public interface: AccessibleText [javadoc |
source]
All Known Implementing Classes:
JEditorPaneAccessibleHypertextSupport, AccessibleProgressMonitor, AccessibleEditableText, AccessibleJTextComponent, AccessibleJSpinner, AccessibleJLabel, AccessibleAWTTextComponent, AccessibleAbstractButton, TextAccessibleContext, AccessibleHypertext
The AccessibleText interface should be implemented by all
classes that present textual information on the display. This interface
provides the standard mechanism for an assistive technology to access
that text via its content, attributes, and spatial location.
Applications can determine if an object supports the AccessibleText
interface by first obtaining its AccessibleContext (see Accessible )
and then calling the AccessibleContext#getAccessibleText method of
AccessibleContext. If the return value is not null, the object supports this
interface.
Field Summary |
---|
public static final int | CHARACTER | Constant used to indicate that the part of the text that should be
retrieved is a character. |
public static final int | WORD | Constant used to indicate that the part of the text that should be
retrieved is a word. |
public static final int | SENTENCE | Constant used to indicate that the part of the text that should be
retrieved is a sentence.
A sentence is a string of words which expresses an assertion,
a question, a command, a wish, an exclamation, or the performance
of an action. In English locales, the string usually begins with
a capital letter and concludes with appropriate end punctuation;
such as a period, question or exclamation mark. Other locales may
use different capitalization and/or punctuation. |

Method from javax.accessibility.AccessibleText Detail: |
public String getAfterIndex(int part,
int index)
Returns the String after a given index. |
public String getAtIndex(int part,
int index)
Returns the String at a given index. |
public String getBeforeIndex(int part,
int index)
Returns the String before a given index. |
public int getCaretPosition()
Returns the zero-based offset of the caret.
Note: That to the right of the caret will have the same index
value as the offset (the caret is between two characters). |
public int getCharCount()
Returns the number of characters (valid indicies) |
public AttributeSet getCharacterAttribute(int i)
Returns the AttributeSet for a given character at a given index |
public Rectangle getCharacterBounds(int i)
Determines the bounding box of the character at the given
index into the string. The bounds are returned in local
coordinates. If the index is invalid an empty rectangle is returned. |
public int getIndexAtPoint(Point p)
Given a point in local coordinates, return the zero-based index
of the character under that Point. If the point is invalid,
this method returns -1. |
public String getSelectedText()
Returns the portion of the text that is selected. |
public int getSelectionEnd()
Returns the end offset within the selected text.
If there is no selection, but there is
a caret, the start and end offsets will be the same. |
public int getSelectionStart()
Returns the start offset within the selected text.
If there is no selection, but there is
a caret, the start and end offsets will be the same. |
