Eclipse cannot support javafx by default. Perform the following operations to enable access to javafx

1. Right-click the project->BildPath->Configure Bild Path, select the Library tab, select Access rules, and click edit on the right.

Click add on the pop-up TypeAccessRules form, the Edit Access Rule form pops up, select Accessible for Resolution option, and fill in "javafx/**" for Rule Pattern option

This will allow you to use javafx directly in Eclipse.

Try writing a helloworld:

package start;
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.control.Label;
import javafx.scene.image.Image;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class start extends Application{
    public static void main( String[] args)
    {
        System.out.println("hello,world");
        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("HelloWorld!");  
               }  
           });  
             
           StackPane root = new StackPane();  
           root.getChildren().add(btn);  
           primaryStage.setScene(new Scene(root, 300, 250));  
           primaryStage.show();  
        }  

}

 

Note that there is a Gtk-Message on it that says "canberra-gtk-module" could not be loaded

The solution is as follows:

Open the terminal and execute the following command to install the module

sudo apt-get install libcanberra-gtk-module

 

 Run it again, live it up.
