php - 我正在尝试使用Elementor Typography Control。但这不起作用

Question

现在，我正在使用This For Elementor Control。
我尝试了近10次，但是没有用。
有人请帮助我。我不知道为什么它不起作用。其他控件工作正常。都准备好了。只有版式控件不起作用。

        //slide control
        $this->start_controls_section(
            'hero_area_section',
            [
                'label' => __( 'Content', 'plugin-name' ),
                'tab' => \Elementor\Controls_Manager::TAB_CONTENT,
            ]
        );

$this->add_control(
        'bg', [
            'label' => __( 'Background', 'plugin-domain' ),
            'type' => \Elementor\Controls_Manager::MEDIA,
            'label_block' => true,
        ]
    );
  $this->add_control(
        'title', [
            'label' => __( 'Title', 'plugin-domain' ),
            'type' => \Elementor\Controls_Manager::TEXTAREA,
            'label_block' => true,
        ]
    );
   $this->add_control(
        'cap', [
            'label' => __( 'Caption', 'plugin-domain' ),
            'type' => \Elementor\Controls_Manager::TEXTAREA,
            'label_block' => true,
        ]
    );

  $this->add_group_control(
    Group_Control_Typography::get_type(),
    [
        'name' => 'title_typography',
        'label' => __( 'Title Typography', 'my-plugin-domain' ),
        'scheme' => Scheme_Typography::TYPOGRAPHY_1,
        'selector' => '{{WRAPPER}} h3',

    ]
);

$this->end_controls_section();```



And this is not working and showing this Erro:

在Group_Control_Typography使用\ Elementor \之前，您在上一节中所做的工作。
