Editor does not contain main

[Rigo Gomez]

I am using Eclipse and I am trying to run this :

import javafx.application.*;

import javafx.stage.*;
import javafx.scene.*;
import javafx.scene.layout.*;
import javafx.scene.control.*;

public class Hi extends Application {
	public static void main (String[]args){
		launch (args);

	
	@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");
			}
		}
		
	}

});
	StackPane root = new StackPane();
	root.getChildren().add(btn);
	
	Scene scene = new Scene(root,300,250);
	
	primaryStage.setTitle("Hello World");
	primaryStage.setScene(scene);
	primaryStage.show();
	}
	
	
		
	}
}

But a it's stating : Editor does not contain main in the error
trying to figure out if I installed the javaFx correctly in Eclipse
or am I doing something wrong !

Hello Rigo, welcome to CodeRanch!

You replied to a different unrelated topic. I put your post in a new topic. I also put code tags around your code so that it's easier to read.

Now, I'm not sure what error you're getting, you might want to copy an paste the exact error message, but I can tell that the structure of your code is wrong. Your braces don't match up nicely, and it appears you have a start() method inside your main() method. I don't think this is as intended.

To understand Stephan van Hulst's comment regarding braces, compare your code to the sample hello world application from Oracle:
https://docs.oracle.com/javase/8/javafx/get-started-tutorial/hello_world.htm

package helloworld;
 
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;
 
public class HelloWorld 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!");
            }
        });
        
        StackPane root = new StackPane();
        root.getChildren().add(btn);

        Scene scene = new Scene(root, 300, 250);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}
