Development host PC:
OS - Windows 8 Pro
Development Tools: NetBeans IDE 7.4
JDK: jdk 1.7.0_45
Raspberry Pi:
Model B with 8G SD Card
OS: Raspbian wheezy 2013-09-25
Memory Split: 64
Overclock: Medium 900MHz
Run in Text Console mode
java version 1.8.0-ea (build 1.8.0-ea-b117)
Steps:
- New a JavaFX Application in Netbeans, named "JavaFXHelloPi".
- Modify the Java code to add a button to exit.
package javafxhellopi;
import javafx.application.Application;
import javafx.application.Platform;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;
public class JavaFXHelloPi extends Application {
@Override
public void start(Stage primaryStage) {
Button btn = new Button();
btn.setText("Say 'Hello World'");
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
System.out.println("Hello World!");
}
});
Button btnExit = new Button();
btnExit.setText("Exit");
btnExit.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
Platform.exit();
}
});
VBox vBox = new VBox();
vBox.getChildren().addAll(btn, btnExit);
StackPane root = new StackPane();
root.getChildren().add(vBox);
Scene scene = new Scene(root, 300, 250);
primaryStage.setTitle("Hello World!");
primaryStage.setScene(scene);
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
- It run on Windows 8 like this:
- ftp the created jar, JavaFXHelloPi\dist\JavaFXHelloPi.jar, to Raspberry Pi.
- ssh to Raspberry Pi, run the jar by entering the command:
$ java -jar JavaFXHelloPi.jar
Remark:
It's just a personal experiment. For official steps, refer: https://wiki.openjdk.java.net/display/OpenJFX/OpenJFX+on+the+Raspberry+Pi
