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.

Field Detail

### 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.

  See Also:
    `AccessibleRole.WINDOW`, `AccessibleRole.FRAME`, `AccessibleRole.DIALOG`

### PRESSED

    public static final AccessibleState PRESSED

  Indicates this object is currently pressed. This is usually associated with buttons and indicates the user has pressed a mouse button while the pointer was over the button and has not yet released the mouse button.

  See Also:
    `AccessibleRole.PUSH_BUTTON`

### ARMED

    public static final AccessibleState ARMED

  Indicates that the object is armed. This is usually used on buttons that have been pressed but not yet released, and the mouse pointer is still over the button.

  See Also:
    `AccessibleRole.PUSH_BUTTON`

### BUSY

    public static final AccessibleState BUSY

  Indicates the current object is busy. This is usually used on objects such as progress bars, sliders, or scroll bars to indicate they are in a state of transition.

  See Also:
    `AccessibleRole.PROGRESS_BAR`, `AccessibleRole.SCROLL_BAR`, `AccessibleRole.SLIDER`

### CHECKED

    public static final AccessibleState CHECKED

  Indicates this object is currently checked. This is usually used on objects such as toggle buttons, radio buttons, and check boxes.

  See Also:
    `AccessibleRole.TOGGLE_BUTTON`, `AccessibleRole.RADIO_BUTTON`, `AccessibleRole.CHECK_BOX`

### 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

  Indicates this object is expanded. This is usually paired with the EXPANDABLE state and is used on objects that provide progressive disclosure such as trees.

  See Also:
    `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.

  See Also:
    `AccessibleRole.FRAME`, `AccessibleRole.INTERNAL_FRAME`

### MODAL

    public static final AccessibleState MODAL

  Indicates something must be done with this object before the user can interact with an object in a different window. This is usually associated only with dialogs.

  See Also:
    `AccessibleRole.DIALOG`

### 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:
    `Accessible.getAccessibleContext()`, `AccessibleContext.getAccessibleComponent()`, `AccessibleComponent.getSize()`, `AccessibleComponent.setSize(java.awt.Dimension)`

### MULTISELECTABLE

    public static final AccessibleState MULTISELECTABLE

  Indicates this object allows more than one of its children to be selected at the same time.

  See Also:
    `Accessible.getAccessibleContext()`, `AccessibleContext.getAccessibleSelection()`, `AccessibleSelection`

### SELECTABLE

    public static final AccessibleState SELECTABLE

  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 can be selected.

  See Also:
    `SELECTED`, `Accessible.getAccessibleContext()`, `AccessibleContext.getAccessibleSelection()`, `AccessibleSelection`

### 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.

  See Also:
    `VERTICAL`, `AccessibleRole.SCROLL_BAR`, `AccessibleRole.SLIDER`, `AccessibleRole.PROGRESS_BAR`

### 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).

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.

Parameters:
  `key` - the locale independent name of the state.

  `AccessibleBundle.toDisplayString(java.lang.String, java.util.Locale)`
