Closing CEF while multi_threaded_message_loop = true

[akovar]

Hello,

I am trying to properly close MFC app using CEF, but there are still some issues I do not understand. (We are using CEF with multi_threaded_message_loop = true)

- First when OnClose msg comes I try to close browser using host->CloseBrowser(false), this is OK and DoClose(...) callback is called and I return false and I prevent MFC CMainFrame to close
- Then CEF system sends a WM_CLOSE message to mainframe window, and then I, just to be sure, check if I really can close so I call host->TryCloseBrowser() but it always return false. When I tried to find out the reason, I ended up in CefBrowserHostImpl::TryCloseBrowser(). I am calling this from main thread so it does not really check if I can close and always returns false (because of CEF_CURRENTLY_ON_UIT )

Is there any other way how to check if I can close CEF?

You will need to track the closing status yourself in the DoClose method instead of calling TryCloseBrowser. See the example implementation in cefclient (usage of the IsClosing method).
