Bug 37625 – [Chromium] Add some notifications and an accessor to WebKit API

• Component: WebKit API
• Status: RESOLVED FIXED

[Jens Alfke]

For some work I'm doing on Chromium* I need to add a few methods to the WebKit API to expose WebCore functionality:

1. WebElement::isVisible — tells whether a DOM element is visible (defined as 'has a layout with a non-empty bounding box').
2. WebFrame::didFirstLayout and WebFrame::didFirstVisuallyNonEmptyLayout — these are equivalent to the FrameLoaderClient methods of the same names.

I actually linked to the wrong Chromium bug, below. The correct one is
"Password manager heuristics fail for sites that keep the login form around after signin"

Patch

WebKit/chromium/src/WebElement.cpp:76
 +  // Note: This method only works properly after layout has occurred.
This comment would be helpful in the public header file.

WebKit/chromium/src/WebElement.cpp:79
 +      // (Copied from HTMLAnchorElement::isKeyboardFocusable)
It seems rather unfortunate to duplicate this code.  Can it be shared somehow?

WebKit/chromium/public/WebFrameClient.h:198
 +      // The frame's document finished the initial layout of a page.
This would probably be better in the "Geometry notifications" section instead of the "Navigational notifications" section.

WebKit/chromium/public/WebElement.h:60
 +          WEBKIT_API bool isVisible() const;
how about naming this method hasNonEmptyBoundingBox?  that way the method name is self documenting and more accurate.  if a consumer wants to use that to test visibility, then the fact that it is not a 100% guarantee is an issue for the user instead of a problem with the implementation of this method.

OK, I have moved the hasNonEmptyBoundingBox method up to Node, and made the other changes you suggested.

The Chromium patch (fix for 28911) that's depending on this is now approved, and waiting on this patch to get checked in and downstreamed to Chromium first.
