This information needs to be processed by web browsers and then conveyed to assistive technologies, such as screen readers. For instance, web content needs to include text alternatives for images. Use UI Browser to test the target while you write GUI Scripting scripts or while you add accessibility features to applications you are developing, and you can be confident they will work as expected.Īn alternative to futzing around with OS X’s Accessibility Inspector and AppleScript’s UI elements (a frustrating process, as the information provided by Accessibility Inspector doesn’t always match AppleScript’s understanding of the elements on your screen).These components inter-relate and support each other. Then use UI Browser to perform actions on the selected UI element, get and set its attributes, send keystrokes to the target application, and observe notifications when any of the target’s UI elements change.
