Class AccessibleRole

Table des matières

  • public class AccessibleRole
extends AccessibleBundle

    Class AccessibleRole determines the role of a component. The role of a component describes its generic function. (E.G., "push button," "table," or "list.")

    The 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.

    • Constructor Detail

      • AccessibleRole

        protected AccessibleRole(String key)
        Creates a new AccessibleRole using the given locale independent key. This should not be a public method. Instead, it is used to create the constants in this file to make it a strongly typed enumeration. Subclasses of this class should enforce similar policy.

        The key String should be a locale independent key for the role. It is not intended to be used as the actual String to display to the user. To get the localized string, use toDisplayString.

        Parameters:
        key - the locale independent name of the role.
        See Also:
        AccessibleBundle.toDisplayString(java.lang.String, java.util.Locale)
