Bug 185676 – [WPE] Implement and enable FULLSCREEN_API

• Status: RESOLVED
• Resolution: FIXED
• Component: WPE WebKit

[Carlos Alberto Lopez Perez]

Yesterday I discovered doing tests with WPE on video sites (e.g: youtube) that WPE doesn't implement FULLSCREEN_API.

This HTML5 API is needed for any website that wants to show content full-screen.

Is mostly useful for playing videos, although it can be used to show any content full-screen.

It looks enabling this on WPE is not difficult (I think I already have it working)  ... so I'll submit a patch.

I think so, its a RefPtr. 

And I see how other callers of this code are not null checking for it, for example in the WebKitGTK+ impl at https://trac.webkit.org/browser/trunk/Source/WebKit/UIProcess/API/gtk/WebKitWebViewBase.cpp?rev=225900#L1239
