CEF3: How to get V8 context and global object?

[tuma]

Hi,

I need to get get global object to invoke some JS function. The code that was working in CEF1 doesn't work now. It gives me "GetV8Context cannot be called from the browser process" error.

I am trying to invoke this from OnLoadEnd call back.
GetMainFrame()->GetV8Context()->GetGlobal();

What is the right way to do it?

I played around in cefclient code. It seems like these are accessible only from renderer process only. If I debug RENDER process and put break point in OnContextCreate, it hits there and I am able to call GetGlobal().

I have some code in BROWSER process which need to access and manipulate the V8 context and dom objects.

So do we need to do kind of inter-process communication from browser process to render process to perform any task in V8? Is there any mechanism that CEF3 provides for this purpose?

Yes, use SendProcessMessage with an asynchronous JS API. See http://www.chromium.org/developers/desi ... design-doc for example API design.

Is there any way to make synchronous call from render process to browser process? I am implementing a CefV8Handler in render process to expose some custom function to Java script. In this I have to make some query to browser process and get response synchronously. How to do this?
