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 Accessible
)
and then calling the AccessibleContext#getAccessibleText
method of
AccessibleContext. If the return value is not null, the object supports this
interface.
Constant used to indicate that the part of the text that should be
retrieved is a character.
Constant used to indicate that the part of the text that should be
retrieved is a sentence.
Constant used to indicate that the part of the text that should be
retrieved is a word.
Returns the String after a given index.
Returns the String at a given index.
Returns the String before a given index.
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 AttributeSet for a given character at a given index
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.
Returns the number of characters (valid indicies)
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.
Returns the portion of the text that is selected.
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 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.
