My question<\/a> was:<\/p>\n

How to hide the cursor in Awesomium – I tried this:<\/p>\n

<awe:WebControl x:Name=\"webBrowser\" Cursor=\"None\" Source=\"http:\/\/example.com\/\"\/><\/pre>\n
but the cursor still shows.<\/p>\n
I figured that I could alter the CSS of the page by adding the following line:<\/p>\n
*{\r\n    cursor: none;\r\n}<\/pre>\n
But, is there a solution for when I don’t have the access to the actual page that I’m showing?<\/p>\n
The answer, by user Sjoerd2228888<\/a>, was:<\/p>\n
You can use a ResouceInterceptor and manipulate the page on the fly to insert custom CSS.<\/p>\n
EDIT:<\/p>\n
The following implementation should do the job. (It assumes there is a text.css file)<\/p>\n
class ManipulatingResourceInterceptor : IResourceInterceptor\r\n{\r\n    public ResourceResponse OnRequest(ResourceRequest request)\r\n    {\r\n        Stream stream = null;\r\n\r\n        \/\/do stream manipulation\r\n        if (request.Url.ToString() == \"http:\/\/your.web.url\/test.css\")\r\n        {\r\n            WebRequest myRequest;\r\n            myRequest = WebRequest.Create(request.Url);\r\n            Stream webStream = myRequest.GetResponse().GetResponseStream();\r\n            StreamReader webStreamReader = new StreamReader(webStream);\r\n            string webStreamContent = webStreamReader.ReadToEnd();\r\n\r\n            stream = webStream;\r\n\r\n            string extraContent = \"*{cursor: none;}\";\r\n\r\n            webStreamContent += extraContent;\r\n            byte[] responseBuffer = Encoding.UTF8.GetBytes(webStreamContent);\r\n\r\n            \/\/ Initialize unmanaged memory to hold the array.\r\n            int responseSize = Marshal.SizeOf(responseBuffer[0]) * responseBuffer.Length;\r\n            IntPtr pointer = Marshal.AllocHGlobal(responseSize);\r\n            try\r\n            {\r\n                \/\/ Copy the array to unmanaged memory.\r\n                Marshal.Copy(responseBuffer, 0, pointer, responseBuffer.Length);\r\n                return ResourceResponse.Create((uint)responseBuffer.Length, pointer, \"text\/css\");\r\n            }\r\n            finally\r\n            {\r\n                \/\/ Data is not owned by the ResourceResponse.
