From 0000000000000000000000000000000000000000 Mon Sep 17 00:00:00 2001 From: Cheng Zhao Date: Thu, 4 Oct 2018 14:57:02 -0700 Subject: fix: also propagate fullscreen state for outer frame When entering fullscreen with Element.requestFullscreen in child frames, the parent frame should also enter fullscreen mode too. Chromium handles this for iframes, but not for webviews as they are essentially main frames instead of child frames. This patch makes webviews propagate the fullscreen state to embedder. Note that we also need to manually update embedder's `api::WebContents::IsFullscreenForTabOrPending` value. diff --git a/content/browser/renderer_host/render_frame_host_impl.cc b/content/browser/renderer_host/render_frame_host_impl.cc index 15011d7efd9f1f239e425904c8c22511e49dff88..b9ecdb1d4fde213ea48133285a346557624d1e7f 100644 --- a/content/browser/renderer_host/render_frame_host_impl.cc +++ b/content/browser/renderer_host/render_frame_host_impl.cc @@ -7223,6 +7223,17 @@ void RenderFrameHostImpl::EnterFullscreen( } } + // Entering fullscreen from webview should also notify its outer frame. + if (frame_tree_node()->render_manager()->IsMainFrameForInnerDelegate()) { + RenderFrameProxyHost* outer_proxy = + frame_tree_node()->render_manager()->GetProxyToOuterDelegate(); + DCHECK(outer_proxy); + if (outer_proxy->is_render_frame_proxy_live()) { + outer_proxy->GetAssociatedRemoteFrame()->WillEnterFullscreen( + options.Clone()); + } + } + // Focus the window if another frame may have delegated the capability. if (had_fullscreen_token && !GetView()->HasFocus()) GetView()->Focus();
