java - 关闭运行 OpenGL 内容的 JavaFX 窗口时出现奇怪的错误

Question

我有一个 JavaFX 应用程序，其中包含一个带有 OpenGL 应用程序的 SwingNode。大多数时候，一切都很好，但有时当我关闭窗口时，我会收到此错误:

我搜索了它可能的内容，但找不到任何内容。有人知道为什么会发生这种情况吗？这是我用来关闭应用程序的代码:

// Close operation
primaryStage.setOnCloseRequest(new EventHandler<WindowEvent>() {
    @Override
    public void handle(WindowEvent t) {
        Platform.exit();
        System.exit(0);
    }
});

Answer 1

我不确定，但是您正在执行 Platform.exit() ，这会强制 Application.lauch() 返回，因此您应该将 System.exit() 放在 main() 函数中，因为当您执行 Platform.exit() 时，JavaFX 运行时会关闭。 exit() 和 stop() 方法被调用，但同时 System.exit() 被调用
