Event Handlers

Rich: starting call with event handlers discussion

Rich: checked with becky; keyboard handlers are put on Dojo containers not child elements; mouse handlers on the children however

Rich: tree, tablist, menubar, menu, button, checkbox, listbox, list, etc. - do not test for keyboard handlers

Jon: However, need onfocus and onblur handlers on children.

Jon: Ask Becky what they do for Dojo regarding handlers on child elements.

Rich: Dont't events bubble up to the container?

Rich: Becky says any element with keyboard support has a handler on the container.

Jon: Managing styling from the parent container is sometimes difficult.

Jon: Opera and Safari have built in visible focus. However FF and IE doesn't. Managing focus on children is sometimes difficult from parent container.

Rich/Jon: A manual check for keyboard focus should be done when elements have keyboard handlers like onmousedown, onmouseup, onfocus, onblur.

Rich: Elements like buttons are not containers but a keyboard handler is necessary.

Jon: If checking keyboard support, check for focus also.

Jon: What's the trigger for checking for role?

Rich/jon: Trigger would be: Element must have a role if not a form or anchor and element has an event handler.

Incorrect Role Values

Jon: incorrect role values should be flagged (e.g.,menuitem not in a menu, treeitem not in a tree, etc.)

Rich: A container role (e.g., tree, grid, menu, etc.) must have at lease one child with an clickable role as defined by aria. Otherwise generate a violation.

Coding Patterns

Rich: Moving on to Coding Patterns

Jon Can we assume that for example if one item in a tree has a treeitem role, all child items without a specified role are treeitems. Or, do we want to warn people when child element roles are missing.

Rich: We should stick to best practices. Yes we should flag a violation.

David: Maybe we should flag a potential violation for this instead of violation.

Preety: Question about tree and treeitem example (i.e., if missing treeitem roles on child elements should missing roles be assumed treeitems?).

Rich: yes


Rich: Moving on to -> Elements of role values must have tabindex defined with the correct value.

Rich Unless the container has an activedecendent.

Jon: Does tabindex need to be set to -1 for child elements using activedescendent?

Rich: Not necessarily.

Other Rules

Rich: Moving on to Other Rules

Jon: Why is frame title used? Is it needed?

Rich: If looking to be WCAG 2.0 compliant applications need title.

David Agree, need title to be WCAG 2.0 compliant.

Jon: Okay let's rephrase. If frame doesn't have a landmark, a title is needed.

Rich: Rewording frame title rule.

Jon: If a frame is marked presentational it doesn't need a title.

Team: no

Different chair for next two weeks

Rich: traveling next 2 weeks

Jon: chair next 2 weeks
