Posted: Wed May 23, 2012 5:46 am Post subject: JavaFX application development with Netbeans on Linux (OpenSuse)

Hi:
My Netbeans and associated information are as below:
- Product Version: NetBeans IDE 7.1.2 (Build 201204101705)
- Java: 1.7.0; Java HotSpot(TM) Client VM 21.0-b17
- JavaJX: javafx-sdk2.1.0
- System: Linux version 3.1.10-1.9-desktop running on i386 (OpenSuse 12.1)

Created a JavaFX "Hello World" application which builds without any error. However, if I run (from Netbeans), it gives me an output which only shows the frame (stage in JavaFX term ?) no buttons, as seen here:http://javafxerror.blogspot.ca/

Please let me know how to resolve this problem.

Thanks.

The runtime errors logs:

SEVERE: javafx.scene.control.Control impl_processCSS The -fx-skin property has not been defined in CSS for Button[id=null, styleClass=button]

The source code is:

Code:

/*

* and open the template in the editor.
*/
package myjavafx;

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

/**

* @author jrahman
*/
public class MyJavaFX extends Application {

/**
* @param args the command line arguments
*/
public static void main(String[] args) {
launch(args);
}

@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World!");
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!");
}
});

StackPane root = new StackPane();
root.getChildren().add(btn);
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
}
}
