366450 - implement accessible delegate object

Status: RESOLVED WONTFIX

(Core :: Disability Access APIs, defect)

Description

Attachment: to approve the idea

Idea is to redirect most of accessible properties/methods to another accessible object. For example,

<xf:input>
  <xbl:content>
    <html:select>
      <html:option/>
    </html:select>
  </xbl:content>
</xf:input>

I'd like to have one accessible object for xf:input instead if I will have two accessible object both for xf:input and for html:select. The idea is to redirect all calls from xf:input accessible object to html:select accessible object.

I think I like the idea, but what end user problem is it fixing?

I don't know right now :) I didn't test it yet. Though it provides "right" accessible objects. The one thing I don't like in this patch is copying all interfaces methods that involves if I change interface then I should change nsDelegateAccessible too.

Alexander, investigating the attached tcases. From what I see the tcase behaves correctly.

Interesting, but we don't need this.
