Bug 106756 – AX: Need to implement ColorWellRole

• Component: Accessibility
• Status: RESOLVED FIXED

[Dominic Mazzoni]

Chromium implements <input type="color"> using a native Mac color well, so it's important to support this role.

the AXValue for a color well should return something like

AXValue	rgb 0.76448 1 0.280308 1, so VO can speak the color

> Source/WebCore/accessibility/AccessibilityRenderObject.cpp:2466
> +        const AtomicString& type = input->getAttribute(typeAttr);

What case will this not be handled by the same code in AXNodeObject?

OK. I implemented the Mac version but the code won't be used until Safari has color well support. I implemented something similar in Chromium DRT.

Right now, AccessibilityRenderObject::determineAccessibilityRole doesn't call the inherited method. We need to refactor it some more to remove more duplication.

Is there a need to duplicate this logic in AXNodeObject currently then?

I think there are now two relatively obscure places in the code where AXNodeObject is used without AXRenderObject:

1. In canvas fallback content
2. In a subtree with display:none but aria-hidden=false

These are admittedly rare, but I still think it's right to implement this code in AXNodeObject and try to refactor it over time to put most of the logic there and use AXRenderObject only where the information we get from the render tree differs.
