如何在窗口中创建LibGDX文本输入？(无弹出窗口)

Stage stage = new Stage();

TextField textField = new TextField("", skin);
textField.setPosition(x, y);
textField.setSize(width, height);

stage.addActor(textField);

Gdx.input.setInputProcessor(stage);

stage.act();
stage.draw();

public class MyGame extends ApplicationAdapter {
    private Stage stage;
    private TextField textField;
    private Skin skin;

    @Override
    public void create() {
        stage = new Stage();
        Gdx.input.setInputProcessor(stage);

        skin = new Skin(Gdx.files.internal("skin/uiskin.json"));

        textField = new TextField("", skin);
        textField.setPosition(100, 100);
        textField.setSize(200, 30);

        stage.addActor(textField);
    }

    @Override
    public void render() {
        Gdx.gl.glClearColor(0, 0, 0, 1);
        Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);

        stage.act();
        stage.draw();
    }

    @Override
    public void dispose() {
        stage.dispose();
        skin.dispose();
    }
}
