992703 - User Interface Event Types and their inheritance

Status: RESOLVED INACTIVE

(Core :: DOM: Events, defect, P5)

Description

[Arkadiusz Michalski (Spirit)]

User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:28.0) Gecko/20100101 Firefox/28.0 (Beta/Release)
Build ID: 20140314220517

Steps to reproduce:

In D3E we have defined  User Interface Event Types (https://dvcs.w3.org/hg/dom3events/raw-file/tip/html/DOM3-Events.html#h4_events-uievents), but they can inherit from different interfaces:

- load, unload, abort, error, select (UIEvent if generated from a user interface, Event otherwise.) 
- resize, scroll (UIEvent)

When this event inherit from UIEvent we have access to UIEvent.view and this may be potentially useful.

I don't see that eny spec. define exactly what it means "UIEvent if generated from a user interface". Maybe HTML5 should describe this (https://www.w3.org/Bugs/Public/show_bug.cgi?id=25279). Without this all browsers work differently:

- Chrome always use Event
- Firefox use UIEvent only for scroll event.  << according D3E it should also be resize
- IE use UIEvent for select, resize and scroll.

None of these implementations are compatible with the specification, but specification in this case is not precise. I wrote this bug, maybe in the future the situation became more crystallizes or anyone interested in the topic and write to the appropriate people.

Move all DOM bugs that haven’t been updated in more than 3 years and has no one currently assigned to P5.

Olli, is this still valid? Thanks.

This isn't particularly useful anymore. If some event types aren't using the right interface, there should be separate bugs for those cases.
