Suppressing Spawning of Viewport Caused by the HTML4 Attribute target="new"

WARNING: EXPLANATORY TEXT NOT YET STABLE OR COMPLETE!

What Is Being Tested?

This document is part of a suite of pages designed to test the implementation of the W3C's User Agent Accessibility Guidelines (UAAG). In particular, this page is designed to test implementation of checkpoints 5.1, 5.2, 5.3 and 5.4:

5.1 No automatic content focus change. Allow configuration so that if a viewport opens without explicit user request, its content focus does not automatically become the current focus. Configuration is not required if the content focus can only ever be moved by explicit user request. [Priority 2] Both content and user agent.

Techniques for checkpoint 5.1

5.2 Keep viewport on top. For graphical user interfaces, allow configuration so that the viewport with the current focus remains "on top" of all other viewports with which it overlaps. [Priority 2] Both content and user agent.

Techniques for checkpoint 5.2

5.3 Manual viewport open only. Allow configuration so that viewports only open on explicit user request. In this configuration, instead of opening a viewport automatically, alert the user and allow the user to open it on demand (e.g., by following a link or confirming a prompt). Allow the user to close viewports. If a viewport (e.g., a frame set) contains other viewports, these requirements only apply to the outermost container viewport. [Priority 2] Both content and user agent.

Note: User creation of a new viewport (e.g., empty or with a new resource loaded) through the user agent's user interface constitutes an explicit user request. See also checkpoint 5.1 (for control over changes of focus when a viewport opens) and checkpoint 6.5 (for programmatic alert of changes to the user interface).

Techniques for checkpoint 5.3

5.4 Selection and focus in viewport. Ensure that when a viewport's selection or content focus changes, it is at least partially in the viewport after the change. [Priority 2] Both content and user agent.

Note: For example, if users navigating links move to a portion of the document outside a graphical viewport, the viewport should scroll to include the new location of the focus. Or, for users of audio viewports, allow configuration to render the selection or focus immediately after the change.

Techniques for checkpoint 5.4

How to Provide Feedback

Please send comments and observations about this test page to <w3c-wai-ua@w3.org>. Your comments will be archived in the User Agent mailing list's public hypertext archive. Please make your observations as specific and detailed as possible. Be sure to include the following information when you report your observations to the User Agent Accessibility Guidelines Working Group:

1. operating system (including version/revision number)
2. assistive technology, if any (please include version number)
3. user agent name and version (e.g. MSIE, version 5.00.2920.0000 update versions ;q254902)
4. any special settings (i.e. any changes you or your adaptive equipment made to your user agent's default configuration)
5. a description of what happened when you attempted to follow the links to the WAI Guidelines, in particular:
   • did you receive any indication, other than this page's explanatory text, that the links to the Guidelines documents would/could open in a new viewport?
   • did the selected document open in a new viewport?
   • were you prompted to confirm the opening of a new viewport? how did you respond? what happened as a result of your response? please be as specific as possible in detailing the method you used to respond to any prompt, including specific keystrokes;
   • if you were prompted, were you able to review the contents of the prompt?
   • if the document opened in a new viewport, did the current viewport (this page) remain "on top", or was focus reestablished in the new viewport--that is, on the guidelines document you selected? if this document remained "on top", were you notified by the user agent that it had opened a new viewport?
   • if your user agent allows you to view more than one viewport at a time, did this page retain focus when the selected Guidelines document opened in a new viewport? if the viewports overlap, did this document remain "on top" of any/all of the viewports which it overlaps?
   • are you aware of any user agent settings which allow you to specify how and when to open a linked resource in a new viewport? how much control over the opening, rendering, and placement of new viewports does your user agent offer?
