JavaFX + Java

Tough to understand the code conversion :). I have seen the Java code of corresponding JavaFX code. Though its tough to map but we can see the correct correspondence. Let see this :

import javafx.ui.*;

Frame {
title: "Hello World JavaFX"
width: 200
content: Label {
text: "Hello World"
visible: true

and the corresponding Java Code:

import com.sun.javafx.runtime.Entry;
import com.sun.javafx.runtime.FXObject;
import com.sun.javafx.runtime.InitHelper;
import com.sun.javafx.runtime.Public;
import com.sun.javafx.runtime.Static;
import com.sun.javafx.runtime.location.AbstractVariable;
import com.sun.javafx.runtime.location.BooleanVariable;
import com.sun.javafx.runtime.location.DoubleVariable;
import com.sun.javafx.runtime.location.ObjectVariable;
import com.sun.javafx.runtime.sequence.Sequence;
import javafx.ui.Frame;
import javafx.ui.Frame.Intf;
import javafx.ui.Label;
import javafx.ui.Label.Intf;

public class Hello
implements Hello.Intf, FXObject
public static Object javafx$run$(Sequence paramSequence)
Frame localFrame = new Frame(true);
localFrame.get$title().setFromLiteral("Hello World JavaFX");
Label localLabel = new Label(true);
localLabel.get$text().setFromLiteral("Hello World");

localLabel.initialize$(); localFrame.get$content().setFromLiteral(localLabel);


localFrame.initialize$(); return localFrame; }
public void initialize$() { addTriggers$(this); userInit$(this); postInit$(this); InitHelper.finish(new AbstractVariable[0]); }
public static void addTriggers$(Hello.Intf paramIntf) { }
public Hello() { this(false); initialize$(); }
public static void userInit$(Hello.Intf paramIntf) { }
public static void postInit$(Hello.Intf paramIntf) { }
public static void main(String[] paramArrayOfString)
throws Throwable { Entry.start(Hello.class, paramArrayOfString);

This I have done by generating the class file and then de-compiled the class file.

Frame of JavaFX - Frame localFrame = new Frame(true);
title and text of JavaFX
- localFrame.get$title().setFromLiteral(”Hello World JavaFX”);
- localLabel.get$text().setFromLiteral(”Hello World”);

Visibility of JavaFX - localFrame.get$visible().setAsBooleanFromLiteral(true);

Lot of code is written to support JavaFX environment, which is completely justifiable. Don’t able to get why methods are written with $. If any clue, please let us know also.
