Scene类

窗口结构

• scene类基本使用

  Button button = new Button("Hello World");  
  Group group = new Group();  
  group.getChildren().add(button);  
  Scene scene = new Scene(group);  
  primaryStage.setScene(scene);  
  primaryStage.setTitle("JavaFX");  
  primaryStage.setWidth(500);  
  primaryStage.setHeight(500);  
  primaryStage.show();
  

  

• 修改鼠标样式 scene.setCursor(Cursor.HAND);

• 用图片设置鼠标样式

  URL resource = getClass().getClassLoader().getResource("images/p.png");  
  String cursor = resource.toExternalForm();  
  scene.setCursor(Cursor.cursor(cursor));
  

• 默认浏览器打开网页

  HostServices hostServices = getHostServices();  
  hostServices.showDocument("https://www.baidu.com");
