# clojure-minimal-javafx

A Clojure application that implements the very short program

defined in the JavaDocs for [`javafx.application.Application`][1]:

```

import javafx.application.Application;

import javafx.scene.Group;

import javafx.scene.Scene;

import javafx.scene.shape.Circle;

import javafx.stage.Stage;

public class MyApp extends Application {

    public void start(Stage stage) {

        Circle circ = new Circle(40, 40, 30);

        Group root = new Group(circ);

        Scene scene = new Scene(root, 400, 300);

        stage.setTitle("My JavaFX Application");

        stage.setScene(scene);

        stage.show();

    }

}

```

### Code Notes

- The addition of `:main` and `:aot` to `project.clj` is required due

to the self-reference in the `-main` function.

- The Java code uses a variadic argument constructor for `javafx.scene.Group`.

In Clojure, it is challenging to invoke this constructor. Instead, the 

no-argument constructor is used, and the circle is added post-creation.

- The generated Application class needs to be passed to `launch()` as functions

are inner classes in Java. Also, hyphens in namespaces are converted

to underscores for packages and files.

## Usage

```

   lein run

```
