Bug 150379 – clang-700.0.59.5 finds additional deprecated declarations which breaks the build

• Component: WebKit Misc.
• Status: RESOLVED FIXED

[Gordon Sheridan]

There are two uses of -[NSWindow convertBaseToScreen:] in WebHTMLView.mm. This method has been deprecated since 10.7, but the code has been unchanged since 2005.

For iOS, we need to define -convertRectFromScreen: and -convertRectToScreen: in WAKWindow.h

This is ok as a build fix, but can you please add a FIXME saying that WAKWindow should instead implement -convertRectFromScreen:? After all, the whole point of WAKWindow is to avoid having to write code like this.

Ditto for -convertRectToScreen:.

> Source/WebKit/mac/WebView/WebHTMLView.mm:6119
> +    NSRect screenRect = { thePoint, NSZeroSize };

thePoint is in the window's coordinate space, so this should be called windowRect.

Also, a better name for thePoint would be screenPoint.

> Source/WebKit/mac/WebView/WebHTMLView.mm:6114
> +static NSPoint convertPointToScreen(NSWindow *window, NSPoint thePoint)

And a better name here for thePoint would be windowPoint.

WAKWindow versions of methods to convert an NSRect between window and screen coordinates.

This patch provides WAKWindow versions of the non-deprecated methods for converting an NSRect between window and screen coordinates, which replace the deprecated methods that operated on an NSPoint.

I like this a lot better, but I'm not sure the WAKWindow methods are correctly implemented.

> Source/WebCore/platform/ios/wak/WAKWindow.mm:163
> +- (NSRect)convertRectToScreen:(NSRect)windowRect
> +{
> +    windowRect.origin = [self convertBaseToScreen:windowRect.origin];
> +    return windowRect;
> +}

I'm not sure it's okay to convert a rect just by converting its origin. I would copy the implementation of -convertBaseToScreen:, but call -[CALayer convertRect:toLayer:] instead.

> Source/WebCore/platform/ios/wak/WAKWindow.mm:168
> +    screenRect.origin = [self convertScreenToBase:screenRect.origin];
> +    return screenRect;

Ditto for -[CALayer convertRect:fromLayer:].
