API for multiple renderer processes

[gshaibi]

Hi,
I've upgraded CEF from 3683 to 4044, and noticed that now there may be several render processes per window with iframes(different process for each domain).
Until now, I've used your API to get information regarding the renderers state (such as OnRenderViewReady and OnRenderProcessTerminated) which were called every time a renderer was spawned, but it seems that now its now the case, and these methods are called only for the main renderer.
How can I get it to work with all the renderers?

Thanks!

See here which explains about the multiple renderer processes.

What purpose are you using these callbacks for?

[gshaibi]

I need these functions for various reasons, such as sending initial configurations for each renderer that spawns, creating a watchdog for it etc.

For renderer configuration purposes you can use the extra_info passed to CreateBrowser.

Thanks for the quick reply!
In my case, extra_info at CreateBrowser will not be enough because I need to send a dynamic configuration based on the domain of the renderer, which I don't know yet at the browser creation time.
I also need to get the pid of each renderer that spawns, when it is spawned. How can I do that?

What, specifically, are you configuring? You can send the config via an IPC message after the navigation had committed, as indicated by OnLoadEnd or OnLoadingStateChange(isLoading=false).

You can add code in the main() function for sub-processes before calling CefExecuteProcess. The renderer process is indicated by “--type=renderer” on the command line.
