Method Detail- 
textValueChangedpublic void textValueChanged(TextEvent textEvent) TextListener notification of a text value change.- Specified by:
- textValueChangedin interface- TextListener
- Parameters:
- textEvent- the event to be processed
 
 - 
getAccessibleStateSetpublic AccessibleStateSet getAccessibleStateSet() Gets the state set of the TextComponent. The AccessibleStateSet of an object is composed of a set of unique AccessibleStates. A change in the AccessibleStateSet of an object will cause a PropertyChangeEvent to be fired for the AccessibleContext.ACCESSIBLE_STATE_PROPERTY property.- Overrides:
- getAccessibleStateSetin class- Component.AccessibleAWTComponent
- Returns:
- an instance of AccessibleStateSet containing the current state set of the object
- See Also:
- AccessibleStateSet,- AccessibleState,- Component.AccessibleAWTComponent.addPropertyChangeListener(java.beans.PropertyChangeListener)
 
 - 
getAccessibleRolepublic AccessibleRole getAccessibleRole() Gets the role of this object.- Overrides:
- getAccessibleRolein class- Component.AccessibleAWTComponent
- Returns:
- an instance of AccessibleRole describing the role of the object (AccessibleRole.TEXT)
- See Also:
- AccessibleRole
 
 - 
getAccessibleTextpublic AccessibleText getAccessibleText() Get the AccessibleText associated with this object. In the implementation of the Java Accessibility API for this class, return this object, which is responsible for implementing the AccessibleText interface on behalf of itself.- Overrides:
- getAccessibleTextin class- AccessibleContext
- Returns:
- this object
- See Also:
- AccessibleText
 
 - 
getIndexAtPointpublic 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.- Specified by:
- getIndexAtPointin interface- AccessibleText
- Parameters:
- p- the Point in local coordinates
- Returns:
- the zero-based index of the character under Point p.
 
 - 
getCharacterBoundspublic 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 a null rectangle is returned.- Specified by:
- getCharacterBoundsin interface- AccessibleText
- Parameters:
- i- the index into the String >= 0
- Returns:
- the screen coordinates of the character's bounding box
 
 - 
getCharCountpublic int getCharCount() Returns the number of characters (valid indices)- Specified by:
- getCharCountin interface- AccessibleText
- Returns:
- the number of characters >= 0
 
 - 
getCaretPositionpublic int getCaretPosition() Returns the zero-based offset of the caret. Note: The character to the right of the caret will have the same index value as the offset (the caret is between two characters).- Specified by:
- getCaretPositionin interface- AccessibleText
- Returns:
- the zero-based offset of the caret.
 
 - 
getCharacterAttributepublic AttributeSet getCharacterAttribute(int i) Returns the AttributeSet for a given character (at a given index).- Specified by:
- getCharacterAttributein interface- AccessibleText
- Parameters:
- i- the zero-based index into the text
- Returns:
- the AttributeSet of the character
 
 - 
getSelectionStartpublic 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. Return 0 if the text is empty, or the caret position if no selection.- Specified by:
- getSelectionStartin interface- AccessibleText
- Returns:
- the index into the text of the start of the selection >= 0
 
 - 
getSelectionEndpublic 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. Return 0 if the text is empty, or the caret position if no selection.- Specified by:
- getSelectionEndin interface- AccessibleText
- Returns:
- the index into the text of the end of the selection >= 0
 
 - 
getSelectedTextpublic String getSelectedText() Returns the portion of the text that is selected.- Specified by:
- getSelectedTextin interface- AccessibleText
- Returns:
- the text, null if no selection
 
 - 
getAtIndexpublic String getAtIndex(int part, int index) Returns the String at a given index.- Specified by:
- getAtIndexin interface- AccessibleText
- Parameters:
- part- the AccessibleText.CHARACTER, AccessibleText.WORD, or AccessibleText.SENTENCE to retrieve
- index- an index within the text >= 0
- Returns:
- the letter, word, or sentence, null for an invalid index or part
 
 - 
getAfterIndexpublic String getAfterIndex(int part, int index) Returns the String after a given index.- Specified by:
- getAfterIndexin interface- AccessibleText
- Parameters:
- part- the AccessibleText.CHARACTER, AccessibleText.WORD, or AccessibleText.SENTENCE to retrieve
- index- an index within the text >= 0
- Returns:
- the letter, word, or sentence, null for an invalid index or part
 
 - 
getBeforeIndexpublic String getBeforeIndex(int part, int index) Returns the String before a given index.- Specified by:
- getBeforeIndexin interface- AccessibleText
- Parameters:
- part- the AccessibleText.CHARACTER, AccessibleText.WORD, or AccessibleText.SENTENCE to retrieve
- index- an index within the text >= 0
- Returns:
- the letter, word, or sentence, null for an invalid index or part
