Making Custom Components Accessible

Adding accessibility support to your custom widget will assure its cooperation with the accessibility infrastructure. These are the general steps that are required:

• assess a custom widget according to the applicable human interface guidelines

• determine which accessible role a custom widget should provide, according to the widget’s feature set and function

• update the appropriate accessible properties when the widget’s content change

• update the appropriate accessible states when the widget’s state changes

• update the appropriate accessible relations between the custom widget and its children
