Field Detail

• CHARACTER

  static final int CHARACTER

  Constant used to indicate that the part of the text that should be retrieved is a character.

  See Also:

  getAtIndex(int, int), getAfterIndex(int, int), getBeforeIndex(int, int), Constant Field Values

• WORD

  static final int WORD

  Constant used to indicate that the part of the text that should be retrieved is a word.

  See Also:

  getAtIndex(int, int), getAfterIndex(int, int), getBeforeIndex(int, int), Constant Field Values

• SENTENCE

  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 Detail

• getIndexAtPoint

  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.

  Parameters:

  p - the Point in local coordinates

  Returns:

  the zero-based index of the character under Point p; if Point is invalid return -1.

• getCharacterBounds

  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.

  Parameters:

  i - the index into the String

  Returns:

  the screen coordinates of the character's bounding box, if index is invalid return an empty rectangle.

• getCharCount

  int getCharCount()

  Returns the number of characters (valid indicies)

  Returns:

  the number of characters

• getCaretPosition

  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).

  Returns:

  the zero-based offset of the caret.

• getAtIndex

  String getAtIndex(int part,
                  int index)

  Returns the String at a given index.

  Parameters:

  part - the CHARACTER, WORD, or SENTENCE to retrieve

  index - an index within the text

  Returns:

  the letter, word, or sentence

• getAfterIndex

  String getAfterIndex(int part,
                     int index)

  Returns the String after a given index.

  Parameters:

  part - the CHARACTER, WORD, or SENTENCE to retrieve

  index - an index within the text

  Returns:

  the letter, word, or sentence

• getBeforeIndex

  String getBeforeIndex(int part,
                      int index)

  Returns the String before a given index.

  Parameters:

  part - the CHARACTER, WORD, or SENTENCE to retrieve

  index - an index within the text

  Returns:

  the letter, word, or sentence

• getCharacterAttribute

  AttributeSet getCharacterAttribute(int i)

  Returns the AttributeSet for a given character at a given index

  Parameters:

  i - the zero-based index into the text

  Returns:

  the AttributeSet of the character

• getSelectionStart

  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.

  Returns:

  the index into the text of the start of the selection

• getSelectionEnd

  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.

  Returns:

  the index into teh text of the end of the selection

• getSelectedText

  String getSelectedText()

  Returns the portion of the text that is selected.

  Returns:

  the String portion of the text that is selected
