MouseInputListener in Opengl mode
Apr 21st, 2008, 7:20pm  
I've been trying to add mouse input listener to objects in opengl, without success. It works fine in normal mode but for some reason doesn't in opengl.

This is the code not tracing any outputs :

Code:

import processing.opengl.*;
import javax.swing.event.*;

Cell cell;


void setup(){
 size (800, 600, OPENGL);
 cell = new Cell();
}


class Cell implements MouseInputListener {  
  
  Cell(){
    addMouseListener(this);
    addMouseMotionListener(this); 
  }  
  
  public void mouseDragged(MouseEvent e){
    println("mouseDragged");
  }
  
  public void mousePressed(MouseEvent e) {
    println("mousePressed");
  }
  
  public void mouseReleased(MouseEvent e){
    println("mousePressed");
  }
  
  public void mouseMoved(MouseEvent e){}  
  public void mouseEntered(MouseEvent e){}
  public void mouseExited(MouseEvent e) {}
  public void mouseClicked(MouseEvent e){}
}



but changing the rendering mode to :
Code:
 size (800, 600);

will make it work.

I've seen the buttons topic but i don't like so much having to rely on the main to notify sub classes about mouse events. http://processing.org/learning/topics/buttons.html

There might also be a better way of doing what i'm trying to do too.
I'd be happy to hear about it Wink

Thank you'

hi,
same results here, but i can recommend processing's registerMouseEvent, seen below. the initial code was found in this mouse event handling post.


Code:

import processing.opengl.*;
 
Cell cell; 
 
void setup(){
 size (800, 600,OPENGL);
 cell = new Cell(this);

}

void draw() {
}
 
public class Cell {  
   
  Cell(PApplet theParent){
    theParent.registerMouseEvent(this);
  }
 
  public void mouseEvent(MouseEvent event) {
  int x = event.getX();
  int y = event.getY();
  
  switch (event.getID()) {
    case MouseEvent.MOUSE_PRESSED:
	println("MOUSE_PRESSED");
	break;
    case MouseEvent.MOUSE_RELEASED:
	println("MOUSE_RELEASED");
	break;
    case MouseEvent.MOUSE_CLICKED:
	println("MOUSE_CLICKED");
	break;
    case MouseEvent.MOUSE_DRAGGED:
	println("MOUSE_DRAGGED");
	break;
    case MouseEvent.MOUSE_MOVED:
	println("MOUSE_MOVED");
	break;
    }
  }
}
