[GTK] Expose HitTestResult::scrollbar() condition in API

• Component: WebKit2
• Status: RESOLVED FIXED

[Eduardo Lima Mitev]

Specific UX behaviors require discriminating hits over elements' scrollbars, specially the WebView's main scrollbars. For example, any application behavior implemented on middle button, could break scrolling if the hit occurs over any scrollbars in the page.

Adding dependency on bug 99591.

Patch looks great, thanks! Setting r- just because it doesn't include unit tests. You can modify WebKitWebView/mouse-target test to check it. Use a form control containing scrollbars, because main scrollbars won't work due to bug #99591.

I would use isScrollbar.

> Source/WebKit2/Shared/WebHitTestResult.h:87
> +            , isOverScrollbar(hitTestResult.scrollbar())

Ditto.

previous patch with unit test

This is the previous patch updated to include unit test, and to replace WebHitTestResult::isOverScrollbar by isScrollbar as suggested.

Thanks for reviewing

Please, move these below adding per function explanations instead. Sorry, that I didn't notice this in the previous patch.

The ChangeLog syntax in previous patch was still wrong.
