如何在javafx密码字段中启用输入法

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.PasswordField;
import javafx.scene.layout.VBox;
import javafx.stage.Stage;

public class PasswordFieldExample extends Application {

    @Override
    public void start(Stage primaryStage) {
        PasswordField passwordField = new PasswordField();
        passwordField.setEditable(true);
        passwordField.setPromptText("请输入密码");

        passwordField.setOnMouseClicked(event -> {
            passwordField.requestFocus();
        });

        passwordField.setOnKeyPressed(event -> {
            String text = passwordField.getText();
            text += event.getText();
            passwordField.setText(text);
        });

        VBox root = new VBox(passwordField);
        Scene scene = new Scene(root, 300, 200);

        primaryStage.setTitle("JavaFX Password Field Example");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

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