JTextArea
. BoundPropertyTextArea
is implemented to work with the property binding framework, particularly {@link net.helipilot50.stocktrade.displayproject.binding.adapter.DocumentAdapter}. DocumentAdapter
is a wrapper around a {@link javax.swing.text.Document} which listensfor {@link java.beans.PropertyChangeEvent}s fired by an associated {@link com.jgoodies.binding.value.ValueModel}and updates the underlying document to reflect the changes. DocumentAdapter
detects changes by the user by intercepting {@link javax.swing.event.DocumentEvent}s and updates the ValueModel
accordingly. The Forte behaviour is realised by associating an instance of ValueModel
with an instance of BoundPropertyTextArea
. BoundPropertyTextArea
makes use of two internal {@link java.beans.PropertyChangeListener}s and a {@link javax.swing.event.DocumentListener}. These determine whether a change to the associated bean model property was caused by the user typing in the text area or by a change in the backend. One PropertyChangeListener
intercepts PropertyChangeEvent
s before the DocumentAdapter
. The second PropertyChangeListener
intercepts PropertyChangeEvent
s after the DocumentAdapter
. It is the responsibility of the client to ensure that these listeners are registered in the correct sequence.
Refer to {@link net.helipilot50.stocktrade.displayproject.binding.TextComponentBinder} for an example ofusage.
The other advantage of this class is that it fires the same events as the Forte event model at the same time. @see net.helipilot50.stocktrade.displayproject.binding.TextComponentBinder @author Tim Faulkes
