cursor with a rectangle shape for a text entry / javafx

Question

I would like to implement a text input using javafx. The cursor looks like a black rectangle (for people with low vision). It seems impossible with a text area or a text field. The mouse shape can be an arrow for example. Can you give ideas to implement this function ?

Here is full example

import com.sun.javafx.scene.control.skin.TextFieldSkin;
    import javafx.application.Application;
    import javafx.geometry.Insets;
    import javafx.scene.Scene;
    import javafx.scene.control.TextField;
    import javafx.scene.layout.VBox;
    import javafx.scene.paint.Color;
    import javafx.stage.Stage;

    public class CaretColorizer extends Application {

        @Override
        public void start(Stage stage) throws Exception {
            TextField redCaretTextField = new TextField("Big black caret");
            redCaretTextField.setSkin(
                    new TextFieldCaretControlSkin(
                            redCaretTextField,
                            Color.RED
                    )
            );

            VBox layout = new VBox(10, redCaretTextField);

            layout.setPadding(new Insets(10));
            stage.setScene(new Scene(layout));

            stage.show();
        }

        public class TextFieldCaretControlSkin extends TextFieldSkin {
            public TextFieldCaretControlSkin(TextField textField, Color caretColor) {
                super(textField);


                caretPath.strokeProperty().unbind();
                caretPath.fillProperty().unbind();
                caretPath.setStrokeWidth(10);
                caretPath.setStroke(Color.BLACK);
                caretPath.setFill(Color.BLACK);
            }
        }

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