如何在Monogame项目中实现Awesomium 1.7.4.2？
我试图在我的monogame项目中渲染渲染浏览器，用于绘制一些界面和东西。 我在过去使用旧版本的awesomium完成了这项工作，没有任何问题。 但我无法弄清楚如何在这个新版本中正确地初始化awesomium，无论我如何尝试它，我都会收到错误。 据我所知，我需要调用WebCore.Run（）一次，而不是WebCore.Update（），但我得到该方法的variusexception。
以下是我到目前为止所遵循的步骤：
- 安装Awesomium 1.7.4.2
- 我的项目中的Refrenced
\1.7.4.2\wrappers\Awesomium.NET\Assemblies\Packed\Awesomium.Core.dll
以下是我的一些尝试：
WebCore.Initialize(new WebConfig()); WebCore.Run(); //Error: Starting an update loop on a thread with an existing message loop, is not supported.
WebCore.Initialized += (sender, e) => { WebCore.Run(); }; WebCore.Initialize(new WebConfig()); WebView WebView = WebCore.CreateWebView(500, 400); //Error: Starting an update loop on a thread with an existing message loop, is not supported.
WebCore.Initialize(new WebConfig()); WebView WebView = WebCore.CreateWebView(500, 400); WebView.Source = new Uri("http://www.google.com"); WebView.DocumentReady += (sender, e) => { JSObject js = WebView.CreateGlobalJavascriptObject("w"); }; // No errors, but DocumentReady is never fired..
我还设法得到NullRefrence错误，如果我在调用WebCore.Run（）之前等待Thread.Sleep（400），它只是进入WebCore.Run（）并且永远不会完成该行。
我该如何设置？ 在任何地方都找不到任何例子。 所有在线示例仍然告诉您使用更新已过时
我刚刚开始工作，你必须创建一个新线程，然后调用Run，然后监听由WebCore引发的事件，届时将创建一个新的SynchronizationContext。 然后，您希望在主线程上保留对该上下文的引用…
Thread awesomiumThread = new System.Threading.Thread(new System.Threading.ThreadStart(() => { WebCore.Started += (s, e) => { awesomiumContext = SynchronizationContext.Current; }; WebCore.Run(); })); awesomiumThread.Start(); WebCore.Initialize(new WebConfig() { });
…然后，您可以使用该SynchronizationContext调用所有WebView方法…
awesomiumContext.Post(state => { this.WebView.Source = "http://www.google.com"; }, null);
我会用未来的编辑来整理这个，但为了让你们开始，这是我的组件……
