Since:: 1.3
See Also:: AccessibleRelation

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.

Specified by:: getIndexAtPoint in interface AccessibleText
Parameters:: p - the Point in local coordinates
Returns:: the zero-based index of the character under Point p; if Point is invalid returns -1.
Since:: 1.3

getCharacterBounds

public Rectangle getCharacterBounds(int i)

Returns the bounding box of the character at the given index in the string. The bounds are returned in local coordinates. If the index is invalid, null is returned.

Specified by:: getCharacterBounds in interface AccessibleText
Parameters:: i - the index into the String
Returns:: the screen coordinates of the character's bounding box. If the index is invalid, null is returned.
Since:: 1.3

Specified by:: getCharCount in interface AccessibleText
Returns:: the number of characters
Since:: 1.3

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).

Specified by:: getCaretPosition in interface AccessibleText
Returns:: the zero-based offset of the caret.
Since:: 1.3
