[iOS] WK2: Provide implementation for windowFrame

• Component: WebKit2
• Status: RESOLVED FIXED

[Brent Fulgham]

The WK2 layer for iOS was missing an implementation for windowRect, causing DOMWindow::outerWidth and DOMWindow::outerHeight to always return 0, 0.

And by windowRect I meant windowFrame.

Let's talk about it tomorrow.

After reading http://www.quirksmode.org/blog/archives/2012/03/windowouterwidt.html
it looks like we have an extra bug to fix on WebKit1... :(

I think you want to the bounds, not the frame.

We should have an extra step here:
-Try to get the UIWindow from the WebView. If there is a window, return that size.
-If there is not window, return the WebView bounds.

Sorry, that's my fault. When you said we need to convert the rect to user space, I thought you meant in the WebProcess to convert to ContentCoordinates.

This is not right. I think you can just return the incoming rect here on iOS.

if (UIWindow* window = m_uiDelegate.m_webView.window)
    ...

Missing period.
But I think you should remove the comment.
