JavaFX Hello World

It’s fun to learn new languages and althrough I prefer Actionscript 3 I’m giving JavaFX a shot because it’s been developerd by sun the guys that brought us JAVA. Ive heard of the ten minute JavaFX tutorial. This will be like a three minute tutorial. This screenshot gives an idea of how simple this will be:

See, it says “Hello World” in the viewport, and “Hello World” in the window frame. Bellow is the code that makes this happen.

package HelloWorld;

/*Import all of the packages we'll be using. */
import javafx.stage.Stage;
import javafx.scene.Scene;
import javafx.scene.text.Text;
import javafx.scene.text.Font;

/*The stage is the window. */
Stage {
    title: "Hello World"
    width: 250
    height: 80

/*The scene is the viewport. The stage has a variable named scene that is Scene object. */
    scene: Scene {

/* The scene has some content inside it, in this case is will be the "Hello World" text.*/
        content: [
/* When you're programming be prepared to think of everything. We need to program our text by giving it a size and a family*/
            Text {
                font : Font {
                    name: "Sans Serif"
                    size : 16
                }
/*Here is where we answer the question of where we want to place the text we've just created in the viewport in number of pixels*/
                x: 10
                y: 30
/*The content of our text box will be some text right.*/
                content: "Hello World"
            }/*end text*/
        ]/*end scene content*/
    }/*end scene*/
}/*end Stage*/
