1、窗口风格设置：（primaryStage.initStyle(StageStyle);）
StageStyle有几种类型
1) DECORATED——白色背景，带有最小化/最大化/关闭等有操作系统平台装饰（ 默认设置）
2) UNDECORATED——白色背景，没有操作系统平台装饰
3) TRANSPARENT——透明背景，没有操作系统平台装饰
4) UTILITY——白色背景，只有关闭操作系统平台装饰
5) UNIFIED——有操作系统平台装饰，消除装饰和内容之间的边框，内容背景和边框背景一致
2、自定义标题栏：首先去掉系统自带的标题栏。直接设置窗口风格，设置为没有操作系统平台装饰的，然后加上自定义布局，直接上代码
