JTextArea listener

[- ions]

Hello, i am relatively new to programming, Java being the first
language im learning. At the moment im having trouble changing the
setEnable value of a button, relative to the state of a JTextArea, ie
setEnable(false ) if the JTextArea is empty, and once somthing IS typed
into the TextArea the button is Enabled, i cant find any listeners for
JTextArea which help me, what ive got now is ok (button dosnt do
anything is the Area is empty) but not quite wot i want, help

Always remember to check the methods inherited from subclasses.
In this case JTextArea is a subclass of Component, JComponent
and JTextComponent. All of these have listener registration
methods for various types of AWT/Swing events.
