Provided Methods

unsafe fn accessibilityElementWithToken( &self, token: &NSAccessibilityLoadingToken, ) -> Option<Retained<ProtocolObject<dyn NSAccessibilityElementProtocol>>>

where Self: Sized + Message,

Available on crate feature NSAccessibilityConstants only.

Loads the target element with the given load token.

Returns: An element that will be messaged for other accessibility properties. Assistive technologies may try to set accessibility focus on the returned element.

Safety

token should be of the correct type.

unsafe fn accessibilityRangeInTargetElementWithToken( &self, token: &NSAccessibilityLoadingToken, ) -> NSRange

where Self: Sized + Message,

Available on crate feature NSAccessibilityConstants only.

For text-based elements returned from accessibilityElementWithToken, such as an NSTextView, the range specifies an area of interest. Assistive technologies will try to bring focus to the specified text range.

Either do not implement this method or return NSNotFound for the location if there is no range of interest for a given load token.

Safety

token should be of the correct type.
