How to Write a Caret Listener

Caret events occur when the caret — the cursor indicating the insertion point — in a text component moves or when the selection in a text component changes. The text component's document can initiate caret events when it inserts or removes text, for example. You can attach a caret listener to an instance of any JTextComponent subclass with the addCaretListener method.
Note: An alternate way of detecting caret changes is to attach a listener directly to the caret object itself rather than to the text component that manages the caret. A caret fires change events (not caret events), so you would need to write a change listener rather than a caret listener.

Whenever a caret changes its position or if text is selected, a caret event is fired by a text component. The class CaretEvent supports the methods getDot() and getMark() to retrieve the current location and the end position of a text selection, respectively.
