Warning: serialized objects of this class will not be compatible with
future swing releases. The current serialization support is appropriate
for short term storage or RMI between Swing1.0 applications. It will
not be possible to load serialized Swing1.0 objects with future releases
of Swing. The JDK1.2 release of Swing will be the compatibility
baseline for the serialized form of Swing objects.

JTextComponent.AccessibleJTextComponent
public JTextComponent.AccessibleJTextComponent(JTextComponent this$0)
- Construct an AccessibleJTextComponent
caretUpdate
public void caretUpdate(CaretEvent e)
- Handle caret updates (fire appropriate property change event)
- Implements:
- caretUpdate in interface CaretListener
- Parameters:
e
- the CaretEvent
insertUpdate
public void insertUpdate(DocumentEvent e)
- Handle document insert (fire appropriate property change event)
- Implements:
- insertUpdate in interface DocumentListener
- Parameters:
e
- the DocumentEvent
removeUpdate
public void removeUpdate(DocumentEvent e)
- Handle document remove (fire appropriate property change event)
- Implements:
- removeUpdate in interface DocumentListener
- Parameters:
e
- the DocumentEvent
changedUpdate
public void changedUpdate(DocumentEvent e)
- Handle document remove (fire appropriate property change event)
- Implements:
- changedUpdate in interface DocumentListener
- Parameters:
e
- the DocumentEvent
getAccessibleStateSet
public AccessibleStateSet getAccessibleStateSet()
- Get the state set of the JTextComponent.
The AccessibleStateSet of an object is composed of a set of
unique AccessibleState's. A change in the AccessibleStateSet
of an object will cause a PropertyChangeEvent to
be fired for the ACCESSIBLE_STATE_PROPERTY property.
- Returns:
- an instance of AccessibleStateSet containing the
current state set of the object
- Overrides:
- getAccessibleStateSet in class JComponent.AccessibleJComponent
- See Also:
- AccessibleStateSet, AccessibleState, addPropertyChangeListener
getAccessibleRole
public AccessibleRole getAccessibleRole()
- Gets the role of this object.
- Returns:
- an instance of AccessibleRole describing the role of the
object
- Overrides:
- getAccessibleRole in class JComponent.AccessibleJComponent
- See Also:
- AccessibleRole
getAccessibleText
public AccessibleText getAccessibleText()
- Gets the AccessibleText interface associated with this object
- Returns:
- an instance of AccessibleText
- Overrides:
- getAccessibleText in class AccessibleContext
getIndexAtPoint
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.
- Implements:
- getIndexAtPoint in interface AccessibleText
- Parameters:
p
- the Point in local coordinates
- Returns:
- the zero-based index of the character under Point p.
getCharacterBounds
public Rectangle getCharacterBounds(int i)
- Determine 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.
- Implements:
- getCharacterBounds in interface AccessibleText
- Parameters:
i
- the index into the String
- Returns:
- the screen coordinates of the character's the bounding box
getCharCount
public int getCharCount()
- Return the number of characters (valid indicies)
- Implements:
- getCharCount in interface AccessibleText
- Returns:
- the number of characters
getCaretPosition
public int getCaretPosition()
- Return 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).
- Implements:
- getCaretPosition in interface AccessibleText
- Returns:
- the zero-based offset of the caret.
getCharacterAttribute
public AttributeSet getCharacterAttribute(int i)
- Return the AttributeSet for a given character (at a given index)
- Implements:
- getCharacterAttribute in interface AccessibleText
- Parameters:
i
- the zero-based index into the text
- Returns:
- the AttributeSet of the character
getSelectionStart
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.
- Implements:
- getSelectionStart in interface AccessibleText
- Returns:
- the index into the text of the start of the selection
getSelectionEnd
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.
- Implements:
- getSelectionEnd in interface AccessibleText
- Returns:
- the index into teh text of the end of the selection
getSelectedText
public String getSelectedText()
- Returns the portion of the text that is selected.
- Implements:
- getSelectedText in interface AccessibleText
- Returns:
- the portion of the text that is selected
getAtIndex
public String getAtIndex(int part,
int index)
- Return the String at a given index.
- Implements:
- getAtIndex in interface AccessibleText
- Parameters:
part
- the CHARACTER, WORD, or SENTENCE to retrieve
index
- an index within the text
- Returns:
- the letter, word, or sentence
getAfterIndex
public String getAfterIndex(int part,
int index)
- Return the String after a given index.
- Implements:
- getAfterIndex in interface AccessibleText
- Parameters:
part
- the CHARACTER, WORD, or SENTENCE to retrieve
index
- an index within the text
- Returns:
- the letter, word, or sentence
getBeforeIndex
public String getBeforeIndex(int part,
int index)
- Return the String before a given index.
- Implements:
- getBeforeIndex in interface AccessibleText
- Parameters:
part
- the CHARACTER, WORD, or SENTENCE to retrieve
index
- an index within the text
