Class AccessibleState
describes a component's particular state. The actual state of the component is defined as an AccessibleStateSet
, which is a composed set of AccessibleStates
. The AccessibleBundle.toDisplayString()
method allows you to obtain the localized string for a locale independent key from a predefined ResourceBundle
for the keys defined in this class.
The constants in this class present a strongly typed enumeration of common
object roles. A public constructor for this class has been purposely omitted
and applications should use one of the constants from this class. If the
constants in this class are not sufficient to describe the role of an object,
a subclass should be generated from this class and it should provide
constants in a similar manner.
