如果我不使用FXML,那么它可以工作(:-D):

我的问题是:如何在任何地方使用stage变量? 还是有其他解决办法? JavaFX很酷,只是遗憾没有一个好的IDE(带有GUI设计器)。 您可以忘记的JavaFX场景生成器和使用FXML是愚蠢的!:-( 但是,我不知道JavaFX场景生成器的替代方案。 没有创建GUI设计器的GUI对于大型程序来说是愚蠢的:-(

请帮帮我

在互联网上我的问题没有答案,这让我很惊讶。(既没有德语教程,也没有英语教程)

对不起,我的英语不好。 我学习这门语言:-)。 我也是Java初学者:-)

我希望我没有忘记任何事情


谢谢:-)

在类中声明一个静态阶段变量,并将primaryStage分配给它

public class Book extends Application implements Initializable
{
    public static Stage stage;
    @ Override
    public void start (Stage primaryStage) throws IOException
    {
        stage = primaryStage;
        ...
    }
    ...
    @ FXML
    public void fullscreen (ActionEvent event)
    {
        stage.setFullScreen(true);
    }
}

非常感谢!:-)
