AccessibleRole.PUSH_BUTTON
. The roles in AccessibleRole
are provided so component developers can pick from a set of predefined roles. This enables assistive technologies to provide a consistent interface to various tweaked subclasses of components (e.g., use AccessibleRole.PUSH_BUTTON
for all components that act like a push button) as well as distinguish between subclasses that behave differently (e.g., AccessibleRole.CHECK_BOX
for check boxes and AccessibleRole.RADIO_BUTTON
for radio buttons). Note that the AccessibleRole
class is also extensible, so custom component developers can define their own AccessibleRole
's if the set of predefined roles is inadequate.
