这是我的代码。谁能帮我添加一个“停止”按钮来停止加载页面，添加标签来加载多个页面，并在我的浏览器中安装 Adobe Flash Player 以便我可以访问 Youtube(www.youtube.com)。

谢谢你帮助我。

我正在使用 Netbeans。当我运行我的应用程序时，这就是结果。

谁能告诉我为什么？

add tab to load multiple page

willow browser是一个选项卡式 JavaFX 浏览器示例项目 - 查看它以了解如何完成。

add a "Stop" Button to stop loading page,

您可以尝试在按钮的操作处理程序中执行 webView.getEngine().getLoadWorker().cancel();。我不确定 WebEngine 是否会尊重取消请求。

install Adobe Flash Player to my browser

你不能 - WebView 不支持 Flash 等插件。

access Youtube

使用 YouTube 的 html5 兼容视频播放界面，而不是基于 flash 的界面。

我创建了一些 sample code to play YouTube Videos in a WebView .

WARNING: bad driver version detected, device disabled. Please update your driver to at least version 8.15.10.2302

您的显示驱动程序已过时，不符合使用 JavaFX 的最低要求 - 您应该将其更新到较新的版本。
