<h3>Log Message</h3>
<pre>UIProcess needs to know the color of the page's extended background
https://bugs.webkit.org/show_bug.cgi?id=129004
Source/WebCore:
Reviewed by Brent Fulgham.
This patch adds a new ChromeClient function,
pageExtendedBackgroundColorDidChange() which will be called whenever the extended
background color has changed.
New function.
* page/ChromeClient.h:
(WebCore::ChromeClient::pageExtendedBackgroundColorDidChange):
Store the extended background color in a member variable so that we can know if it
changed even if we do not have an m_layerForOverhangAreas.
* rendering/RenderLayerCompositor.cpp:
(WebCore::RenderLayerCompositor::RenderLayerCompositor):
(WebCore::RenderLayerCompositor::setRootExtendedBackgroundColor):
* rendering/RenderLayerCompositor.h:
Source/WebKit2:
Reviewed by Simon Fraser and Brent Fulgham.
New method on WKWebView and WKView will return the page’s extended background
color.
* UIProcess/API/Cocoa/WKViewPrivate.h:
* UIProcess/API/Cocoa/WKWebView.mm:
(-[WKWebView pageExtendedBackgroundColor]):
* UIProcess/API/Cocoa/WKWebViewPrivate.h:
* UIProcess/API/ios/WKViewIOS.mm:
(-[WKView pageExtendedBackgroundColor]):
The color is stored in the WebPageProxy, and the ChromeClient sends a message to
the WebPageProxy with the new color whenever it changes.
* UIProcess/WebPageProxy.cpp:
(WebKit::WebPageProxy::pageExtendedBackgroundColorDidChange):
* UIProcess/WebPageProxy.h:
