[FIXED] Is it possible to add a Bulletted list mode in TextArea JavaFX

Issue

Just like in Word or WYSIWYG editor, I want the ability to make TextArea perform a simple bullet list.

Solution

I was able to figure it out using RichTextFX StyleClassedTextArea :

public static final String BULLET_CODE = "  \u2022\t";

        textArea.setOnKeyPressed(event ->
        {
            KeyCode code = event.getCode();
            if (KeyCode.ENTER.equals(code))
            {

                textArea.moveTo(textArea.getCaretPosition() - 1);
                textArea.selectParagraph();
                if (StringUtils.startsWith(textArea.getSelectedText(), BULLET_CODE))
                {
                    textArea.moveTo(textArea.getCaretPosition() + 1);

                    textArea.lineStart(NavigationActions.SelectionPolicy.CLEAR);
                    textArea.insertText(textArea.getCaretPosition(), BULLET_CODE);
                } else
                {
                    textArea.moveTo(textArea.getCaretPosition() + 1);

                }
                textArea.deselect();

            }
        });

And adding a button that inserts a bullet:

        addBullet.setOnAction((ActionEvent t) ->
        {
            textArea.selectLine();
            if (!StringUtils.startsWith(textArea.getSelectedText(), BULLET_CODE))
            {
                textArea.deselect();
                textArea.lineStart(NavigationActions.SelectionPolicy.CLEAR);
                textArea.insertText(spellCheckArea.getTextArea().getCaretPosition(), BULLET_CODE);
                textArea.lineEnd(NavigationActions.SelectionPolicy.CLEAR);
            }
            textArea.deselect();
            textArea.requestFocus();
        });
