UI Automation also offers a simple text object model with the Text control pattern, which supports embedding objects in a Document object. Value ( Value control pattern) NOTE: The RangeValue and Value control patterns can coexist with UI Automation when both valuetext and valuenow are specified. IAccessible::get_accValue NOTE: When both the valuenow and valuetext ARIA properties are set, accValue holds the data from the ARIA valuetext property. N/a (child count in automation element tree structure) IsSelected ( SelectionItem control pattern) N/a (represented in automation element tree structure) N/a (represented in the accessible object tree structure or by childId) N/a (should be reflected in the automation element tree) N/a (should be reflected in the accessible object tree) N/a (represented by automation element tree structure)ĬanSelectMultiple ( Selection control pattern) STATE_SYSTEM_COLLAPSED or STATE_SYSTEM_EXPANDED (accState)ĮxpandCollapseState ( ExpandCollapse control pattern) HasKeyboardFocus (a property of the child element that is designated to receive the focus) Microsoft Active Accessibility Properties The provider code can add verification to validate the original ARIA properties in the Document Object Model, but it is not required. A backslash (\) is used as an escape when these delimiter characters, or a backslash, appear in the values. The ARIA owns property should be also reflected in the accessibility object model when it is specified.ĪriaProperties is a string property that has a collection of name/value pairs whose delimiters are the equal sign (=) and the semicolon ( ), for example, "checked=true disabled=false". For example, the ARIA activedescendent property is expected to be represented as the element with focus in the accessibility object model. The exceptions are ARIA properties that take object references (for example, the describedby ARIA property), and ARIA properties that are supported by the accessibility object model. Most of the ARIA states and properties are supported by the UI Automation AriaProperties property. W3C ARIA states and properties map to various Microsoft Active Accessibility and UI Automation properties and functions. W3C ARIA States and Properties Mapped to Microsoft Active Accessibility and UI Automation User agents may also offer secondary roles in the AriaRole property by using space as a separator, as defined in the ARIA W3C standard. When a localized string is not specified, the system will supply the default LocalizedControlType string. User agents can offer a localized description of the W3C ARIA role with the UI Automation LocalizedControlType property however, that is optional. With UI Automation, the original W3C ARIA role may also be supported by the AriaRole property. W3C ARIA roles can map to Microsoft Active Accessibility roles or UI Automation control types.
