## Class AccessibleState

- java.lang.Object
- - javax.accessibility.AccessibleBundle
  - - javax.accessibility.AccessibleState

-     public class AccessibleState
      extends AccessibleBundle

  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 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.

    - #### ACTIVE

          public static final AccessibleState ACTIVE

      Indicates a window is currently the active window. This includes windows, dialogs, frames, etc. In addition, this state is used to indicate the currently active child of a component such as a list, table, or tree. For example, the active child of a list is the child that is drawn with a rectangle around it.

    - #### EDITABLE

          public static final AccessibleState EDITABLE

      Indicates the user can change the contents of this object. This is usually used primarily for objects that allow the user to enter text. Other objects, such as scroll bars and sliders, are automatically editable if they are enabled.
      See Also:
        `ENABLED`

    - #### EXPANDABLE

          public static final AccessibleState EXPANDABLE

      Indicates this object allows progressive disclosure of its children. This is usually used with hierarchical objects such as trees and is often paired with the EXPANDED or COLLAPSED states.
      See Also:
        `EXPANDED`, `COLLAPSED`, `AccessibleRole.TREE`

    - #### COLLAPSED

          public static final AccessibleState COLLAPSED

      Indicates this object is collapsed. This is usually paired with the EXPANDABLE state and is used on objects that provide progressive disclosure such as trees.
      See Also:
        `EXPANDABLE`, `EXPANDED`, `AccessibleRole.TREE`

    - #### EXPANDED

          public static final AccessibleState EXPANDED

        `EXPANDABLE`, `COLLAPSED`, `AccessibleRole.TREE`

    - #### ENABLED

          public static final AccessibleState ENABLED

      Indicates this object is enabled. The absence of this state from an object's state set indicates this object is not enabled. An object that is not enabled cannot be manipulated by the user. In a graphical display, it is usually grayed out.

    - #### FOCUSABLE

          public static final AccessibleState FOCUSABLE

      Indicates this object can accept keyboard focus, which means all events resulting from typing on the keyboard will normally be passed to it when it has focus.
      See Also:
        `FOCUSED`

    - #### FOCUSED

          public static final AccessibleState FOCUSED

      Indicates this object currently has the keyboard focus.
      See Also:
        `FOCUSABLE`

    - #### ICONIFIED

          public static final AccessibleState ICONIFIED

      Indicates this object is minimized and is represented only by an icon. This is usually only associated with frames and internal frames.

    - #### OPAQUE

          public static final AccessibleState OPAQUE

      Indicates this object paints every pixel within its rectangular region. A non-opaque component paints only some of its pixels, allowing the pixels underneath it to "show through". A component that does not fully paint its pixels therefore provides a degree of transparency.
      See Also:
        `Accessible.getAccessibleContext()`, `AccessibleContext.getAccessibleComponent()`, `AccessibleComponent.getBounds()`

    - #### RESIZABLE

          public static final AccessibleState RESIZABLE

      Indicates the size of this object is not fixed.
      See Also:

    - #### SELECTED

          public static final AccessibleState SELECTED

      Indicates this object is the child of an object that allows its children to be selected, and that this child is one of those children that has been selected.
      See Also:
        `SELECTABLE`, `Accessible.getAccessibleContext()`, `AccessibleContext.getAccessibleSelection()`, `AccessibleSelection`

    - #### SHOWING

          public static final AccessibleState SHOWING

      Indicates this object, the object's parent, the object's parent's parent, and so on, are all visible. Note that this does not necessarily mean the object is painted on the screen. It might be occluded by some other showing object.
      See Also:
        `VISIBLE`

    - #### VISIBLE

          public static final AccessibleState VISIBLE

      Indicates this object is visible. Note: this means that the object intends to be visible; however, it may not in fact be showing on the screen because one of the objects that this object is contained by is not visible.
      See Also:
        `SHOWING`

    - #### VERTICAL

          public static final AccessibleState VERTICAL

      Indicates the orientation of this object is vertical. This is usually associated with objects such as scrollbars, sliders, and progress bars.

    - #### HORIZONTAL

          public static final AccessibleState HORIZONTAL

      Indicates the orientation of this object is horizontal. This is usually associated with objects such as scrollbars, sliders, and progress bars.
      See Also:
        `HORIZONTAL`, `AccessibleRole.SCROLL_BAR`, `AccessibleRole.SLIDER`, `AccessibleRole.PROGRESS_BAR`

    - #### SINGLE_LINE

          public static final AccessibleState SINGLE_LINE

      Indicates this (text) object can contain only a single line of text

    - #### MULTI_LINE

          public static final AccessibleState MULTI_LINE

      Indicates this (text) object can contain multiple lines of text

    - #### TRANSIENT

          public static final AccessibleState TRANSIENT

      Indicates this object is transient. An assistive technology should not add a PropertyChange listener to an object with transient state, as that object will never generate any events. Transient objects are typically created to answer Java Accessibility method queries, but otherwise do not remain linked to the underlying object (for example, those objects underneath lists, tables, and trees in Swing, where only one actual UI Component does shared rendering duty for all of the data objects underneath the actual list/table/tree elements).
      Since:
        1.5

    - #### MANAGES_DESCENDANTS

          public static final AccessibleState MANAGES_DESCENDANTS

      Indicates this object is responsible for managing its subcomponents. This is typically used for trees and tables that have a large number of subcomponents and where the objects are created only when needed and otherwise remain virtual. The application should not manage the subcomponents directly.
      Since:
        1.5

    - #### INDETERMINATE

          public static final AccessibleState INDETERMINATE

      Indicates that the object state is indeterminate. An example is selected text that is partially bold and partially not bold. In this case the attributes associated with the selected text are indeterminate.
      Since:
        1.5

    - #### TRUNCATED

          public static final AccessibleState TRUNCATED

      A state indicating that text is truncated by a bounding rectangle and that some of the text is not displayed on the screen. An example is text in a spreadsheet cell that is truncated by the bounds of the cell.
      Since:
        1.5

  - ### Constructor Detail

    - #### AccessibleState

          protected AccessibleState(String key)

      Creates a new AccessibleState 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 state. 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 state.
      See Also:
        `AccessibleBundle.toDisplayString(java.lang.String, java.util.Locale)`
