public static final int in javafx

[Fabricio Sanchez]

Hi there,

I can't find a way in javafx to use public static final int variables.
Can anyone tell me the official way to do this (or a work around)?

Example in java:

public class Animal {
    public static final int COW = 0;
    public static final int BIRD = 1;
    public static final int FISH = 2;

    int type = COW;

    public setType( int type ) {
        this.type = type;
    }

    public static void main (String[] args) {
        Animal a = new Animal();
        a.setType(Animal.BIRD);
    }
}

javaFx attempted code:

public class Animal extends CustomNode {

    public def COW:Integer = 0;
    public def BIRD:Integer = 1;
    public def FISH:Integer = 2;
    public var type:Integer = COW on replace {
        println( "animal = {type}");
    };
}

// On my Main.fx
var a:Animal;

Stage {
    title: "Application title"
    scene: scene = Scene {
        width: 640
        height: 480
        fill: javafx.scene.paint.Color.BLACK
        content: [
            a = Animal {
                type: a.BIRD 
            }
        ]
    }
}

However the above doesn't work. I'm guessing because maybe I'm trying to access a value before the object has been initialised.

Any help greatly appreciated.

Best regards,

Fabricio

I think I found my own solution.
Declare the variables outside the public class .. { .. }
So, in my case:

  
// Animal.fx
package blah.blah;

import javafx.scene.CustomNode;

public def COW:Integer = 0;
public def BIRD:Integer = 1;
public def FISH:Integer = 2; 

public class Animal extends CustomNode {

    public var type:Integer = COW on replace {
        println( "animal = {type}");
    };
}

// On my Main.fx
var a:Animal;

Stage {
    title: "Application title"
    scene: scene = Scene {
        width: 640
        height: 480
        fill: javafx.scene.paint.Color.BLACK
        content: [
            a = Animal {
                type: Animal.BIRD 
            }
        ]
    }
}
 

After that, I could access them just the same as public static final ints in java.

Hope this helps someone else.

Cheers,

Fabricio
