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

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

A LabelButton reports the role ROLE_SYSTEM_PUSHBUTTON (0x2B) to a screen reader.

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