Capture constructor trouble
Feb 12th, 2009, 8:59pm  
Hello there,

I'm having trouble building a simple constructor for a class to handle all my intended video methods.

The error I'm having is this: "The constructor pixel_video_OOP_rewrite.Video(pixel_video_OOP_rewrite) is undefined"

and the code...
Code:

import processing.video.*;

void setup() {
  size(640, 480, JAVA2D);
  Video video = new Video(this);
}

void draw() {
}

class Video {

  Capture v;

  void Video(PApplet p) {
    v = new Capture(p, width, height, 15);
  }

}


Any pointers as to where I'm going wrong here?

Many thanks.

Constructors have no return type, not even void.
There you declare the method Video(PApplet), not the constructor.
Note you don't even need to pass PApplet:
Code:
import processing.video.*;
 
void setup() {
  size(640, 480, JAVA2D);
  println("Setup: " + this.getClass());
  Video video = new Video(this);
}
 
void draw() {
}
 
class Video {
 
  Capture v;
 
  Video(PApplet p) {
    println("P: " + p.getClass());
    println("Video: " + this.getClass());
    println("Video's parent: " + this.getClass().getEnclosingClass());
  }
}

Aha, I just saw a simpler alternative to get the parent's instance:

<sketch name>.this

Eg. if you name your sketch VideoTest, it will be VideoTest.this.
