Implement OnFullscreenModeChange

[wrightpt]

My goal is to get the browser to show fullscreen without having to hit the fullscreen button at the bottom right of the video window.


Enter url in simple_app.cc file:

Code: Select all

 if (url.empty())
    url = "https://www.youtube.com/watch?v=0DQup4hd1_o";


override the OnFullscreenModeChange method in simple_handler.h:

Code: Select all

virtual  void OnFullscreenModeChange(CefRefPtr<CefBrowser> browser, bool fullscreen) OVERRIDE;

Implement in simple_handler.cc

Code: Select all

void SimpleHandler::OnFullscreenModeChange(CefRefPtr<CefBrowser> browser, bool fullscreen) {
    // CEF_REQUIRE_UI_THREAD();
    LOG(INFO) << " OnFullscreenModeChange " << "fullscreenchanged" ;
   
    if (fullscreen != true){
   
    fullscreen = true;

    DLOG(INFO) << "fullscreen = " << fullscreen ;
   
 // return ;
      }
}


Also implemented it at the same time within this method:

Code: Select all

CefRequestHandler::ReturnValue SimpleHandler::OnBeforeResourceLoad(
      CefRefPtr<CefBrowser> browser,
      CefRefPtr<CefFrame> frame,
      CefRefPtr<CefRequest> request,
      CefRefPtr<CefRequestCallback> callback)
{

  //implemented here:
    CefDisplayHandler::OnFullscreenModeChange(browser,true);

it compiles, runs, but there is no behaviour change. Could it be how I am entering the url in the code?

am i even close?

You need to implement fullscreen window changes in your application. Look at cefclient for an example.

Are you also the "JimmyH" account?

[wrightpt]

Thank you!!!

yes, I am the JimmyH account. sorry, You can delete it. i didn't know if this was an annoying question. so i didn't want to risk my, what I feel may be an already somewhat tattered reputation. wont happen again

Also, I do not want to change the size of the actual browser. just be fullscreen within the browser window that is already there.

This forum exists for asking questions. No reason to feel bad about it

When you click the fullscreen button on an HTML5 video that video should occupy the whole window. The size of that window won't change unless your client implementation decides to change it. When you click the fullscreen button on a Flash video then you will get a full-screen window if you're not using off-screen rendering.

Still researching this.

--when I pull up a youtube video in cefclient and hit full screen, it changes the size of the entire browser to match my screen.

--but when in cefsimple, it goes fullscreen within the same window and the browser window size does not change.



I am looking to have the behaviour of cefsimple but doing it programmatically instead of with my mouse click. will propose a way to do this in my next post, still analyzing how the onfullSceen process works.

in the earlier post you mentioned "implement fullscreen window changes in your application," I do not think this will help because that is not my ultimate goal. I just want the full screen to happen upon loading and not having to click the fullscreen button with the browser window remaining the same size (not taking up the full screen of my monitor).

The below javascript function actually being called on the youtube webpage is what allows the video to go fullscreen:

Is it possible to extend CefV8Context class and use this pure virtual Eval function to execute the below function?

Code: Select all

hz=function(a){if($h())if(a.isFullscreen())bi(a.Da());else{a=a.Da();var b=Yh(["requestFullscreen","webkitRequestFullscreen","mozRequestFullScreen","msRequestFullscreen"],a);b&&b.call(a)}else a.za("onFullscreenToggled",a.isFullscreen())};

You can execute JavaScript as described at https://bitbucket.org/chromiumembedded/ ... gration.md
