Bug 113829 – [BlackBerry] Decouple layout viewport from visual viewport

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

[Arvid Nilsson]

Setting the visual viewport will force the layout viewport equal to the visual viewport. Decouple by allowing the user to specify a layout viewport (which could be the exact same value they pass for visual viewport, if that's their cup of tea).

Looks good to me in general, but patch doesn't seem to apply.

Comments should finish with a period.

recomputeVirtualViewportFromViewportArguments already checks whether viewport arguments have changed, so you could avoid checking it twice, by checking if the returned rectangle is empty.

> Source/WebKit/blackberry/Api/WebPage.h:144
> +    // Returns the size of the visual viewport

Ditto.

> Source/WebKit/blackberry/Api/WebPage.h:147
> +    // Sets the sizes of the visual viewport and the layout viewport

Ditto.

> Source/WebKit/blackberry/Api/WebPage.h:153
> +    // Returns the size of the layout viewport

Ditto.

This is a great idea, to avoid duplicating the ugly "static ViewportArguments defaultViewportArguments" line all over the place.

Thanks for the review, I found one more place where we can apply the idea and get rid of static ViewportArguments defaultViewportArguments;.
