Usage class from .java file - is there a full doc for that?

outslider

Ok, I have some problem with use of tab with pure .java file. I know that's possible, but I can't get it to work.

The code:

main tab:

import processing.core.Foo;
Foo bar;

void setup() {
}

void draw() {
}

tab called Foo.java:

package processing.core;
import java.io.Serializable;
import processing.core.PApplet;

public class Foo implements Serializable {
}

The error I get:

The package processing.core.Foo does not exist.

The Foo.java file is in the sketch folder, along with the main file (which is called fjlea.pde, so no conflict here).

I tried to put the Foo.java in the ./code directory, as well as in the "sketchbook"/libraries - also without success.

How to get it to work? Is there any doc that describes the procedure?

Here's a simple example:

"Sketch.pde":

---

// forum.processing.org/two/discussion/3677/
// usage-class-from-java-file-is-there-a-full-doc-for-that

void setup() {
  size(600, 400, JAVA2D);
  smooth(4);
  noLoop();
  clear();

  rectMode(Foo.MODE);

  fill(#0080FF);
  stroke(#FF0000);
  strokeWeight(3);

  new Foo(this).drawBox();
}

---

"Foo.java":

---

import processing.core.PApplet;

class Foo {
  static final int GAP = 15;
  static final int MODE = PApplet.CORNER;

  final PApplet p;

  Foo(PApplet pa) {
    p = pa;
  }

  void drawBox() {
    p.rect(GAP, GAP, p.width - GAP*2, p.height - GAP*2);
  }
}

Holy!

By reducing your good sketch to mine line by line I found, that the only problem was that I had pointless line:

package processing.core;

which caused problems ;)

Many thanks!

Yes, Processing doesn't support package declarations...
