Hi folks, I'd like to represent a byte[] field as a String in a JTextArea. Can anyone explain how to create such a Binder/Binding? Thanks Rogan |

Hi Rogan,
you need to extend AsYouTypeTextComponentAdapter and override
adaptedValueChanged with something like this:
protected void adaptedValueChanged(Object newValue) {
super.adaptedValueChanged(((String)newValue).getBytes());
}
You also have to reimplement TextComponentBinding to use your Adapter
and to set the bytes, i.e. you have to change line 41 like this:
textComponent.setText(new
String((byte[])valueModel.getValue()));
and implement an appropriate Binder (take a look at TextAreaBinder).
<http://dict.leo.org/ende?lp=ende&p=eL4jU.&search=appropriate>Of course,
if you need you have to handle encoding-specific conversions at the
places above.
Regards,
Arne

Thanks Arne,
That looks like it should do it!

I was looking at TextComponentBinding.java, and noted the Exception
handling:
protected JComponent doBindControl() {
final ValueModel valueModel = getValueModel();
try {
textComponent.setText((String) valueModel.getValue());
}
catch (ClassCastException e) {
IllegalArgumentException ex = new
IllegalArgumentException("Class cast exception converting '"
+ getProperty() + "' property value to string - did you
install a type converter?");
ex.initCause(e);
throw ex;
}
// TODO: implement ValueCommitPolicies
new AsYouTypeTextComponentAdapter(textComponent, valueModel);
return textComponent;
}
Would it not be sufficient to make an appropriate type converter?

That should be possible as well.
Most bindings have a specific required type, in this case a String. If
you bind a property to such a binding, then it requests a valueModel
with a specific type on the formModel. If the source valueModel (meaning
the first one wrapping the property) has a different type it will ask
the conversion service for a suitable converter to create a converting
valueModel from the source type to the required type and vice versa. So
creating converters in both directions and registering them should do
the trick. Take a look at the DefaultConversionServiceFactoryBean for
more information. There are a few converters registered there that you
can take as a reference.
Kind Regards,
Jan
