to do this? i found this thread ( http://forum.processing.org/one/topic/using-keypressed-in-custom-keyboard-handler-class-eclipse.html) from the old forum but i did not quite understand PshiLHo`s answer. can someone make it a bit clearer? example

public class GUI{



//call keypPressed some how in here

}

and the class with setup() and draw()

public class GUIMain extends PApplet{

void setup(){
}

void draw(){

}

public static void main(String[] args) {
        PApplet.main(new String[] { GUIMain.class.getName() });

    }

}

i need to make a small gui and i think it will better to code interactivity inside this class

thanks

Based on my interpretation of post you linked to

public class GUI{

  private PApplet app;

  public GUI(PApplet app) {
    super();    // this is optional for this class
    this.app = app;
    // Any other setup code required for this class
  }

  public void keyPressed(){
    // use app.key in this method
  }

}


public class GUIMain extends PApplet{

  private GUI gui;

  public void setup(){

    gui = new GUI(this);

  }  

  public void draw(){

  }
  public void keyPressed(){
    gui.keyPressed();
  }

  public static void main(String[] args) {
    PApplet.main(new String[] { GUIMain.class.getName() });

  }

}

This is another way of doing it which gives your class greater control. The code registers your gui object to receive mouse and key events.

public class GUI{

  private PApplet app;

  public GUI(PApplet app) {
    super();    // this is optional for this class
    this.app = app;
    // Any other setup code required for this class
  }

  public void mouseEvent(MouseEvent e){
    int mx = app.mouseX;
    int my = app.mouseY;

  }

  public void keyEvent(KeyEvent e) { 
    // some useful variables that should be self explanitory
    char keyChar = e.getKey();
    int keyCode = e.getKeyCode();
    int keyID = e.getAction();
    boolean shiftDown = e.isShiftDown();
    boolean ctrlDown = e.isControlDown();

  }

}


public class GUIMain extends PApplet{

  private GUI gui;

  public void setup(){

    gui = new GUI(this);
    registerMethod("mouseEvent", gui);
    registerMethod("keyEvent", gui);
  } 

  public void draw(){

  }

  public static void main(String[] args) {
    PApplet.main(new String[] { GUIMain.class.getName() });

  }

}

thanks Quark! the second way is the one i was looking for.
