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 Summary |
---|
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.Also see:
- AccessibleRole#WINDOW
- AccessibleRole#FRAME
- AccessibleRole#DIALOG
|
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.Also see:
- AccessibleRole#PUSH_BUTTON
|
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.Also see:
- AccessibleRole#PUSH_BUTTON
|
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.Also see:
- AccessibleRole#PROGRESS_BAR
- AccessibleRole#SCROLL_BAR
- AccessibleRole#SLIDER
|
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.Also see:
- AccessibleRole#TOGGLE_BUTTON
- AccessibleRole#RADIO_BUTTON
- AccessibleRole#CHECK_BOX
|
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. |
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. |
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. |
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. |
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. |
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. |
public static final AccessibleState | FOCUSED | Indicates this object currently has the keyboard focus. |
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.Also see:
- AccessibleRole#FRAME
- AccessibleRole#INTERNAL_FRAME
|
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.Also see:
- AccessibleRole#DIALOG
|
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.Also see:
- Accessible#getAccessibleContext
- AccessibleContext#getAccessibleComponent
- AccessibleComponent#getBounds
|
public static final AccessibleState | RESIZABLE | Indicates the size of this object is not fixed.Also see:
- Accessible#getAccessibleContext
- AccessibleContext#getAccessibleComponent
- AccessibleComponent#getSize
- AccessibleComponent#setSize
|
public static final AccessibleState | MULTISELECTABLE | Indicates this object allows more than one of its children to
be selected at the same time.Also see:
- Accessible#getAccessibleContext
- AccessibleContext#getAccessibleSelection
- AccessibleSelection
|
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. |
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. |
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. |
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. |
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.Also see:
- VERTICAL
- AccessibleRole#SCROLL_BAR
- AccessibleRole#SLIDER
- AccessibleRole#PROGRESS_BAR
|
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.Also see:
- HORIZONTAL
- AccessibleRole#SCROLL_BAR
- AccessibleRole#SLIDER
- AccessibleRole#PROGRESS_BAR
|
public static final AccessibleState | SINGLE_LINE | Indicates this (text) object can contain only a single line of text |
public static final AccessibleState | MULTI_LINE | Indicates this (text) object can contain multiple lines of text |
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). |
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. |
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. |
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. |
Constructor: |
protected AccessibleState(String key) {
this.key = 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.
