All viewer components support ARIA (Accessible Rich Internet Applications) roles and attributes to improve integration with assistive technologies such as screen readers.
The top-level viewer element has role region
and aria-label
attribute set by default to the name of the viewer. You can control the label with the Container.LABEL
localization symbol.
Buttons have the role button
and descriptive text set with aria-label
attribute. The value of aria-label
attribute is populated from the value of the button’s localization symbol. When a button is disabled, aria-disabled
attribute is set accordingly.
The main view has role application
. A brief description of the main view is provided in aria-roledescription
, with the value defined by the ROLE_DESCRIPTION
localization symbol of the corresponding main view component. Navigation hints for keyboard users are provided using aria-describedby
, the text for the usage hint comes from the USAGE_HINT
localization symbol. If an asset has a label defined in the UserData field, the aria-label
attribute is set with the value of such label.
Components that display swatches have the role listbox
with aria-label
attribute set to the value of the LABEL
localization symbol of that component. Individual swatches have the role option
with aria-setsize
and aria-posinset
attributes to describe the swatch position in the set. If a swatch is selected, it gets the aria-selected
attribute set to true
.
Slider components have the role slider
with attributes aria-valuenow
, aria-valuemin
, and aria-valuemax
to describe the current slider position.
