AccessibleTextpublic interface AccessibleText 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 {@link Accessible})
and then calling the {@link AccessibleContext#getAccessibleText} method of
AccessibleContext. If the return value is not null, the object supports this
interface. |
Fields Summary |
---|
public static final int | CHARACTERConstant used to indicate that the part of the text that should be
retrieved is a character. | public static final int | WORDConstant used to indicate that the part of the text that should be
retrieved is a word. | public static final int | SENTENCEConstant 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. |
Methods Summary |
---|
public java.lang.String | getAfterIndex(int part, int index)Returns the String after a given index.
| public java.lang.String | getAtIndex(int part, int index)Returns the String at a given index.
| public java.lang.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 javax.swing.text.AttributeSet | getCharacterAttribute(int i)Returns the AttributeSet for a given character at a given index
| public java.awt.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(java.awt.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 java.lang.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.
