The *JavaFX* *HTMLEditor* is an advanced HTML editor that enables the user to edit HTML easier than by writing the full HTML markup in text. The HTMLEditor contains a set of buttons that can be used to set the styles of the edited text WYSIWYG style. The JavaFX HTMLEditor is represented by the class `javafx.scene.web.HTMLEditor`. Here is a screenshot of a JavaFX HTMLEditor:

### Full HTMLEditor Example ###

Here is first a full JavaFX `HTMLEditor` example so you can see what using the `HTMLEditor` looks like in code:

import javafx.application.Application;
    import javafx.scene.Scene;
    import javafx.scene.layout.VBox;
    import javafx.scene.web.HTMLEditor;
    import javafx.stage.Stage;
    
    public class HtmlEditorExample extends Application {
    
        public static void main(String[] args) {
            launch(args);
        }
    
        public void start(Stage primaryStage) {
    
            HTMLEditor htmlEditor = new HTMLEditor();
    
            VBox vBox = new VBox(htmlEditor);
            Scene scene = new Scene(vBox);
    
            primaryStage.setScene(scene);
            primaryStage.setTitle("JavaFX App");
    
            primaryStage.show();
        }
    }

### Create an HTMLEditor ###

Before you can use a JavaFX `HTMLEditor` in your code, you must first create an instance of it. Here is an example of creating an instance of a JavaFX `HTMLEditor`:

HTMLEditor htmlEditor = new HTMLEditor();

### Get HTML From HTMLEditor ###

Sooner or later you will probably want to obtain the HTML text that was edited in the `HTMLEditor` by the user. You obtain the HTML from the `HTMLEditor` via its `getHtmlText()` method. Here is an example of getting the HTML from a JavaFX `HTMLEditor` instance:

String htmlText = htmlEditor.getHtmlText();

As you can see, the HTML is returned as a standard [Java String][].

### Set HTML in HTMLEditor ###

You can also set the HTML to be edited in a JavaFX `HTMLEditor` via its `setHtmlText()` method. Here is an example of setting the HTML to be edited in a JavaFX `HTMLEditor` instance:

String htmlText = "<b>Bold text</b>";
    
    htmlEditor.setHtmlText(htmlText);
