The RadioButtonAccImpl class, also called the RadioButton Accessibility Implementation class, is used to make a RadioButton component accessible. This class enables communication between a RadioButton component and a screen reader. Screen readers are used to translate screen content into synthesized speech or braille for visually impaired users.

The RadioButtonAccImpl class supports system roles, object-based events, and states.

A RadioButton reports the role ROLE_SYSTEM_RADIOBUTTON (0x2D) to a screen reader.

A RadioButton reports the following states to a screen reader:

• STATE_SYSTEM_NORMAL (0x00000000)
• STATE_SYSTEM_UNAVAILABLE (0x00000001)
• STATE_SYSTEM_FOCUSED (0x00000004)
• STATE_SYSTEM_PRESSED (0x00000008)
• STATE_SYSTEM_CHECKED (0x00000010)
• STATE_SYSTEM_FOCUSABLE (0x00100000)

A RadioButton dispatches the following events to a screen reader:
