Dev Tools in CefSharp sample project

[DenStoreKlinge]

Hi

I downloaded the code/lib today and started playing with it. Looks cool. I noticed that in the Winform example, I can start a Dev Tool application, that fx shows the elements in a waterfall display, when downloading the website (e.g. shows each element as it is downloaded, it's size, download time and so on).

I would like to try build a small console that do something similar, just displays the properties/data as text for now. I assume I neeed to catch some events for each element downloaded, giving me the properties on the element.

Any suggestions on where to start in CefSharp and I would be extremely happy if someone could give me a C# code sample.

Thanks in advance.

Take a look at the IRequestHandler interface. You can implement that and then supply an instance of your implementation to the corresponding property on the webview you're using.

Hi Jack

Thanks, that got me started. I looked into the samples and tried to construct a class based on what I found. This is what I came up with:

    public class CEFTest : IRequestHandler
    {
        public WebView view;

        public CEFTest(string _URL)
        {
            CefSharp.BrowserSettings browserSettings = new CefSharp.BrowserSettings();
            view = new CefSharp.WinForms.WebView("", browserSettings);
            view.RequestHandler = this;

            if (view.IsBrowserInitialized)
            {
                view.Load(_URL);
            }
        }

        public bool OnBeforeBrowse(IWebBrowser browser, IRequest request, NavigationType naigationvType, bool isRedirect)
        {
            return true;
        }

        public bool OnBeforeResourceLoad(IWebBrowser browser, IRequestResponse requestResponse)
        {
            return true;
        }

        public void OnResourceResponse(IWebBrowser browser, string url, int status, string statusText, string mimeType, System.Net.WebHeaderCollection headers)
        {
        }
    }

When I call the CEFTest constructor from my app, IsBrowserInitialized is always false. If I don't have this check, the Load method fails with "Browser not initialized". If I set the URL into the WebView constructor, this wont make a difference. I guess the WebView is missing some initialize part, which it would probably normally get from an app initialier for added components.
