Question

组件开发，使用如下代码新建场景窗口，在执行这一句时SuperMap桌面直接崩了，

IFormScene formScene = (IFormScene) FormUtilities.fireNewWindowEvent(WindowType.SCENE);

产生错误信息

您好，出现JVM崩溃是因为 FormUtilities.fireNewWindowEvent(WindowType.SCENE) 接口必须在 UI 线程中执行，根据您的代码逻辑，有以下 2 中调整方案：

1. 直接将截图中的代码逻辑提出子线程；

   public void run() {
   	IFormScene formScene = (IFormScene) FormUtilities.fireNewWindowEvent(WindowType.SCENE);
   	SceneControl sceneControl = formScene.getSceneControl();
   	Scene scene = sceneControl.getScene();
   	scene.refresh();
   	scene.setLookAt(scene.getLookAt());
   }

2. 将截图中的代码逻辑全部放入 SwingUtilities.invokeLater 里面。

   public void run() {
   	new Thread(()->{
   		SwingUtilities.invokeLater(()->{
   			IFormScene formScene = (IFormScene) FormUtilities.fireNewWindowEvent(WindowType.SCENE);
   			SceneControl sceneControl = formScene.getSceneControl();
   			Scene scene = sceneControl.getScene();
   			scene.refresh();
   			scene.setLookAt(scene.getLookAt());
   		});
   	}).start();
   }

希望可以帮到您。
