AXBraille Map Renderer

Overview

You update the braille display in one of these ways:

• accessibilityBrailleMapRenderRegion: to specify an area of the UI to render to the braille display. With this approach, VoiceOver handles the process of converting the data to a braille map by rendering the image of the screen in that region and updating the braille display automatically.
• accessibilityBrailleMapRenderer: to update the braille map manually. With this approach, you get more detailed control over what to display, but you must modify the braille map yourself.

Topics (Grouped)

Rendering a specific region

• accessibilityBrailleMapRenderRegion:CGRect — var; A region of the UI that the system converts into a braille map and displays on the braille display.

Updating the braille map manually

• accessibilityBrailleMapRenderer: (AXBrailleMap) ->Void — var; A handler that the system calls to let you update the Braille map.

Inherits From

• NSObjectProtocol

Braille maps

• AXBrailleMap — class; A representation of a two-dimensional braille display.
