Create an HTML Editor

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
 /*from w w w  .  j  a  v  a2  s . co m*/
public class Main extends Application {
 
    @Override
    public void start(Stage stage) {
        HTMLEditor htmlEditor = new HTMLEditor();
        htmlEditor.setPrefHeight(245);
        Scene scene = new Scene(htmlEditor);       
        stage.setScene(scene);
        stage.show();
    } 
    public static void main(String[] args) {
        launch(args);
    }
}

The code above generates the following result.

HTML Content

To set content to HTMLEditor class, use the setHtmlText method. 

htmlEditor.setHtmlText(INITIAL_TEXT);

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
 //from   w  w w. j ava2 s .c om
public class Main extends Application {
 
    @Override
    public void start(Stage stage) {
        HTMLEditor htmlEditor = new HTMLEditor();
        htmlEditor.setPrefHeight(245);
        String INITIAL_TEXT = "Lorem ipsum dolor sit "
            + "amet, consectetur adipiscing elit. Nam tortor felis, pulvinar "
            + "aliquam sagittis gravida eu dolor. Etiam sit amet ipsum "
            + "sem.";
        htmlEditor.setHtmlText(INITIAL_TEXT);
        Scene scene = new Scene(htmlEditor);       
        stage.setScene(scene);
        stage.show();
    } 
    public static void main(String[] args) {
        launch(args);
    }
}

The code above generates the following result.

Format

We can use the HTML tags in this string to apply specific formatting for the initially rendered content. 

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
 /* w w  w. j  a v  a  2  s.c  om*/
public class Main extends Application {
 
    @Override
    public void start(Stage stage) {
        HTMLEditor htmlEditor = new HTMLEditor();
        htmlEditor.setPrefHeight(245);
        String INITIAL_TEXT = "Lorem ipsum dolor sit "
            + "amet, consectetur adipiscing elit. <i>Nam tortor felis</i>, pulvinar "
            + "<UL><li>a</li><li>a</li><li>a</li></UL>"
            + "aliquam sagittis gravida <b>eu dolor</b>. Etiam sit amet ipsum "
            + "sem.";
        htmlEditor.setHtmlText(INITIAL_TEXT);
        Scene scene = new Scene(htmlEditor);       
        stage.setScene(scene);
        stage.show();
    } 
    public static void main(String[] args) {
        launch(args);
    }
}

Obtaining HTML Content

import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
import javafx.scene.web.HTMLEditor;
import javafx.stage.Stage;
 //from w  ww .  ja  v a2  s  .  c  om
public class Main extends Application {
 
    @Override
    public void start(Stage stage) {
        HTMLEditor htmlEditor = new HTMLEditor();
        htmlEditor.setPrefHeight(245);
        String INITIAL_TEXT = "Lorem ipsum dolor sit "
            + "amet, consectetur adipiscing elit. <i>Nam tortor felis</i>, pulvinar "
            + "<UL><li>a</li><li>a</li><li>a</li></UL>"
            + "aliquam sagittis gravida <b>eu dolor</b>. Etiam sit amet ipsum "
            + "sem.";
        htmlEditor.setHtmlText(INITIAL_TEXT);
        
        Button showHTMLButton = new Button("Produce HTML Code");
        
        showHTMLButton.setOnAction((ActionEvent arg0) -> {
          System.out.println(htmlEditor.getHtmlText());
        });
        
        VBox vbox = new VBox();
        vbox.getChildren().addAll(htmlEditor,showHTMLButton);
        Scene scene = new Scene(vbox);       
        stage.setScene(scene);
        stage.show();
    } 
    public static void main(String[] args) {
        launch(args);
    }
}

The code above generates the following result.
